The Vincent Motorcycle Company in 1955 marketed the propeller driven 200cc Amanda Water Scooter.
A relatively recent but immensely popular addition to summertime leisure activities in the United States is the personal watercraft (PWC). Such vehicles have made it possible for people from all walks of life to enjoy fast-paced recreation on the open water without the encumbrance or expense of a full-sized boat.
The invention of both major types of PWC is usually credited to Clayton Jacobsen II of Arizona, originally a motocross enthusiast and inventor. Here is his first Personal Watercraft piloted in the UK in the 60's. This unit produced by Bomnbardier flopped and was shelved, when the patent was released Clayton took his next concept to Kawasaki.
The general public was introduced to such vehicles with the mass-marketing of Kawasaki's Jet Ski® in 1973. The original stand-up model, with a powerful 400cc engine and handlebar steering, allowed a person virtually to waterski without need of a boat. However, staying aboard the device was a challenge, especially in choppy water; so for some years, despite improvements in control and stability, PWCs acquired a very loyal but also fairly limited following.
1973 JS Kawasaki 400
A double breakthrough came in the late 80s, with the development and production of two-person watercraft in a sit-down style. Besides affording greater comraderie and comfort, these PWCs were more stable, safe, and user-friendly than their predecessors. By the early 90s, futher improvements in technology, from cockpit and hull design to engine and exhaust efficiency, had made sit-down personal watercraft quite easy to use. Their popularity skyrocketed---to the point that the Sea-Doo®, a sit-down PWC made by Bombardier, Inc., became the largest-selling boat in the world. Today, there are PWCs capable of carrying three persons and reaching speeds of 60 miles per hour.
The racing of souped up models, stand-up and sit-down, is an organized sport supported by competitions throughout the US. At the same time, personal watercraft have helped expand the concept of the waterside vacation, earning reserved areas on the country's lakes and shorelines. Being thrilling but safe, and easily accessible through rental as well as purchase, PWCs will continue to become more popular every year.
THE ORIGINAL PWC
Made from Bombarider, who produces the popular snow mobile line of Ski Doos, the Sea Doo was born:
An Italian made Nautical Pleasure Cruiser designed by Italian boutique design and engineering firm, Mival. The craft is the grandfather of the jet skis we have today, the craft requires the rider to hang on to its rear railing, instead of using the center seat ride. With a cruising speed of 5mph, get your hands on this for $8,000 as it was up for sale in 2011. Not very impressive.
Mival was known for the mopeds and motorcycles.
The inventiveness of the designers wanted to create a machine with the means to move in the water: the "Dolphin" (Delfino). A true jewel, a water karts or a vessel moved by two-stroke engine that, thanks to the thrust imposed to water, allows to move in the sea or lake without swim, even at 12 mph and without the risk of a propeller rotating. An ingenious means, that if you accidentally lose it underway the conductor starts spinning in circles, thus remaining easily accessible. The starter was a crank style, which wound up a spring on the flywheel once released generated the impetus for starting the single-cylinder. The "Dolphin" was a brilliant object for those enjoying SCUBA diving, being able to bring along oxygen tanks, a tool for rescue at sea and a thousand other possible uses in the ponds. Built out of fiberglass, the body was a constant float for a person in the water.
The operator would hold onto the bar on the stern, and the Delfino would drag the person behind it. The jetwash would be right at their head, but it was a relatively low impact water scooter. It was also referred to as the ‘WATER-KART’.
The power supply required a ratio 10% blend of oil to fuel mixture from a 125cc two stroke engine. The project was brilliant, so much so that the "I-Val" had sold the license in Canada, where the rebranded "Dolphin" was produced for a few years in the early 1960’s and then disappeared permanently from the commercial scene.

Quote from Youtube Channel: video of mi-val delfino world first personal watercraft from Canada, This was the worlds 1st personal watercraft, the Canadian government ordered from a company to build some for use. i believe it was a attempt to use it for military purpose, then i did not find on the internet any info about it, until a James Bond movie, Never say never again, in the battle of good vs evil the bad guys used it to their advantage. according to research only less then half a dozen are available in the world as of today. thank you for watching.

JETSKI WATER RESCUE TAKES OFF IN 1978
It all started here folks...
03-23-2012, 08:43 AM
In the thirty years since Kawasaki revolutionised water sports with the introduction of the JET SKI watercraft, the personal watercraft industry has become global in scope.
It all began in 1973, with the introduction of the WSAA (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/73MYJS400-A1.jpg) and WSAB (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/74JS400B.jpg), the world's first JET SKI watercraft. They were an instant success, leading to explosive popularity for this exciting new way to enjoy the water.
The personal watercraft has since evolved into a sophisticated, high-performing machine featuring the latest in engine and hull technology. JET SKI watercraft are now widely used for sport, recreation and water safety. With the growing usage of personal watercraft have also come increasing environmental concerns. As exemplified by the 4-stroke STX-12F, Kawasaki is committed to developing quiet, low-emission engines and advanced hull designs for personal watercraft.
It is a commitment we intend to pursue far into the future.
AND KAWASAKI CREATED THE JET SKI WATERCRAFT ... AND IT WAS GOOD.
Launching a revolution, the world''s first JET SKI watercraft took to the water. These limited production models were powered by 2-stroke twin-cylinder engines pumping out plenty of thrust for waterborne fun. Featuring greater manoeuvrability than any boat and extremely shallow drafts, they set the standards for the personal watercraft of the future.
The unique JET SKI watercraft feature of the fully enclosed impeller pump dramatically improved water safety over conventional outboard motors. Self-righting and self-circling features ensured that the craft would idle in circles at slow speeds if the rider fell off. The WSAA (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/73MYJS400-A1.jpg) and WSAB (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/74JS400B.jpg) could be distinguished by their hulls: the WSAA (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/73MYJS400-A1.jpg) featured a flat hull, while the WSAB (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/74JS400B.jpg) featured a V-type hull.

Kawasaki''s first mass production JET SKI watercraft, the JS400 (JS400-A), rolled down the slipways and into the hearts of the world''s fun seekers. Featuring an SMC hull, the JS400 was a popular machine among racers and thrill seekers alike.
Market demands for more power lead to development of the JS440 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/77-JS440A.jpg), an upgraded version of the popular JS400. The JS440 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/77-JS440A.jpg) offered more performance and became one of Kawasaki''s longest selling models, enjoyed equally by fun-lovers and racers.

The JS550 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/82-JS550A.jpg) was the first JET SKI watercraft to feature the newly designed, high-capacity mixed-flow pump. Driven by a water-cooled, 531 cm3 2-stroke Twin, the JS550 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/82-JS550A.jpg) pumped out plenty of thrust to satisfy the most power-hungry thrill seekers. Advanced technology included automatic rpm control to prevent over-revving when the pump was out of the water.
The lightweight JS300 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/86-JS-300.jpg) proved especially popular with new riders seeking an easy-to-operate JET SKI watercraft. Powered by a single-cylinder 294 cm3 engine with Superlube automatic fuel and oil mixing, the JS300 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/86-JS-300.jpg) was as easy to operate as it was to maintain.
DOUBLE THE FUN
A hybrid two-passenger model with stand-up and sit-down capabilities, the X-2 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/86-X_2-650A.jpg) finally allowed riders to share the fun with friends and family. Extra thrust came from a water-cooled, 635 cm3 2-stroke Twin pumping out 52 HP at 6,000 rpm via an axial flow pump. A water-jacketed exhaust system helped ensure low noise levels. The X-2 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/86-X_2-650A.jpg) was the first JET SKI watercraft to feature an adjustable handlebar and adjustable trim. Its great agility and motocross-like handling made it extremely popular. In order to be able to race these machines, a new race category was created; this category is known today as the "sport class".
Sales of the wet and wild 300SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/87-JET-SKI-300SX.jpg) commenced. This stand-up JET SKI watercraft was powered by a high-revving 294 cm3 reed-valve Single with CD ignition and water-jacketed exhaust.
The ultimate solo performance" was the catch phrase used when this high-powered stand-up model hit the water. A high-capacity axial-flow pump mated to the powerful 635 cm3 2-stroke Twin delivered tremendous thrust across the rev range. The 650SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/87-JET-SKI-650SX.jpg) featured a new V-hull design that increased stability during boarding and during high-speed manoeuvring.
The Kawasaki JET MATE (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/89-JET-MATE-650A.jpg) watercraft combined the engine and drive system from Kawasaki's popular 650-class JET SKI watercraft models with a 3-seat, boat-like hull. Other interesting technology included joy-stick control, a reverse system and a twin-tunnel hull design for high stability. Two hooks at the rear of the craft made it ideal for towing water skiers.
The two-seater Tandem Sport<SUP>TM</SUP> (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/89-JET-SKI-TS-650B.jpg), Kawasaki's first true sit-down JET SKI watercraft, rolled down the slipways. It featured big power from a twin-cylinder 635 cm3 engine and a step-through design. Automatic oil injection made for hassle-free fun.

03-23-2012, 08:48 AM
Sales of the high-performing 550SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/90JS550-BI.jpg) started. A mixed-flow pump, automatic rev limiter and self-circling mode made it an instant winner on the competition scene.
The updated 550SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/91-JS-550C.jpg) was released into a booming market for stand-up watercraft. Piston reed valves, aluminium cylinders and an underwater exhaust outlet for reduced noise levels were some of the new performance-enhancing features.
Also re-released this year was the upgraded 650SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/91-JS650-BI.jpg). Powered by a high-revving, in-line, twin-cylinder engine, the big SX satisfied the incessant craving of racers for more power. New underwater exhaust outlet reduced noise levels while allowing peak performance.
Another innovative watercraft, the SC (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/91-SC-650-AI.jpg) put an end to back-seat driving. Side-by-side seating, a 3-position steering wheel and the first JET SKI watercraft reverse system made it extremely easy to manoeuvre and operate. The fibreglass-reinforced hull was equipped with multiple storage compartments and integral flotation, making it virtually unsinkable.
An all-new twin-cylinder engine displacing 744 cm3 and fed by a huge 40 mm carb mounted to 8-petal reed blocks gave the 2-seater 750SS (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/92-JET-SKI-SS750A.jpg) (X-4 in Japan) a massive spread of responsive power. Rubber engine mounts improved comfort and reduced vibration stress on the rest of the boat. The tough, fibreglass-reinforced hull was fitted with storage compartments and a large-capacity fuel tank for long-range fun. The 750SS (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/92-JET-SKI-SS750A.jpg), Kawasaki's first high-performance runabout, was a popular choice among racers in the early days of the runabout class.
Racers and performance riders always want more power, and Kawasaki happily obliged with the mighty 750SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JS750-A.jpg). This high-performance stand-up model featured the same all-new engine as the 750SS (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/92-JET-SKI-SS750A.jpg), as well as an automatic bilge pump, an underwater exhaust outlet, Superlube automatic oil mixing, and a lightweight, highly manoeuvrable hull.
Sales of the Super Sport Xi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/93-JSuper-Sport-XI-750B.jpg), the first JET SKI watercraft to feature dual carburettors, started. More power from the 40 mm carbs and a 5-blade stainless impeller gave stunning performance to this two-seater hot rod. A trim system controlling the nozzle angle allowed the watercraft thrust angle to be trimmed for one rider or two, light weight or heavy.
The Super Sport XiR (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/94-XIR-750-D1.jpg) hit the water. This limited edition race-ready model featured an all-new carbon-fibre reinforced hull and came standard with an after-market exhaust system.
The ST (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JT750-A.jpg), Kawasaki's first three-seater JET SKI watercraft, was launched. LED instrumentation, reverse and a 46-litre fuel tank (the largest at the time) were just some of its user-friendly features.
GOOD THINGS COME IN THREES
The first of Kawasaki's 3-cylinder models, the 900 ZXi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/95-900ZXI-900A1.jpg) was powered by a newly designed 891 cm3 crankcase reed-valve engine fitted with a smooth-running 120° crankshaft. The combination of reed-valve induction and three separate carburettors delivered both highly responsive power at low rpm and screaming high-rpm performance on top. Other new features included electrically operated nozzle trim control that made it easy to adjust the nozzle angle to suit riding conditions. Advanced technology included a waterproof magnetic ignition key, electronic digital ignition, a 3-bladed stainless steel impeller and adjustable rear-view mirrors. The 900 ZXi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/95-900ZXI-900A1.jpg)'s innovative design made it "Watercraft of the Year".
The all-new 750 ZXi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/95-750-ZXI-750C.jpg) reached the showrooms. Featuring a 743 cm3 engine with the same frame and much of the same state-of-the-art technology as the 900 ZXi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/95-900ZXI-900A1.jpg), this exciting 2-person JET SKI watercraft was a popular lightweight alternative to the more powerful 900.
Also new for '95 was the 750 SXi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/95-750-SXI-750B1.jpg), a stand-up JET SKI watercraft with a powerful twin-cylinder engine, a 3-bladed stainless steel impeller and a long-life aluminium water muffler. This upgraded version of the 750SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JS750-A.jpg) was the first stand-up model with dual carburettors.
The latest iteration of the popular JT750 series, the 3-seater STS (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/95-STS-750B1.jpg) featured a powerful new twin-cylinder engine with dual carburettors, a fibreglass-reinforced RTM hull and a convenient reverse function. A tachometer and rear-view mirrors were standard equipment.
03-23-2012, 08:50 AM
Christened the 1100 ZXi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/96-1100-ZXI.jpg), this JET SKI watercraft was powered by a bored out version of the 900 ZXi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/95-900ZXI-900A1.jpg)'s 3-cylinder engine. Displacing 1,071 cm3 and churning out a massive 120 horsepower at 6,750 rpm, it was the most powerful personal watercraft on the market.
The three carburettors were fitted with accelerator pumps for instant throttle response and instant acceleration. Latest hull technology included a unique air induction system that reduced surface friction for a smooth top speed and twin KSD (Kawasaki Splash Deflector) to control water spray. KATS (Kawasaki Automatic Trim System), a stainless steel impeller, a comprehensive set of four analogue instruments (speedometer, tachometer, fuel gauge and trim indicator) and a digital clock were only some of the features that made the 1100 ZXi King of the Fleet.
Updated for '96, the 750SS (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/96-750SS-750E1.jpg) (X-4 in Japan) benefited from increased engine power, an improved electric trim system, a new impeller for more thrust, and improved rough water performance.
The latest version of the Super Sport Xi (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/96-Super-Sport-XI750F1.jpg) was baptised. Upgrades included more power and improved durability for the engine, a new quick-planing hull with KSD and larger, more race-oriented sponsons, and a larger, more comfortable seat.
Sales of the 900 STX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/97-900STX.jpg) commenced. Huge power from a 3-cylinder 891 cm3 engine, seating for three and a rugged, highly manoeuvrable hull made this JET SKI watercraft the top machine in its category.
Rock 'n roll on water! That's what riders thought the first time they opened the throttle on the amazing 1100 STX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/97-1100STX.jpg). The combination of the 1100 ZXi engine and a hand-laid fibreglass hull with an all-new "cab-forward" design and a 3-person seat made the 1100 STX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/97-1100STX.jpg) the ideal runabout for family outings and coastal exploration. Large sponsons on the hull helped it reach planing speeds very quickly. LCD multifunction meters, a large-capacity 53-litre fuel tank and the only standard-fit retractable boarding step in the industry were only some of its leading features.
The Xi Sport (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/98-XI-Sport-750.jpg) hit the water in style with a powerful twin-cylinder engine, a fibreglass-reinforced SMC hull and a lanyard engine stop switch.
Racers' delight! The SXi Pro (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/98-SXI-Pro-750.jpg) was released and immediately dominated racing. Massive twin-cylinder horsepower and impeccable handling from a new hand-laid fibreglass hull with a lower centre of gravity for more race-oriented performance made the SXi Pro (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/98-SXI-Pro-750.jpg) an instant winner.
Sales of the 750 STX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/98-750STX.jpg) commenced. This three-person sports model shared its hull with the larger 900 STX and was loaded with rider-friendly features which gave it broad-spectrum appeal.
The updated 1100 STX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/98-1100STX.jpg) was the first JET SKI watercraft to feature CDCV carburettors. Still used on present-day carbureted models, CDCV carburettors offered improved starting, better fuel economy and enhanced reliability. Other improvements included a larger oil tank, a large storage area added under the seat, and a tachometer added to the instruments.
Released exclusively in Japan, this commemorative edition of the 550SX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/98-500SX.jpg) featured an all-white body with "JET SKI" and "550SX" logos. Each of the 300 units was individually numbered.
By 1999, the horsepower wars were in full swing, and the "Ultra 150" model name hinted at this impressive machine's close to 150 horsepower. The all-new engine had a displacement of 1,176 cm3. Nikasil-plated cylinders increased durability and performance while reducing engine weight. Kawasaki's Throttle Responsive Ignition Control (KTRIC) continuously altered the timing of the digital ignition for each individual cylinder to suit operating conditions. Oval-shaped leading edges on the impeller blades maximised efficiency while reducing cavitation. A hand-laid fibreglass stepped hull with deep-V design gave the Ultra 150 excellent handling performance.
Released in Japan to commemorate Kawasaki's victory in the IJSBA Runabout championship, only 300 units of this limited edition racer replica were produced. Based on the 1100 STX, the 1100 STX-Limited (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/99-1100STX-Limited.jpg) featured Kawasaki works colouring and 2-piece sponsons.
The updated 900 STX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/99-900STX.jpg) arrived. Improved power characteristics, the "cab-forward" design of the 1100 STX with enhanced ergonomics and larger fuel and oil tanks were just some of its many new features.

GOOD CLEAN FUN!
Revolutionary was the word most journalists used to describe the D.I. (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JTT1100-C.jpg)'s clean-burning direct-injection 2-stroke engine. This remarkable system injected the optimum amount of fuel directly into the combustion chamber for significantly reduced exhaust emissions and excellent throttle response. Fuel usage was reduced by 30% and oil consumption by up to 50%, for increased range, longer play time and lower operating costs - all without any sacrifice to the 3-cylinder engine's impressive performance.
A resonator added to the exhaust system further reduced noise levels. A new deep-V hull with triple KSD provided excellent rough-water handling - this hull was used on the championship-winning racers. Comfortable three-person seating, a roomy deck area with multiple storage compartments, and a retractable boarding step made the 1100 STX D.I. (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JTT1100-C.jpg) the most versatile JET SKI watercraft in the Kawasaki line-up.
A third version of the 900 STX (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/01-900STX.jpg) was released. Upgrades included the brilliant-handling hull from the 1100 STX D.I. (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/01-1100STX-D.I.jpg), a spacious stowage area under the front hood, and a more comfortable seat.
Also re-released in '01 was an upgraded version of the 1100 STX D.I. (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/01-1100STX-D.I.jpg) Enhanced engine performance, reduced exhaust emissions and the Kawasaki Smart Steering™ system (KSSTM), a system that helps the rider turn at running speed, even when the throttle is not being applied, were featured.
The Ultra 130 D.I. (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/01-Ultra-130-D.I.jpg), a direct injected version of the Ultra 150 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JH1200-A.jpg) watercraft, made its debut. Emissions of the direct-injection engine were low enough to meet 2006 EPA standards.
Get it on! Combining the awesome power of the Ultra 150 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JH1200-A.jpg) watercraft with the rough-water capability of the 1100 STX D.I. (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/01-1100STX-D.I.jpg), the high-performance 1200 STX-R (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/02-1200-STX_R.jpg) is a slicked-down runabout specially designed to form the basis for a race machine or for riders looking for maximum excitement on the water. The powerful 1,176 cm3 3-cylinder engine breathes via three CDCV carbs. Other race-oriented technology includes a race-developed ride plate and sponsons, and a racing style stepped seat. This engine-hull combination won both the national and world championship titles.
NINJA PERFORMANCE ON THE WATER!
Kawasaki takes the lead in the 4-stroke watercraft revolution with the launch of the impressive STX-12F (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JT1200B-S321C.jpg), with its Ninja ZX-12R-based 4-cylinder engine. Offering an unbeatable combination of massive power, clean emissions and quiet operation, the fuel-injected, 1,199 cm3, DOHC engine instantly put the new STX-12F in a class of its own. Whether zooming 3-up across the water, towing skiers or exploring a barren coastline, the combination of this impressive power plant and the race-derived hull provide plenty of performance for waterborne fun. Superb ride quality, ample stowage area and plenty of power for towing skiers or wakeboarders make the impressive STX-12F (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/JT1200B-S321C.jpg) the sensation of the year.
With the release of the high-performing 800 SX-R (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/03-800SX_R.jpg), Kawasaki changed forever the status quo of stand-up watercraft. Balancing ease-of-riding and high performance in a single package, this remarkable JET SKI watercraft satisfies everyone from beginners to pro racers. Its wide design makes it extremely stable, making it easy to ride for beginners, and while it can turn with minimum banking, the 800 SX-R (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/03-800SX_R.jpg) can just as easily make sharp, banked turns.
Its high-revving, 781 cm3, 2-stroke, twin-cylinder engine fitted with dual Mikuni BN40-38 carburettors delivers crisp throttle response and impressive acceleration. High performance deck features include rubber-topped side-deck fins, for easy boarding or as handy leg rests when cranking tight turns. And the ergonomically designed handle pole has minimal forward-backward movement to reduce rider fatigue. Race or rip, the 800 SX-R (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/03-800SX_R.jpg) is the stand-up model to beat in '03.
KAWASAKI, JET SKI AND PWC RACING
It wasn't long after the introduction of the first JET SKI watercraft that people began to look for avenues in which to race them. Kawasaki, working together with watercraft enthusiasts and aftermarket companies, helped create the United States JET SKI Boating Association (USJSBA) in 1980, establishing an organised environment for competitive racing. Two years later, the USJSBA re-charted to become the International JET SKI Boating Association (IJSBA) to accommodate the growing interest in JET SKI racing around the world.
In the beginning, only stand-up JET SKI watercraft were being raced - namely the JS440 (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/MAC_Ski1.jpg) - but when the X-2 was released a new race category, the "X-2 class" (now called the "sport class"), was created to allow these models to compete as well. Later, when the "runabout class" was created, Kawasaki's SS was again a popular choice among racers.
In 1993, the IJSBA was renamed the International Jet Sports Boating Association, opening the doors for competition aboard any brand of personal watercraft. The presence of other manufacturers made the competition scene more intense and helped the sport to grow. In 1995, Kawasaki became the first manufacturer to create a factory-supported PWC racing team.
Involved in the racing scene since the beginning, Kawasaki has won numerous championships over the years. Machines like the championship-winning 1200 STX-R (http://www.kawasaki.ca/skins/default/content/frontend/images/common/sections/corporate/jet-ski/MAC_Ski2.jpg) and the 800 SX-R will ensure that Kawasaki continues to be a dominant force well into the future.

YAMAHA Waverunner History
Yamaha’s first personal watercraft, the WaveRunner, started to appear in retail stores in 1986, with the invention of the Yamaha WaveRunner 500. Yamaha broke into the personal watercraft market after Kawasaki’s Jet Ski and Bombardier’s Sea-Doo had started to see a spike in sales. Despite the names Jet Ski and Sea-Doo being brand specific names for personal watercraft, the names have now become synonymous with all stand-up (Jet Ski) and sit-down (Sea-Doo) personal watercraft. The WaveRunner marked Yamaha’s entry into the lucrative personal watercraft market, and soon the WaveRunner personal watercraft was considered top of the line.
Before 2000, Yamaha had cycled through several different names for their personal watercraft including the WaveJammer, WaveBlaster, and WaveRaider. These names represented specific models of personal watercraft, but as of 2000, all of Yamaha’s personal watercraft are named WaveRunner, with a different designation of model attached to the end, for example, the WaveRunner XLT 1200. Yamaha also formulated their Yamalube 2W oil (http://www.domo-online.com/yamaha2w) for specific use with their WaveRunner personal watercraft.
These small-hulled craft are driven by a jet-propulsion system and have a seat that you sit on like when riding a horse and an open stern that makes for easy mounting and dismounting on the water. These marine sport watercraft loved by people all over the world today were introduced by Yamaha in 1986 for the first time in the world.
To this new type of watercraft that have no protruding parts on the bottom of the hull and are easily righted and ridden again should they happen to capsize, Yamaha applied its famous small-engine technology to make vehicles that are truly reliable, fun and functional. With its capability to run freely across great expanses of water, Yamaha named its revolutionary invention the WaveRunner, and it became a big hit product that let people experience a refreshingly exciting and fun form of sound marine recreation anyone can enjoy. Since their release, these WaveRunners have been continually refined and their popularity has spread to the point where they are now used in over 120 countries worldwide. Here is an outline of their history.
WaveRunner 500 (Marine Jet 500T)
Yamaha released the WaveRunner 500 (Marine Jet 500T), the world's first sit-down type open stern production PWC. This is the model that created today's PWC market. As an agile craft that many people could enjoy with a sense of assurance, it sent shockwaves through the small watercraft industry.
WaveJammer 500 (Marine Jet 500S)

Although the first Sea Doo watercraft (http://www.oldseadoos.com/) really appeared in 1968, for our purposes, we’ll be starting with 1988 since that’s the first year for the “modern” Sea Doo PWC. Also, if you hold your mouse over an image without clicking, it should display the year and model to help with identifying the pictures.
A brief rundown of the modern history of the Sea Doo model line...
<HR>Although I don’t recall ever seeing one, Sea Doo first “arrived” in 1988 with a unique hull design and seat that opened different than the 1989 and up. It was equipped with the 587 Yellow motor which was in all Sea Doos from 1988 to 1991. The SP is technically a 2 passenger machine although that hull was pretty tippy with anything more than a couple kids onboard. I would guess not many were sold since they’re pretty scarce compared to the 1989 SP. The person below sent me the pictures and info on his really nice 1988 so I added it below. If anyone else has one of these, info on it, or pictures of them, I would love to add it to this page too!.
“You stated that you had not seen and did not have a picture of a 1988 first year Model 5801. I was a July 1988 purchaser of the first year model and still have it. It has not been stored and has been used every summer since 1988. It is original (except for batteries and impeller) and the engine is completely original (rings, pistons, etc.). I have used BRP two stroke oil exclusively and the heads of the pistons are clean and carbon free. The 1988 had a rear hinged seat with piston support that opened clam shell style rather than coming off like the 1989. I have attached photos taken last year of the 1988 and the engine. It is literally showroom.” – YOU WEREN’T KIDDING! SEE THE PICTURES BELOW.
http://www.seadoosource.com/models/1988sp1s.jpg (http://www.seadoosource.com/models/1988sp1.jpg) http://www.seadoosource.com/models/1988sp3s.jpg (http://www.seadoosource.com/models/1988sp3.jpg)
<HR>The 1989 SP had a new engine access design which Sea Doo will stick with on all future models. It features a removable seat that comes off to access the engine and electrical. Sea Doo will stick with this “squared off” hull design on the SP through 1993.
<HR>In 1990 Sea Doo kept the SP in the lineup and also introduced the first 3 passenger GT model which featured a basically smooth hull which was fun for spins, but also could get pretty unstable with three. Since it had the 587 (twin carb), it also wasn’t the most powerful or fast but the old 587 was pretty indestructible. The GT also was the first time Sea Doo introduced the reverse feature on a ski.
<HR>In 1991, the SP and GT (basically the same machines as 1990) were in the lineup, plus the XP makes it’s first appearance. The XP was basically the SP hull with the Twin Carb 587 installed. The XP hull did feature a hood with mirrors for the first time. Sea Doo also finally added a grab handle to the SP which really helped with reboarding!
http://www.seadoosource.com/models/1991sp.jpg http://www.seadoosource.com/models/1991spi.jpg http://www.seadoosource.com/models/1991gt.jpg
03-23-2012, 09:05 AM
In 1992, the white 587 engine makes its’ first appearance and the yellow one is history. All models in 1992 are equipped with the 587. The SP and XP basically were the same as 1991, but the XP now shows the first appearance of trim, although manual for this year.
The GT now changed its’ name to the GTS but also remains pretty much the same as the 1991 with the exception of a white lower hull with strakes instead of the grey smooth GT style.
http://www.seadoosource.com/models/1992sp.jpg http://www.seadoosource.com/models/1992spi.jpg http://www.seadoosource.com/models/1992xp.jpg http://www.seadoosource.com/models/1992gts.jpg http://www.seadoosource.com/models/1992gtx.jpg
<HR>In 1993, we see the first larger cc engine with the 657 in the XP. The XP also features a new design hull and rounded more modern body pieces as well. A pump with more durable bronze vanes also was used on the XP. The 1993 XP is the first to have electric trim available as well. In 1993 the SPX (587 dual carb), which was basically the 1992 XP, is in the lineup. Sea Doo continued to do that with the SPX for most of the ‘90s as well. The SP (587 single carb) was offered as well as the SPI (587 single carb) which had a stainless impeller and a different pipe.
The GTS 3 seat was in the lineup and the first GTX 3 seater made it’s appearance. The GTX wasn’t much different than the GTS although it did have a fuel gauge and a couple other options not found on the GTS. The GTX also had a little more power due to dual Mikuni carbs.
http://www.seadoosource.com/models/1993sp.jpg http://www.seadoosource.com/models/1993spi.jpg http://www.seadoosource.com/models/1993spx.jpg http://www.seadoosource.com/models/1993xp.jpg http://www.seadoosource.com/models/1993gts.jpg http://www.seadoosource.com/models/1993gtx.jpg
03-23-2012, 09:12 AM
In 1994 we really start seeing Sea Doo update the design on the new models. The SP (587 single carb) and SPI (587 single carb) are again offered and were popular in the rental field. They also offered the SPX (657 dual carb), which was basically the 1993 XP. The XP for 1994 featured the 657X engine that had more hp than the standard dual carb 657. As far as features go though, the 1994 XP was pretty much the same as the 1993. They also offered an XPI (657 dual carb) but I can’t remember what differentiated it from the XP.
The GTS was pretty much the same ski as the 1993 GTS, but the GTX now features the 657 engine and bronze vane pump, as well as a full compliment of gauges and even mirrors so you can pull a skier.
http://www.seadoosource.com/models/1994sp.jpg http://www.seadoosource.com/models/1994spi.jpg http://www.seadoosource.com/models/1994spx.jpg http://www.seadoosource.com/models/1994xp.jpg http://www.seadoosource.com/models/1994gts.jpg http://www.seadoosource.com/models/1994gtx.jpg
<HR>In 1995 we get our first glimpse of two new larger engines when the 717 and 787 make their first appearance. The SP (587 single carb) and SPI (587 single carb) are in the lineup once again. The SPX (657X engine) is once again basically the 1994 XP with different colors.
The GTS is basically the same ski as the 1994, but the GTX gets the 657X engine as well as sleeker looking mirrors. An optional Touring Seat (hard to come by these days) offered on the GTX (it’s shown on the GTX picture below) made the GTS and GTX really ride well, although it was molded to seat two instead of the flat seat that could accommodate three. That seat will fit all the 1990-2001 GT style hulls and could be found in purple/green, purple, and yellow.
The XP now gets the new 717 engine, which was the largest rotary valve motor released in a Sea Doo. It also features a different design trim system and a pump extension to increase the water volume in front of the pump. The XP800 also is released in limited numbers and it features the 787X RAVE valve engine. Now we’re talking some power!
The final new release for 1995 is the HX, which really is basically a motorcycle for the water. I believe Sea Doo released it to compete in the same racing class as the Yamaha WaveBlaster and it had similar riding characteristics as well as a 717 engine for power. It’s a long narrow ski that takes some getting used to but is lots of fun once you get the hang of it. What it featured that made it really unique though was the first appearance of a seat with a suspension.

In 1996, the 657 engine is totally phased out and won’t be seen again in a PWC. This year, we also see Sea Doo switching to the DESS ignition system which lots of people have varying opinions on. It allowed for better monitoring of the Sea Doo engine functions as well as security, but also makes the MPEM dramatically rise in replacement price. Now you need to take it to the dealer if you lose your lanyard as well.
The SP (587 single carb) and SPI (587 single carb) are in the lineup yet again. The SPX (717 dual carb) is once again basically the 1995 XP with different colors. The XP now features the 787 RAVE engine and is probably the most desirable of the X4 hull design models built. The HX (717) stays in the lineup as well and stays basically unchanged besides graphics.
We still have the GTS (587 single carb) in the lineup, but we get the new GTI which is the same hull design as the 1995 GTX but with a 717. The GTX is the first really new 3 passenger hull design since 1990 and features larger front storage, a two piece removable seat, and the 787 for adequate power for about anything you want to do.
This year we also get a new model 2 seater in the GSX. It’s powered by the 787 and is slightly slower than the XP but more stable with two. The GSX and the GTX are the first now to also incorporate a digital infocenter that gives you lots of information instead of just a couple functions of the old 2 ones.

<HR>In 1997 the original 587 engine that started it all is totally phased out and won’t be seen again in a PWC. New this year though is the release of the 130hp Rotax 2 cylinder 947 RAVE engine, the largest of all the two stroke Sea Doo engines and the most horsepower per cc of any PWC engine out there!
The SP (717 single carb) is still in the lineup but its’ days are numbered. The SPX (787 dual carb) is once again basically the 1996 787 XP with different colors. The XP is a new hull design with the 787 RAVE motor located in the front and a suspension seat like the HX. Quite a different ride than the X4 hulls! The HX (717) stays in the lineup as well for 1997.
This year, the GSX (dual carb 787) also gets a couple more models in that hull platform with the GS (717 single carb) and the GSI (717 single carb). The GS is the base model with pretty much no features with only a fuel gauge and no trim while the GSI and GSX have the digital infocenter and electric trim. The late production GSX Limited features the new 947 white engine with 130hp. Since this is the first time we see those, they also have quite a few bugs that get worked out in the later silver engines.
The 717 GTS is the base model 3 seater still featuring the old style hull and is basically the same ski as 1996 GTI with no infocenter. The GTI for this year gets the new style hull like the 1996 GTX but has the smaller 717 engine and no infocenter, just gauges. The GTX for 1997 is almost exactly the same ski as the 1996 even down to the colors.
It’s worth mentioning this year marks the beginning of the use of the new style ignition module. Instead of components being in a waterproof grey box, most everything plugs into and goes through the MPEM mounted on a plate usually in the front of the ski. Although the design works well, from now on it’s going to cost quite a bit more for a new MPEM. The only exception is the SPX and GTS, which will continue to use the old style.
On a final note, late in 1997 the GSX Limited with the 130hp 947 RAVE engine also is released but it’s actually considered a 1998 model.

In 1998 we lose some models, but in exchange get the new 787 RFI Fuel Injected RAVE engine. Due to new stricter environmental rules, the push from now on will be towards more fuel efficient, less polluting PWCs.
The SP (single carb 717) is in the lineup for the last year. This year the SPX is basically the 1997 SPX but loses a little weight somewhere, making it the lightest one of all the X4 hulled 787 SPX models so probably the most desirable one. The XP keeps the same hull design as the 1997 but also now adds Limited to the name and comes with the 947 (dual carb).
The GS (717), GTS (717) and GTI (717) basically don’t change anything besides colors from 1997.
The GTX comes for the first time with a 787 RFI engine which offers the same power as the 787 carb model, but improved fuel economy and better emissions. The GTX as well as the GSX now have Limited added to their names and come with the new 130hp 947 carbureted engine and that really gives them some life. The white 947 engine is gone and replaced with a better design silver one as well.
Since late 1997 is the first year for the 947 engine, on the first models they do have some problems with water ingestion as well as some pump issues, but most should have been repaired and updated under warranty.

In 1999, not much new comes out probably due to Sea Doo putting all its’ efforts into the upcoming 2000 models.
The SPX (787) is basically the same X4 hull as the 1997-1998 SPX, but for some reason slightly heavier than the 1998. This will be the last year you’ll see that hull design offered.
The GS (717), GTS (717) and GTI (717) basically don’t change anything besides colors from 1998.
The GTX RFI (787) is in the lineup again as well as a new GSX RFI (787) model. The 947 powered GSX Limited, GTX Limited, and XP Limited are basically the same skis as 1998 although they had most of the bugs worked out now.

<HR> In 2000 we get a whole bunch of new models, a new DI engine and some bold graphics to let you know they’re a 2000 model. As said previously, my guess the lack of new models in 1999 was so they could hit us with all these cool skis for the new millennium!
The 717 GS, 717 GTS and 717 GTI basically don’t change anything besides colors from 1999. The GTX RFI (787) as well as the GSX RFI (787) model are in the lineup and pretty much unchanged from 1999. Sea Doo drops the Limited designation on the 947 skis this year too. This year, we also have the GTX and XP that are basically the same as 1999.
Now for the new. This year Sea Doo comes out with the 947 DI engine which offers the same power as the 947 carb model, but improved fuel economy and better emissions. That engine goes in a GTX DI and a new model, the RX DI. There is also a base RX with a 947 carb engine and the new but short lived LRV (dual carb 947). The LRV has to be the largest PWC ever made seating 4 and taking up lots of space in the garage!

In 2001, this is the last year we see the 717 GTS that used the old style hull (1990-2001) (possibly actually phased out in 2000).
We get a new GTS though and it’s basically the same as the GTI, but with less bells and whistles. It may use a different hull than the GTI as well but not sure on that one. We also see the 717 GTI in the lineup again.
The GSX RFI, GTX RFI, GTX DI, RX DI, GTX, RX, XP and LRV all basically are the same machines as the 2000.
There is one big change for 2001 though in the form of two color options for almost every model. We do also see a limited production race machine designated RXX which I’ve read is the fastest stock production 2 stroke ever made.

In 2002, we see the first of what will become the base of all Sea Doo power to come. I’m referring to the 1503 4-TEC 3 Cylinder 4 Stroke engine. We also see the OPAS (Off Power Assisted Steering) first this year as well on the GTI LE (717) and the GTX 4-TEC. This year, we still have many of the same 2 strokes including the GTI, GTX, GTX RFI, GTX DI, RX DI, RX, and XP. The GTI LE is basically the GTI but with a different hull featuring OPAS. The 2002 GTI LE, GTX DI and GTX 4-TEC also now use a different design upper hull utilizing a new style hood and different seat design than 2002. New this year also is the LRV DI.

03-23-2012, 09:19 AM
In 2003, we see the first Supercharged 4-TEC in the GTX model. We still have the GTI (717) and the more optioned GTI LE (717) as well as the new GTI LE RFI (787 RFI). We also still have the standard 155hp GTX 4-TEC, GTX DI, RX DI and XP DI and LRV DI. This is the last year though for the LRV due to poor sales I would imagine. This is also the last year for the RX model.

03-23-2012, 09:20 AM
In 2004, we start to see the direction Sea Doo and most of the PWC industry is headed with more 4 strokes and less 2 strokes in the lineup. This is the first year for the new Supercharged RXP, which I would guess was meant to be the replacement for the 130hp RX model. What a replacement!
This year we still have the GTI (717), GTI LE (717), and GTI LE RFI (787 RFI) models as well as a new GTI RFI (787 RFI) model. The GTX 4-TEC and Supercharged models are still in the lineup as well. It’s worth mentioning that the majority of the 2004 models haven’t changed and even have the same color scheme as 2003 which I would guess was probably since Sea Doo put most of their resources into developing the RXP.
Although the XP DI is in the lineup again, this will be the last year for the XP model line. Also, as mentioned this is the first year for the RXP and it turns out to be arguably the most popular Sea Doo in years.
Maintenance note… the new supercharged 4TEC models are having lots of problems with the drive. The ceramic clutch discs are great at dissipating heat but they break easy. The pieces get into the oil system and it’s quite a job and expense to clean them out. If an owner of one of these skis notices it slipping, they need to get it in for service BEFORE it breaks!

03-23-2012, 09:20 AM
In 2005, we still have the GTI (717), GTI LE (787 RFI), and GTI LE RFI (787 RFI) models as well as the GTX 4-TEC and Supercharged models. A new model to appear is the GTX (4-TEC) Wake model which is set up for wakeboarding and similar activities.
The new 4 stroke model for this year is the RXT Supercharged model. It’s basically the two passenger model of the RXP and is a little longer and slower than the RXP. As for the RXP, it’s basically unchanged from 1994 besides different trim. Both the RXP and RXT come in either Red or Green color schemes this year.
Finally, I would guess since they pulled the XP in 1994, Sea Doo also released a new single seat 2 stroke model called the 3D, equipped with the 787 RFI engine. The ski is kinda like the transformers toys you might have had as a kid. It changes from stand up to sit down and all together there ends up being 5 different riding combinations you can use on the ski. Although it isn’t a very popular ski, I have heard it’s a whole lot of fun to ride!

03-23-2012, 09:21 AM
In 2006, you really start to see the way Sea Doo is headed with the emphasis on 4 stroke models. All 2 strokes have been eliminated with the exception of the 3D, which now has the more powerful 947 DI installed.
The GTI models are all 4 stroke powered now and the GTX models from last year are also are in the lineup. The RXT and RXP also of course are back as well.
By now, the only real mechanical fault worth mentioning is well known among those who own the Supercharged models. The infamous clutch problems! Sea Doo addresses it with a heavier duty clutch package and aftermarket sources also have good solutions available.

03-23-2012, 09:21 AM
In 2007, all models from 2006 are offered but in different colors than last year. The only real new addition is a 155hp RXP which has been a big debating point on the many Sea Doo forums. It’s a bit like putting a V6 in a Corvette, but those who are less experienced riders would most likely benefit from the less powerful model. The RXP (maybe RXT too) does have a change to the steering column making it more vertical and people say that’s an improvement. This is the last year for the poor selling 3D DI too although from what I’ve read, anyone who has actually owned or rode one loves them! A salute and RIP to the two strokes that started it all!
Maintenance note… There’s still problems with the supercharger drive but new metal washers make them last much longer. Still, if you notice a lack of rpms, get your ski in for service BEFORE it breaks!

In 2008 BRP hits us again with two new models… the RXP-X and the RXT-X. These have an incredible 255hp and are the most powerful PWCs ever. I believe Sea Doo picked the 255hp option to combat Yamahas 250hp ski and these new models blow any other ski away for acceleration, handling and features. From 0 to 50mph in 2.9 seconds, you almost need a seat belt!
With all these great features though people lose the fact that these now are so complicated and expensive that we’ve totally gotten away from what a PWC originally was. These are basically boats that have to go to a dealer for even the simplest maintenance needs.
A note about the ever increasing HP figures… Although Sea Doo and other PWC manufacturers have always had a constant battle to put out a ski that one-ups the competition, you’ll notice that any new ski (no matter who makes it) will ever go past 70 mph. The reason for that is the PWC manufacturers have an agreement with the USCG (and maybe insurance companies too) to keep the speeds in check. The way Sea Doo does it is to limit the hull design. They put out huge hp but then the add weight and design the hull so it’s really hard to get over 80mph safely. Yamaha has a great lightweight hull but limit speeds with the drive train design. What’s really interesting about that is now people are putting the RXP engine in the Yamaha hull and have built the first PWCs that will break the 100mph barrier. You couldn’t pay me to ride on a PWC going that fast though!

In 2009 there isn’t much change in the lineup or performance with the exception of the new iS concept. The iS stands for "Intelligent Suspension" and from what I hear, it offers an incredible ride. Although the new GTX Ltd iS is a really incredible state of the art craft with intelligent suspension, intelligent throttle, and even brakes, it seems to me that Sea Doo is trying to make an idiot proof ski anyone can ride. I’ve found though it’s much better to keep the idiots off the water than giving someone with no common sense or skill a product that’s easier to operate. From what I see too, this outrageously expensive ski looks like a nightmare to repair if it breaks so make sure you get an extended warranty if you’re planning on buying this $16,500 machine!
A comment on the supercharger issues... Sea Doo now installs metal supercharger washers in all the Sea Doo models that are supercharged. They still can fail though so therefore Sea Doo calls for the supercharger to be rebuilt every 100 hours. Many dealers won’t tell a person that when buying a ski so keep that in mind if you own one or are considering purchasing a supercharged model. I’ve been hoping for a better design with less maintenance but I now believe that’s not going to happen.

In 2010, the lineup is pretty much the same as last year but with the addition of the RXT iS 260. The GTX iS also is now also 260hp. Not sure where the extra 5hp was found but it’s once again probably a bragging thing. Not sure why they didn’t give the RXP-X the 260hp badge but maybe they’re saving that for 2011.
You would think I would be impressed with all these new models and new features but I’m not. As I’ve stated before, I don’t like complicated expensive skis that few can afford. The ski I probably like best in the 2010 lineup is the lowly GTI that’s the least expensive Sea Doo you can buy at $7,999. The reason though I like the GTI is mainly the color. I’ve never seen anyone release an almost all white PWC and that’s pretty cool. This one should be popular with people who own large yachts since they generally like a ski that blends in with their yacht and looks like it belongs there. While on the subject of color, anyone who has been in the tropical sun knows that dark colors on a boat aren’t the smartest idea since they get really hot. Therefore I can’t imaging how you can walk up and hop on a new RXP-X or RXT-X once it’s been setting out in the sun in South Florida for any length of time!

What’s up with these prices?!! The GTI and the GTI SE are now the only skis left that are below $10,000. Aren’t manufacturers paying attention to the economy? We can’t afford these crazy prices these days! Gone are the days of a $5000 ski and even used 4 stroke ski is priced crazy. The cost of a PWC these days now seems to be getting way out of the reach of pretty much anyone except those with exceptional credit. As many people have found out too, the banks aren’t giving out that stimulus money they got from us. The only good thing about these high priced new models is they’re fueling the resurgence and resurrection of the ‘ol 2 stroke smokers and I like that!

The first JETSKI motorized concept
"The First Jet-Ski" <TABLE class=contentpaneopen><TBODY><TR><TD vAlign=top colSpan=2>http://www.wheelsthroughtime.com/images/stories/bodyphotos/firstjetski.jpg
Resting in the "Home-made in America" exhibit at Wheels Through Time is an oddity dating back to the earliest days of personal motorized watercraft. While it remains unknown exactly when the first personal watercraft appeared, it is believed that the machine housed at the museum is the earliest known example.
Featuring a 74 cubic inch 1925 Harley-Davidson JD engine, "The First Jet-Ski" provides a unique deviation from standard applications where motorcycle engines were used to increase machines' capabilities. As the machine was most likely built for recreational purposes, the Harley-Dvaidson power-plant has been converted from air-cooled to water-cooled, in order to keep from overheating due to high revolutions at low speeds.
The hull is made of lightweight sheet metal, and features a groved rubber standing surface. The machine transmits its power through a shaft to a 4-blade propeller, with automotive-like floor-mounted gas pedal, and is steered by rope.
While few early examples of motorized personal watercraft survive today, there have been several attempts by motorcycle manufacturers during the mid-20th century to develop this now popular recreational sport. Some were more successful than others.
It is believed that the unexpected demise of the Vincent Motorcycle Company was a result of the production and marketing efforts for their propeller-driven 200cc "Amanda Water Scooter" in the mid-1950s.
Dated to the late 1920s or early '30s, the machine rests in its original condition and is on permanent display for museum visitors to enjoy.

ECO JETSKI - Electric powered JETSKI
Electric cars have been getting plenty of attention recently, but what about electric jetskis? The ECO Jetski–the first all-electric jetski–reaches speeds of 50 MPH and has an impressive battery life of three hours
THE SAMBA- Electric Powered Personal Watercraft
Part jet ski (http://www.engadget.com/2009/05/26/eco-watercraft-electric-waverunner-makes-no-sound-burns-no-fuel/), part electric water scooter, 100 percent awesome. That's the Exoconcept Exo -- a new sea-born vehicle for stealth missions and the occasional run-in with Mr. Living Vicariously. The craft comes in a few flavors with shells made of high-end carbon fiber or ABS plastic, and engines ranging from 3.5-7kWh. Capable of cruising the open waters at a max speed of 15-27 knots (17-31 mph), it doesn't really rival the thrust of some of its non-electric cousins (http://www.engadget.com/2006/06/01/aquada-maker-unveils-quadski-atv-jet-ski-combo/), but it's certainly fast and quiet enough for some reconnoitering or good old fashioned family fun. With four racks of Li Fe PO4 high capacity batteries, the motor powers a water jet turbine drive system to cut through waves without any sound pollution. Unfortunately, zipping around on electric power doesn't come cheap -- at €7,290 (or $9,939), it'll probably only appeal to those who also own the lake needed to enjoy it on. But hey, at least you've got until Q1 2012 to save up!
The EXO is similar in concept to the Silveira Group's Green Samba (http://www.gizmag.com/green-samba-first-viable-electric-pwc/15141/), a prototype electric watercraft that riders were intended to crouch/kneel on the back of - unfortunately the company now appears to be out of business, or at the very least has no current website.
Unlike the Green Samba, which was clearly aimed at adrenaline junkies with a reported top speed of 65 mph (105 km/h), the EXO is intended more to provide yacht owners or renters at water parks with relatively gentle fun - it maxes out at 31 mph (50 km/h).
The EXO is available in a reinforced ABS model (which comes in a choice of four colors), or a snazzy-looking carbon fiber version. The ABS weighs in at 29 kilograms (64 lbs) without batteries, while the carbon tips the scales at just 19 (42 lbs). The addition of either four or six racks of lithium iron phosphate batteries bumps those weights up by 20 and 30 kilos (44 and 66 lbs) respectively.

THE ORIGINAL MOTORIZED PRODUCTION SURFBOARD - THE JETBOARD
Originally conceived by Alfred Bloomingdale, heir to the Bloomingdale Department Store fortune, who liked to surf, but didn’t like to paddle. The prototype was made of wood but didn’t hold up. This one, constructed like the wing of an airplane was manufactured here in Los Angeles. It’s hard to find one for sale, as most end up in surf museums.
The speed of the board is controlled by the dial on the side. The leash connects to the board with a magnet, so if the surfer takes a spill, the leash detaches and kills the engine. It also has a convenient carrying handle. Everything is original including the paint and logo.
Dimensions: 10’10″ L x 26″ W x 5″ D

Just when you thought you had the original, you discover it was already done.. 40 years earlier!
Here's one from Vintage Projects:
'THERE'S something new in water-sports equipment — a motor-driven paddle board. It combines the common characteristics and seaworthiness of the surfboard and paddle board, but, more than that, it's power driven by a conventional outboard motor.
That's the new angle. Smooth, sweeping "hull" lines, crowned deck and low motor hatch make this the sleekest, trimmest little craft you ever looked at. Light enough to be easily launched by one person, it rides rough water like a cork.
http://www.vintageprojects.com/boats/motor-board-2-150.jpg (http://www.vintageprojects.com/boats/motor-board.pdf)The hull, or board, itself is constructed just like the nonpower jobs, except that it is 5Vi in. deep instead of the usual 3 in. or so on the conventional surfboard and paddle board. Deck and outboard plan views shown in Fig. 3 give the general over-all dimensions.
Note that the motor hatch is placed well forward, giving ample room for a tall man to lie full length aft of it. Controls consist of tiller and speed lever, and a clear plastic transom permits a view inside the "engine room" from the rear.
This, together with a midget headlight, could be lighted from a small storage battery for night cruising....'

<!-- Description -->Description:
<?BRFSUM description="Brief Summary" end="lead"?>BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the general art of powered vehicles, and to the particular field of surfboards and skateboards.
2. Discussion of the Related Art
Surfboarding and skateboarding require common skills of balance and agility. The surfboard is powered by movement of water supporting the surfboard and the skateboard is powered by the rider. In both cases, the rider cannot fully concentrate on balance and agility because he or she has to direct a significant amount of concentration on the powering of the vehicle.
Therefore, there is a need for a surfboard/skateboard vehicle that does not require a rider to divert a significant amount of attention to powering the vehicle.
While the art does contain several examples of powered surfboards, the power units associated with these surfboards are not positioned to enhance the balance of the vehicle. Such powered vehicles are not amenable to racing or competition because they are not properly balanced.
Therefore, there is a need for a surfboard/skateboard vehicle that is balanced so it can be used in competition and/or at high speeds.
PRINCIPAL OBJECTS OF THE INVENTION
It is a main object of the present invention to provide a surfboard/skateboard vehicle that does not require a rider to divert a significant amount of attention to powering the vehicle.
It is another object of the present invention to provide a surfboard/skateboard vehicle that is balanced so it can be used in competition and/or at high speeds.
SUMMARY OF THE INVENTION
These, and other, objects are achieved by a vehicle that is powered by a motor that is located on a body member of the vehicle in a position that balances the vehicle. The vehicle can be either a surfboard or a skateboard. The body member of the vehicle is also shaped so the motor unit of the vehicle adds to the balance and control of the vehicle when the vehicle is operated at high speeds or under competition conditions.
<?BRFSUM description="Brief Summary" end="tail"?><?brief-description-of-drawings description="Brief Description of Drawings" end="lead"?>BRIEF DESCRIPTION OF THE DRAWING FIGURES
FIG. 1 is a perspective view of a powered surfboard embodying the present invention.
FIG. 2 is a perspective view of a powered skateboard embodying the present invention.
<?brief-description-of-drawings description="Brief Description of Drawings" end="tail"?><?DETDESC description="Detailed Description" end="lead"?>DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Other objects, features and advantages of the invention will become apparent from a consideration of the following detailed description and the accompanying drawings.
Referring to FIGS. 1 and 2, it can be seen that the present invention is embodied in a water vehicle 10, such as a surfboard, shown in FIG. 1 or a land vehicle 10′, such as a skateboard, shown in FIG. 2. Both of the vehicles, 10 and 10′, have certain components which are identical to each other. Therefore, the initial description will be presented for these common components and reference can be made to either FIG. 1 or FIG. 2. The components that are different for the water vehicle 10 from the components associated with the land vehicle 10′ will then be discussed. Therefore, it will be understood that, while the following discussion initially focuses on FIG. 1, the common components will be found in FIG. 2 as well.
As shown in FIG. 1, vehicle 10, like vehicle 10′, comprises a body member 12 which has a front end 14, a rear end 16′ and a longitudinal centerline 18 which extends between the front end 14 and the rear end 16 of the body member 12. The body member 12 also includes a first side 22, a second side 24, and a transverse centerline 26 which extends between the first side 22 and the second side 24.
A first surface 30 forms a top surface 30 when the body member 12 is in use and a second surface 32 forms a bottom surface 32 when the body member 12 is in use.
The body member 12 is oblong in shape and the longitudinal centerline 18 is longer than the transverse centerline 26 whereby the longitudinal centerline 18 forms the major axis and the transverse centerline 26 forms the minor axis of the oblong shaped body member 12. The body member 12 can be formed of any material that is suitable for such vehicles, including plastics-type materials, composite-type materials or the like. Since the vehicle 10, 10′ may be used at high speeds, the materials are selected accordingly.
A longitudinal center portion 40 is located on the longitudinal centerline 18 midway between the front end 14 of the body member 12 and the rear end 16 of the body member 12, and a transverse center portion 42 is located on the transverse centerline 26 midway between the first side 22 of the body member 12 and the second side 24 of the body member 12. As shown in FIG. 1, the longitudinal center portion 40 is coincident with the transverse center portion 42.
The body member 12 is curved between the front end 14 and the rear end 16 to be concave when viewed from the top surface 30 and to have a radius of curvature R (see FIG. 2).
A motor unit 50 has a housing 52 mounted on the top surface 30 of the body member 12 immediately adjacent to the rear end 16 of the body member 12. A motor 54 is located in the housing 52 of the motor unit 50. The motor 54 can be any form suitable to the land vehicle 10′ or the water vehicle 10. The motor 54 can be an internal combustion engine, or, in the form shown in FIG. 1, an electric motor. The location of the motor unit 50 on the rear end 16 of the body member 12 co-operates with the curvature of the body member 12 to provide proper weighting to the body member as the body member 12 changes its position, especially a surfboard in the water, when the body member 12 is operated at high speeds. The location of the motor unit 50 provides stability to the body member 12 to permit the rider to have great control of the body member 12 when the body member 12 is executing complicated maneuvers, especially at high speeds, as will occur during competitions.
An on/off switch 56 is located on the housing 52 of the motor unit 50, and a key lock 58 is connected to the on/off switch 56 to disable the on/off switch 56 when the key lock 58 is in an “off” position. A “motor on” indicator light 59 is located on the housing 52 of the motor unit 50.
A power source 60, such as a battery pack, is located in the housing 52 of the motor unit 50 and is connected to the motor 54 via the on/off switch 56 when the on/off switch 56 is in an “on” condition.
A hand-held control unit 70 is associated with the motor unit 50 and has an electrical connection 72 to the motor 54 and a plurality of control buttons, such as on/off button 73 thereon. Other control buttons can control the speed of the motor 54, the direction of the vehicle 10, 10, and the like.
A motor barrier 76 is positioned on the top surface 30 of the body member 12 between the housing 52 and the motor unit 50 and the transverse center portion 42 of the body member 12.
Referring to FIG. 2, the land vehicle version 10′ of the vehicle embodying the present invention includes a chassis unit 80 located on the bottom surface 32 of the body member 12. The chassis unit 80 has a wheel mount frame 82 which includes two rails 84 and 86 which are mounted on the bottom surface 32 of the body member 12. The two rails 84, 86 are identical and are co-extensive. Thus, while only one rail is visible in FIG. 2, it will be understood that the other rail is identical to the rail visible in FIG. 2. Each rail of the two rails 84, 86 has a forward end 87 located near the front end 14 of the body member 12 and a rear end 88 located near the rear end 16 of the body member 12. The rails 84, 86 extend in the direction of the longitudinal centerline 18, and the longitudinal centerline 18 of the body member 12 is located midway between the two rails 84, 86.
A front axle 90 extends between the two rails 84, 86 in the direction of the transverse centerline 26 of the body member 12. The front axle 90 is located near the forward end 87 of each rail of the two rails 84, 86.
A rear axle 92 extends between the two rails 84, 86 in the direction of the transverse centerline 26 of the body member 12. The rear axle 92 is located near the rear end 88 of each rail of the two rails 84, 86.
Two front wheels, such as front wheel 94, are mounted on the front axle 90, and two rear wheels, such as rear wheel 96, are mounted on the rear axle 92.
A power connection 98, such as a universal joint or like element familiar to those skilled in the art of vehicles, is located between the motor 54 and the rear wheels 96 to drive the rear wheels 96 when the motor 54 is activated.
Vehicle 10′ is used in the manner of a skateboard.
Referring to FIG. 1 it can be seen that the present invention is also embodied in water vehicle 10. Water vehicle 10 has elements which are identical to the elements just described.
Vehicle 10 includes a propeller unit 100 located on the bottom surface 32 of the body member 12. Propeller unit 100 includes a housing 102 on the bottom surface 32 of the body member 12 immediately adjacent to the rear end 16 of the body member 12. The location of the housing for the propeller unit 110, like the location of the housing 52 for the chassis of the land vehicle 10′, co-operates with the location and weight of the motor housing of the vehicle to is add balance to the vehicle, especially during high speed and/or complicated maneuvers.
Two propellers 106 and 108 are located on the housing 102 of the propeller unit 100. Each propeller 106, 108 is located outside of the housing 102 of the propeller unit 100 and each propeller 106, 108 includes a drive shaft, such as drive shaft 110, which extends through the housing 102 of the propeller unit 100. The longitudinal centerline 18 of the body member 12 is positioned between the two propellers 106, 108 of the propeller unit 100.
A power connection 112 is located in the housing 102 of the propeller unit 100 and connects the shaft 110 of each propeller 106, 108 to the motor of the motor unit to rotate the shafts of the propellers-when the motor is activated. The power connection 112 is familiar to those skilled in the art. Since the particular form of power connection 112 does riot form part of the invention and any suitable power connection can be used in either vehicle 10 or vehicle 10′, the details of such power connections will not be presented.
Both vehicles can include safety straps and the like if desired.
It is understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangements of parts described and shown.

REMOTE CONTROLLED PERSONAL WATERCRAFT
Referred t as Robotic Jetskis
THE BLACKFISH Circa 2011
When it comes to protecting our shores, we have the Navy to thank for that, for being the first line of defense against any attacks from the sea. However as high-tech as our cruisers or submarines may be, there are times where lone divers or small watercrafts may very well escape detection which could spell trouble. Apparently this has been an issue the Navy has been facing up until now, and this is where the new “Blackfish” comes in.
The Blackfish is essentially a 10-foot long remote-controlled jet ski that is currently being tested by the navy. Its purpose is to respond to small watercrafts or swimmer who may otherwise get by undetected by the Navy’s equipment found on their bigger vessels. The Blackfish utilizes underwater sonar, surface radar and a video camera in order to monitor the waters and the surroundings, and since it can be operated up to a mile away, this should give allow the Navy sufficient time to react to any situation that may pop up.
Unfortunately (or fortunately) it does not come equipped with any sort of weapons, so I guess its purpose leans more towards surveillance rather than taking out the enemy.

REMOTE CONTROLLED "EMILY" LIFEGUARD BUOY
Rescue Buoy is manufactured by an Arizona based company called Hydronalix. The remote controlled rescue buoy has the capability of 518 minutes of patrol at 5 miles per hour. The rechargeable battery is 577 watt/hours, at Sleep Mode, you could reserve the EMILY rescue buoys battery power more than 100 hours. The EMIPLY weighs 25 lbs. and the rescue craft has a dimension of 54 x 16 x 8 inch LxWxH.
For a swimmer, EMILY’s shore-based operator is able to communicate with them via an onboard camera and two-way radio system – on one version of the product, at least. From there, it can transport the swimmer back to shore under its own power or, if a rescue line was attached when it set out, it can be towed back using that line. Aside from getting to those in need faster, sending EMILY to the rescue means that no more people are put in danger – a common problem for rescuers dealing with panicking swimmers.

AGUSTA BENELLI 400 HP
MV Agusta, a very famous old motor bike brand, in 2007 built a jet ski model very similar at the waveblaster but much powerful, but after his presentation, no more news.
December 21, 2007 The Personal Watercraft (PWC) market is in the grip of a horsepower “arms race” with a rash of new machinery announcements including a 342 bhp 2.2 litre V6-engined PWC from Austrian company HSR-Benelli (http://www.hsr-benelli.com/) and a 308 bhp 2.2 litre V8-engined PWC from the famous Italian MV Agusta motorcycle company (http://www.mvagusta.it/). It all appears to have been catalyzed late last year when Kawasaki announced its 250 bhp Ultra 250X (http://www.gizmag.com/go/7006/) into a market where Seadoo’s 215 bhp RXP was previously the fastest of the bunch. Subsequently, SeaDoo has announced 255 bhp RXP-X (http://www.sea-doo.com/en-US/Products/Watercraft/Musclecraft/RXP-X/)and RXT-X (http://www.sea-doo.com/en-US/Products/Watercraft/Musclecraft/RXT-X/) models, Honda has announced a turbocharged 1500cc Aquatrax (http://powersports.honda.com/2008models/#Aquatrax) and Yamaha has announced (http://www.waverunner-fan.com/products/08models/fxcsho/spec.html) a new lightweight purpose-built, turbocharged and intercooled 1812cc Super High Output (SHO) motor in its 2008 range. Given the radical upsurge in power outputs, one wonders what might be available a year or two from now.
Until Kawasaki announced its Ultra 250X (http://www.gizmag.com/go/7006/) last year, the most powerful standard PWC available was Seadoo’s 215 bhp RXP (http://www.sea-doo.com/en-US/Products/Watercraft/Musclecraft/RXP/) and a gentleman’s agreement with the US Coast Guard by all manufacturers meant that no stock PWC could exceed 65mph.
It all sounds like a remake of the motorcycle horsepower wars of the seventies and eighties which were catalyzed by Kawasaki with the release of the 82 bhp 900cc Z1 in 1973 (http://www.khi.co.jp/mcycle/museum/z1/history/index_e.html) – a landmark motorcycle with significantly more power than anything that had existed before.
The massive success of the Z1 saw the other manufacturers follow suit, and like bidders at an auction, Honda, Yamaha, Suzuki and Kawasaki continuously leapfrog each other with ever-more-powerful models, boosting top-of-the-line power to more than 100 bhp before the turn of the decade, 130 bhp by the mid eighties and 150 bhp by 1990. In 17 years, the horsepower of the leading mass-produced flagship models more than doubled. By comparison, in the subsequent 17 years, horsepower of the leading sports machinery has risen only 30%.
The parallels with the motorcycle industry are many – three of the four leading PWC manufacturers (Japanese makers Honda, Yamaha and Kawasaki) produce motorcycles also, and the engines used in PWC are often derived from motorcycle engines with Kawasaki’s Ultra 250X based on the ZX1400 bike engine and Yamaha getting great value in PWC from its R1 sports bike motor. The links grew stronger in the last few months with the news that the revered Italian motorcycle names of MV Agusta and Benelli are set to grace two new ranges of extreme performance PWCs.
Europe’s only PWC manufacturer, Austrian-based Hydrospace, acquired Benelli Motori (the engine arm of Benelli Motorcycles (http://www.benelli.com/)), changed its name to HSR-Benelli in October and announced an entirely new series of PWC at Salon Nautique de Paris earlier this month, all powered by derivatives of the Benelli Tre motorcycle engine.
Then MV Agusta unexpectedly unveiled the F4 Interceptor - a carbon fiber hulled V8-engined PWC - at the Milan Motorcycle Show in Italy a few weeks ago.
Interestingly both of the new European PWC manufacturers have opted to use large-capacity normally-aspirated powerplants borrowed from motorcycles, rather than the turbo/supercharged route of the Japanese manufacturers. Indeed, for their flagship models, both of the Europeans have taken motorcycle engines and created new engines by fusing two motorcycle engines together
MV Agusta has taken two of its high performance 1078cc four cylinder engines and created a Swiss-watch-like 2156cc V8 powerplant which will power a limited-edition 308 bhp, carbon-fiber–hulled, two-seater called the F4 Interceptor.
Information on the Italian machine is scarce though you don't need to be a Rhodes Scholar to recognize it is likely to become the world’s fastest and most expensive PWC and the ideal accessory for all those EUR100 million yachts moored in the Mediterranean.
The only information apart from the raw numbers available on the craft at this stage is that it has a CDI ignition, electronic fuel injection, a 3-blade stainless steel impeller, uses a 160mm high pressure axial flow pump and is claimed to weigh in at an astounding 238 kg dry.
Indeed, the specifications of the MV Agusta appear to hold the key to the machine’s performance aspirations. The light weight is not just a function of exotic materials such as the carbon fiber hull and frightfully expensive titanium and magnesium which is spread liberally around their motorcycles – it is also much smaller than any of the current crop. At 2.946 metres long, it is 36 cm shorter than the SeaDoo, which is shorter than any of the Japanese models – for those who can’t think in metric, that’s more than a foot shorter than any of the others.
As with any other form of performance motorsport, fundamental physics still applies - modest dimensions means less mass to accelerate, stop and change direction.
Compare the dimensions and power of the MV Agusta and HSR-Benelli to the recently announced offerings of the existing manufacturers and you’ll see a significant gap in the power-to-weight ratios – see this table (http://www.gizmag.com/the-400-horsepower-pwc-cometh/8555/picture/40783/) – and why we think the European PWC will naturally fall into an elite class of PWC similar perhaps to the difference between luxury class cars such as BMW and Mercedes, and their exotic automotive counterparts such as Ferrari, Lamborghini et al.
One of the most successful motorcycle racing marques in history (http://www.mvagusta.it/_vti_g2_hist1.aspx?rpstry=23_), MV Agusta produces a range of exquisite performance motorcycles including the world’s fastest production motorcycle (the F4 R312) and the world’s most expensive (the 100,000 Euro F4CC).
Limited numbers of the new F4 Interceptor will be produced in 2008 and no price has yet been announced but given its impeccable heritage and positioning as a luxury brand, it is expected to quite comfortably become the most expensive production PWC yet sold.
The new HSC-Benelli Series-R range will have four models, two using the three cylinder Benelli motorcycle engine (a EUR 11,250 Naked Edition tuned to 142 bhp and a EUR 13,500 172 bhp Pro Edition) and two using the V6 engine created by fusing two three cylinder engines together. The V6-engined machines will be a 278 bhp, 328 kg EUR 17,900 Prestige model and a 342 bhp EUR 19,900 race edition.
Given the conversion rates to US dollars, the HCS-Benelli Series-R range is likely to be very expensive in comparison to its contemporaries in the United States, though given the level of specification, many consider that the race machinery is indeed still a bargain.
There’s one other issue still to be resolved before the Series-R range makes an appearance in the lucrative U.S. market and that’s that the machinery has yet to gain U.S. Coast Guard approval – something which might be problematic given that the V6-engined machinery is likely to easily contravene the agreement between the manufacturers and the Coast Guard that no standard PWC will exceed 65 mph.
Where it all goes from here will be interesting. The aftermarket accessory market for PWCs is booming and an unlimited budget for go-fast goodies can build you a 90 mph PWC from the current crop of machinery.
Both the Benelli 1100 and MV Agusta F4 bike engines are capable of producing incredible performance with off-the-shelf parts. For example, the more expensive motorcycle variants of the MV Agusta F4 1078cc engine (such as the 2008 “312” model) produce in excess of 200 bhp. Benelli is rumored to be close to announcing a turbocharged version of its TRE with more than 200 bhp on tap.
Accordingly, 400 bhp is achievable from both the Italian V8 and Austrian/Italian V6 using readily available parts. 400 horses in a jet ski is a tantalizing prospect to be sure … and this is just the start.

Yves Mandar est un aviateur, un amoureux des motocyclettes, des belles mécaniques, de la vitesse et du sport. Dès la fin de ses études, au milieu des années 50, il est un des premiers à se pencher sérieusement sur la possibilité de retrouver les sensations de conduite d’une motocyclette, surfant sur les eaux, en développant ses motos nautiques. Depuis un siècle, des tentatives avaient été réalisées, bricolages associant des flotteurs divers ... skiff de bateau, mais aussi bidons vides, avec des roues à aubes mues par la force humaine ou par un moteur. L’ensemble, baptisé d’un nom pompeux (podoscaphe apparu dans les années 1880, Amphibocycle navigant sur la Seine en 1909, Hydron, appareil à suspension élastique, …), relevait plus de l’utopie créatrice exploitant un effet d’annonce que du véritable effort de création pour reculer les limites du possible pour l’être humain.

Le 9 octobre 1952, un de nos plus grands champions moto, Georges Monneret, Jojo La moto, traverse la Manche, sur sa Vespa amphibie, un scooter sur un bricolage de pédalo, prudent….sous l’escorte constante du bateau de pêche le Saint Joseph. Le scepticisme reste de rigueur.
L’immédiat après-guerre connaît pourtant une frénésie de développement de véhicules spéciaux, hybrides de voiture + bateau (Amphicars, environ 4 000 construites entre 1961 et 1965 propulsées par un moteur Triumph) avion + bateau (aéroglisseur, Hovercraft), avion + auto (Pou du ciel) , train + avion (Aérotrain Jean Bertin) , qui seront fabriqués en série, et mis en service.

</TH><TD class=style16>Aérotrain expérimental Jean Bertin N° 2
</TD><TD class=style16>Son contenu technologique
A cette époque, Yves Mandar aborde le problème de la "moto nautique" avec une démarche technique rigoureuse, cherchant à reproduire au plus près les sensations du pilotage d’une moto, mais sur l’eau, en développant un engin léger, performant et très homogène. Son expérience de pilote, sa connaissance de l’aérodynamique, lui permettent de transposer son savoir aéronautique sur la portance de l’eau et d’explorer le comportement d’une "moto nautique".
Entre 1954 et 1966, il va développer, seul, sans aucun soutien, 6 machines, numérotées MN1 à MN6. De la MN01 à la MN05 (photo ci-dessus) chaque moto nautique récupère le meilleur de sa devancière, qui, après réalisation et essais se voit démontée, disséquée, analysée et améliorée pour un modèle plus performant.
Le dernier modèle fabriqué est la MN05, présentée dans cet article, unique survivante que l’épouse de Yves Mandar, récemment disparu, m’a confiée pour lui trouver une destinée.
La MN06 ne dépasse pas l’état de projet papier et Yves Mandar, absorbé par ses autres activités professionnelles, et lassé du scepticisme autour de ses inventions, a abandonné ce développement, après le dépôt de ses derniers brevets en 1967 et 1968. Tous les groupes industriels qu’il a contactés à cette époque ne l’ont pas épaulé, mais ont seulement entrevu dans ses idées au mieux la possibilité d’utiliser la moto nautique comme un engin publicitaire, une espèce de folie attirant le public, pour faire vendre des sodas, ou populariser des marques…
Pourtant, après 10 années de développement, en 1966, Yves Mandar était bien près du but ! En 1977 James Bond utilise une moto similaire dans le film “l’espion qui m’aimait”.
<TABLE width=826><TBODY><TR><TD width=467 scope=row>Encore quelques années, et Canadiens et Japonais se saisissent de l’idée et développent la commercialisation à l’échelle du globe des Wet bikes, des jets-ski, et autres scooters des mers génériquement regroupés dans les PWC Personal WatercCrafts. Le marché mondial explose alors.
Les machines américaines et japonaises semblent avoir été inspirées des recherches d’un Californien, Clayton Jacobson, qui, comme Yves Mandar, avait développé des concepts de même nature, seul dans son coin. Ses machines sont toutefois différentes de celles de Yves Mandar : le guidon ne tourne pas ; la direction se fait exclusivement en se penchant... Ses inventions lui seront reconnues, après des années de procès, et finalement une transaction (c’était un avocat) contre de grands groupes qui s’en étaient approprié les retombées commerciales. Et aujourd’hui les Wet bikes et Wave runners de Suzuki et Kawasaki, constructeurs moto, ont tiré les bénéfices de ce marché aux cotés du Seadoo de Bombardier (un autre acteur du monde de la moto, avec sa filiale Rotax fournisseur de moteurs pour BMW F650, F800 , …)
<TABLE width=826><TBODY><TR><TD width=557 scope=row>http://www.cmc-retronautisme.fr/image/MN05%208.jpg
Pourtant ces machines sont beaucoup plus pataudes que celles de notre inventeur, avec leurs skis très larges et leur coque abaissée; elles ont sacrifié la légéreté et l’agilité aux exigences marketing de fournir 2 places, un démarrage électrique, et si possible de préserver leur pilote du ridicule de la gamelle. Bref, elles ont séduit le marché avec des arguments marketing auxquels Yves Mandar ne se serait pas soumis, lui à la recherche des meilleurs rapports poids / puissance, performance / maniabilité, …
GENESE d’une INVENTION
Revenons à l’époque des pionniers, celle où Yves Mandar marie sa passion de l’aéronautique à celle de la recherche des sensations du ski nautique et de la moto. En 1956, à 25 ans, il vient de finir des études d’aéronautique, et profite du Paris existentialiste avec son frère Serge et son complice du lycée Stanislas, Antoine Psalty. Tous trois, l’imagination enflammée par le dynamisme ambiant, et l’évocation d’un Oncle de Yves qui courait en Bugatti dans les années 30, pilotait son zinc, se passionnent pour les engins motorisés. La chambre de bonne du Boulevard Montparnasse est leur base, pour planifier leur participation à des courses automobiles, des courses de bateaux, aux manifestations aéronautiques … et pour imaginer brusquement en 1956 l’idée d’un moteur monté dans une carlingue et permettant de surfer sur l’eau.
<TABLE width=826><TBODY><TR><TH width=271 scope=row>http://www.cmc-retronautisme.fr/image/MN05%2010.jpg</TH><TD width=243>http://www.cmc-retronautisme.fr/image/MN05%2011.jpg
Des moteurs et des pièces sont achetées ou récupérées ; la chambre de bonne se voit équipée d’une petite fonderie à la cire perdue pour fabriquer des pièces en alu spécifiques, au risque de propager un incendie à plusieurs reprises dans l’immeuble. Quand les moyens financiers manquent pour acheter un outil, nos compères achètent les composants et se le fabriquent, comme un poste à souder acétylène par exemple. Petit à petit, les engins construits avec ces pièces repassent par l’escalier de service, et rejoignent des plans d’eau des boucles de la Seine, souvent des sablières, pour des essais les plus discrets possibles de flottabilité, d’étanchéité, de portance, et de performances.

Ces essais et cette période de développement vont durer 10 ans, au cours desquels des brevets seront déposés à partir de MN04 et surprise,… la Préfecture de Police moins pointilleuse qu’aujourd’hui, délivrera en 1966 un permis de naviguer à Yves Mandar, pour tester ses prototypes :
Se rendent-ils bien compte de ce qu’ils font ?
Parce que les premiers modèles présentent les risques inhérents à toute invention, mais là les réactions des engins sont inconnues et l’hélice et les dérives présentent des dangers réels, même si les essais se font dans des lacs, sur des eaux plates, dégagées de tous baigneurs et autres obstacles.
Il faut se figurer le premier déjaugeage, perché sur une forme de moto à 1,40 m de la surface de l’eau, sur un engin de 150 Kg, que personne n’a jamais imaginé, mu par un moteur à hélice de 35 CV quand même.
Les chutes au « bouillon » sont fréquentes, par mauvais déjaugeage, par éjection, par zig zag trop serré, voire par peur d’arriver trop fort sur la berge.. les essais de 15 minutes environ sont consignés dans une fiche de résultats.
Le démarrage est précédé du pointage d’une check list, le même rituel que dans l’aéronautique, car là aussi, il s’agit d’éviter de partir avec le trou de vidange de coque ouvert ou le capot mal verrouillé; Comme dans toute démarche innovante, on apprend de ses erreurs, et les moto nautiques sont progressivement équipées de systèmes de sécurité (coupe circuit par boucle reliée au poignet du pilote, système de pressurisation du réservoir réalisé avec une valve de chambre à air de vélo, adjonction d’une forme de quille, amortissement par un ressort des vibrations du ski dues au franchissement de vaguelettes,…
La science progresse à la sueur de nos pilotes d’essais qui vont petit à petit faire progresser la conception de l’engin, avec pour seuls secours en cas d’incident : une pagaie, un masque de plongée et des pansements.
Les premiers essais de MN01 à MN04
Nous n’avons plus de traces des MN01 à MN03, mais il nous reste des photos et un des deux carburateurs de MN03. Toutes ces machines partageaient avec la moto une forme de coque protégeant l’appareillage et le moteur, avec une selle que le pilote chevauche, agrippé à son guidon, dans une position très proche du motocyclisme classique

<TABLE width=826><TBODY><TR><TD width=397 scope=row>La grande différence vient de l’absence de roues, qui sont remplacées par 2 skis nautiques en aluminium, disposés l’un derrière l’autre, actionnés depuis le guidon par les leviers usuellement dévolus au frein et à l’embrayage. Les genoux du pilote enserrent le réservoir et participent au pilotage, comme en moto.
Il n’y a pas d’amortissement, mais un réglage par palonnier de l’angle d’incidence du ski avec la surface de l’eau
Les photos montrent une architecture de MN03 très inspirée de celle d’une moto de l’époque : deux moteurs thermiques de moto (Ydral 2T ?, cylindrées ? à culasse Maucourant) sont enserrés dans un cadre double berceau en acier, surmonté d’un réservoir d’essence prolongé d’une selle. Les moteurs transmettent son mouvement à une hélice placée sous le ski arrière.

Sur certaines ébauches, MN03 est équipée d’une selle capitonnée avec dosseret arrière, à la chopper.
Le centre de gravité est bas, mais l’emplacement des moteurs impose de les protéger contre les entrées d’eau, donc de les caréner de manière étanche ; cet habillage pose des problèmes de refroidissement. La transmission à l’hélice se fait vers l’arrière, par une ligne d’arbre.
Ces fondamentaux semblent bons : MN03 pose des problèmes probablement de flottabilité et d’étanchéité, mais surtout de direction ; le poids du pilote ajouté au lest arrière des moteurs, décharge l’avant qui n’est pas assez directif lorsque la moto déjauge. Cette disposition, favorable pour les décollages, est catastrophique lorsque le pilote perd le contrôle de son engin, qui part en vrille dans l’eau. Quand il arrive à la maintenir, notre pilote indique que la machine oscille dans des mouvements de «galop».
Insatisfait, Yves Mandar va développer la MN04, en remontant le moteur à l’intérieur de la coque de protection, et en abandonnant les moteurs de motos pour un moteur de bateau refroidi par eau et équipé d’un arbre long. MN04 ci-dessous :
<TABLE width=826><TBODY><TR><TH width=299 scope=row>http://www.cmc-retronautisme.fr/image/MN05%2018.jpg</TH><TD width=219>http://www.cmc-retronautisme.fr/image/MN05%2019.jpg</TD><TD width=292>L’embase située à l’avant sert à la propulsion (hélice) au surf (support du ski) à la direction (rotation dans une bague spéciale), et le berceau forme une grande dérive assistée par des petites dérives sous les skis jouant un rôle de carres.
L’engin n’est pas très homogène.
Puis viendra la MN05 :
Son aspect général fait beaucoup penser au dessin des fuselages d’avions de l’époque. De même, l’arbre avant avec ses amortisseurs rappelle un train d’atterrissage d’avion. MN05 est vraiment la motonautique la plus aboutie et qui marche fort. Sa coque de fibre polyester armée surmoulée sur une poutre treillis, enveloppe un moteur hors bord conventionnel, dont l’arbre moteur rallongé traverse l’avant du motonautique ; un ingénieux système de paliers tournants étanches transmet une rotation du guidon à tout l’ensemble moteur, arbre, ski avant et hélice (Johnson 25 CV ou Evinrude 35 CV ?)
<TABLE width=826><TBODY><TR><TH width=494 scope=row>http://www.cmc-retronautisme.fr/image/MN05%2021.jpg
L’arbre du moteur descend à la verticale du guidon, l’embase et l’hélice traversent le ski avant et se voient entourés de deux dérives en alu formant carres, et permettant à l’avant d’être dirrectionnel. L’inclinaison des skis est contrôlée par les 2 leviers usuellement dédiés aux freins. Ici, pas de frein, malgré une vitesse élevée, estimée à bien plus de 50 km/h.
Comment çà marche ?
La plupart des véhicules marins antérieurs reposent sur le principe d’Archimède, la flottaison d’un corps qui reçoit la poussée verticale du volume d’eau déplacée, et qui se meut grâce à une hélice. MN05, elle, se meut à la surface de l’eau, avec un tirant d’eau quasi nul, grâce à sa vitesse après déjaugeage. La moto nautique, lors de sa mise à l’eau, s’enfonce jusqu’à sa ligne de flottaison, qui correspond à la décoration peinte en rouge sur ses flancs.

Le pilote est assis sur la partie arrière de la coque ; basculé en arrière, il se tient dans la position d’un skieur nautique, qui sort légèrement son ski avant de l’eau en tirant sur les câbles situés au guidon; il met alors les gaz, et à partir d’une certaine vitesse, il émerge de l’eau et bascule rapidement alors son corps vers l’avant pour assurer la liaison du patin avant sur l’eau.
Puis, il surfe, comme un skieur nautique, mais sans bateau , ni corde pour le remorquer. Il fait de l’aquaplanning comme un bateau de compétition pourrait le faire. Il prend les virages, en penchant son corps à l’intérieur, et en tirant sur le guidon opposé au sens du virage , tout comme lors de la conduite d’une moto, les skis et dérives prennent le relai des pneus. Seule la vitesse élevée tient la moto à la surface de l’eau. Les sensations sont extrêmes.

Pour s’arrêter, il faut soigneusement doser sa décélération en l’amortissant par des petits coups de gaz, au fur et à mesure de la redescente dans l’eau : à réaliser de préférence en ligne droite…

Mais il reste quelques problèmes à régler : c’est une traction avant !!
Il faudrait une propulsion, pour permettre de dissocier les fonctions de motricité, d’amortissement et de direction.
Ainsi, démarra la MN06
Yves Mandar pense maintenant à déplacer son moteur, son embase et arbre vers l’arrière du bateau. L’hélice placée sous le ski arrière, ne s’opposera plus à la rotation du guidon avant et donc à l’agilité de la machine.la direction, soulagée du lourd poids du moteur, devient plus précise. Surtout cette simplification du train avant permet d’y ajouter une suspension, comme sur une moto. Cette suspension pourrait alors amortir les effets indésirables des mouvements de l’eau, du marsouinage et assurer une meilleure stabilité de l’engin dans les courbes ; le seul contrepoids à l’avant reste le réservoir + le pilote.
Sur le plan technologique, Yves Mandar prévoit de réaliser la peau extérieure en résine synthétique armée de fibre de verre, en profitant du retrait inhérent à la polymérisation pour sceller dans la coque les douilles de fixation du moteur et des accessoires.

Diverses études de coques
Cette machine pourtant complètement dessinée, ne sera jamais fabriquée ; seul un brevet a été déposé à l’INPI.
Et Yves Mandar laissera là ses développements. Sa démarche aura été celle d’un aviateur. Je cite Saint Exupéry, qui écrivait dans ‘Terre des Hommes’ : "Il semble que la perfection soit atteinte non quand il n'y a plus rien à ajouter, mais quand il n'y a plus rien à retrancher." Cette philosophie est aussi celle qui nous a donné les motos les plus belles, les plus racées.
La MN05 fera sa dernière sortie à Saint Cloud le 1er Mai 1977, à l’Hélice Club de France, puis elle sera remisée pour un long sommeil jusqu’à Mars 2010. Elle y perdra au passage son ingénieux coffre ponton flottant qui permettait d’improviser une base de tests sur n’importe quel plan d’eau.
<TABLE width=826><TBODY><TR><TH scope=row>http://www.cmc-retronautisme.fr/image/MN05%2033.jpg</TH><TD>http://www.cmc-retronautisme.fr/image/MN05%2034.jpg</TD></TR></TBODY></TABLE>
Et pourtant le succès des motos des mers va venir d’une démarche opposée ; celle du rajout, de l’inflation d’accessoires, de gadgets, de puissance… qui me permettent aujourd’hui de dire que les MN étaient de vraies motos qui n’usurpaient pas leur titre ; d’ailleurs l’administration française me donne partiellement raison en qualifiant les autres machines de VNM Véhicules Nautiques à Moteur…
Donc, en 1975 le flambeau sera repris par les Canadiens d’Arctic entreprises, qui fabriquaient des motos-neiges, et qui souhaitaient équilibrer la saisonnalité de leur production par des motos nautiques.
Directement inspirée du moto neige, leur produit a un arrière traineau, beaucoup plus bas que les MN, ce qui permet de résoudre toute une série de difficultés comme le transport routier de l’engin, sa mise à l’eau via les rampes des ports (il flotte et son moteur est toujours hors d’eau) son déjaugeage (il ne faut pas sortir de l’eau), sa stabilité en course. Des cares sont placées sous les skis, mais l’ensemble dérape beaucoup sur l’eau, en restant beaucoup plus à plat que les MN, ce qui lui permet d’aller en mer, alors que l’usage des MN restait limité aux eaux plates des lacs et des rivières, sauf envie de se faire de grosses chaleurs, immédiatement calmées dans l’eau froide.
Les nouvelles machines sont équipées d’une turbine infiniment moins dangereuse que l’hélice, et les virages sont déterminés par l’angle du jet de cette turbine à l’arrière du bateau. Le démarrage est électrique, grâce à une batterie logée dans le coffre sous la selle. Le coffre est protégé des inondations par une pompe de cale. Un extincteur ( !) équipe même certains modèles. Le gabarit de la machine et sa stabilité permettent d’emmener un(e) passager(e), ce qui est un argument de vente incontestable.
Bref toute une série de compromis de nature « marketing ».

Centre de gravité abaissé, ski large, selle confort, turbine hydrojet, mais que l’engin semble pataud ! ces choix techniques de confort conduisent à un alourdissement considérable des engins. Les motorisations suivent, et les premiers wetbike arrivés en France équipés de moteurs Suzuki 50 CV bicylindre 2temps, alimentés par un réservoir de 30 litres de mélange, évolueront vers des machines actuellement motorisées à plus de 100 CV, capables de tracter un skieur nautique (sic !) Evidemment, les sensations sont infiniment moindres que celles des MN. Nous ne sommes plus dans le monde de la moto (malgré le nom donné en Français) mais dans celui du personal watercraft (PWC), un cousin du bateau, marié à un scooter plutôt qu’à une moto, dont le succès commercial va grandir.
Rapidement Kawasaki, Suzuki et Bombardier produisent des machines, avec des moyens financiers, qui n’ont plus rien à voir avec ceux de nos génies du début, eux qui ont pourtant posé toutes les bases du problème, en prouvant la faisabilité de l’Idée. Le succès commercial viendra au prix de compromis sur les sensations pures de la moto (vitesse, acuité, légèreté, …) que Yves Mandar ne voulait probablement pas sacrifier au confort et à la facilité. Il se vend 40 à 50 000 jets skis et autres scooters des mers de par le monde dans les années 80, puis le chiffre avoisine les 200 000 unités vendues chaque année dans la seconde moitié des années 90.
Ce succès commercial s’accompagne d’une course à la puissance, qui finit par atteindre plus de 100 CV sur certains modèles apparus dans les années 80.
Les produits et surtout le comportement de leurs pilotes génèrent de nouveaux dangers dans les zones de baignade ; près de 30% des accidents avec des baigneurs leur sont imputables, alors qu’ils ne représentent que 10% des embarcations. rajoutons le bruit, la pollution, le coté frimeur et on comprendra que les années 2000 ont été le point de départ de mesures répressives vis-à-vis des PWC et le début de la fin de l’engouement du public.
La boucle est bouclée.

La MN5 n’est pas une affaire qui rouille.

MOTO NATIQUE - MN
Yves Mandar was an aviator, motorcycle enthusiast and lover of speed and motorsports. Upon completing his studies in aeronautics in 1956 at the age of 25, he sought the idea of creating a motorcycle on the water. He along with his brother Serge, and assistant from High school, Antoine Psalty, worked together on their conceptual idea of surfing at speed on the surface of water.
They begin to acquire what performance products are readily available to piece together the idea. They cast parts out of wax casting they made in aluminum. Oftentimes they lacked the finances to develop parts. Their concerns on their design were lift, performance and waterproofing.
These tests went through a decade of corrections and design phases. During this time they filed patents on their designs. In 1966 Yves Mandar was issued a permit to test their prototypes.
On October 9, 1952 Georges Monneret, JoJo the motorcycle crossed the Channel on an amphibious Vespa under the escort of the fishing boat 'Saint Joseph'. This postwar era began a frenzy of special vehicle development now that the war machine had produced new technologies. Special vehicles a hybrid car/boat , an amphibious car was constructed, hovercraft. The amphibious discovery phase began.
Between 1954 and 1966 Yves produced 6 machines, numbered MN1-MN6. Of MN01 to MN05 each motor gets the best design increase from its predecessor. Upon completion of testing, a technical inspection commenced from a complete tear down to a re build to improve the next generational model. The latest model was manufactured MN05, was Yves Mandars wife who recently passed away.
The MNO6 does not exceed beyond a blueprint draft on paper. Yves was busy with other professional activities, tired of the skepticism surrounding his inventions, abandoned project. His last patent was filed in 1967 and 1968. He had contacted all the known industry groups at that time but gathered no interest, they merely took a glimpse at his ideas using it as a possible advertising vehicle for popular soda brands.
In 1966 after the initial decade of development on this project, Yves Mandar was closer. In 1977 James Bond used a similar device called the WET BIKE in the motion picture called 'The Spy Who Loved Me'.
Bombardier, Sea Doo and Japanese personal watercraft makes developed their own brands of personal watercraft. The original products that were mass produced were the Kawasaki JETSKI and the Wet Bike. The original SEA DOO watercraft of 1967 was designed by Clayton Jacobsen whom also designed the JETSKI watercraft.
In the article posted there are comparisons to the other products on the market, however the designs have similar concepts but are quite different in their rider position and capability. The Wet Bike and Yves machine being the most similar of all these designs.
The risks involved were inherent of their invention, gear, propeller and drifting with a dead or inoperable craft were real dangers. So their first tests were on lakes in flat water, clear of swimmers and other obstacles.
The machine was 150 kg of weight, driven by a propelled engine of 35 CV operated 1.40m from the surface of the water. Falls were common due to poor planing. Ejections were common by zig zagging too tight, or too much banking into a turn. They noted 15 minute tests on a scorecard.
The start was preceded on the score of their checklist, similar to the ritual conducted in aeronautics testing. Many mistakes were corrected over time. The electronics and seals proved difficult to waterproof. (circuit breaker connected to the wrist loop driver, tank pressurization system with a valve made of bicycle inner tube material, adding a keel shape, damping vibrations of a spring ski due to the crossing of wakes, and so on)
These three test pilots advanced their theories and designs. They started out with an emergency paddle for a dead 'boat' to get back to shore, a diving mask and bandages!
There are no artifices remaining of the MN01 to MN03, but only photos to review. One with two carburetors LV03. The riding design for the operator was similar to the body profile of riding a motorcycle. Tow aluminum skids similar to skis inline to one another and different sizes were part of the design, actuated one fro the handlebar levers by a brake and clutch. The driver's knees grip the tank and support the pilot. There is no true brake, but setting a rudder angle inline with the ski to the surface and balancing the body in conjunction with all these phases was required to stay in step with the craft. Balance points and forward momentum were needed.
The engines were enclosed in a double cradle steel frame, with an extended fuel tank in the saddle are of the seat. Under the seat is where the engine transmits its energy to the propeller directly located at the rear of the ski. The center of gravity is low, but the engine location is designed to protect it against water immersion. The inline drive shaft is the transmission to the propeller.
Buoyancy and sealing again were problems along with the rider's weight, ballast was added to the rear engine, front discharge so it would plane better. Trying to keep the craft on the surface of the water rather than airborne and porpoising was a concern, because the operator could easily lose control of the craft, causing it to spin in the water. The oscillation in movements create a 'gallop' effect and not a smooth open ride. On MN04 design development, the protective shell around the engine was further needed to waterproof. They abandoned the motorcycle engines and went to a boat engine that was water cooled and equipped with a longer shaft. The base is located at the front propeller, to support the front ski skid in the direction that it rotated properly. The cradle forms a large drift assisted by small drifts under the ski playing on the edges, or chines. The machine is not very homogeneous. Then comes the MN05.
It's general appearance was similar to its predecessors of aircraft fuselages of their time. This was the most successful powerboat and was much stronger. Her fiber reinforced hull made of polyester molds over a lattice girder, held a conventional outboard motor. The motor shaft extended through the front of the powerboat, an ingenious system of rotating sealed bearings transmits a rotation of the handlebar to the whole engine and the propeller. This was a 25 HP Johnson or Evinrude 35 HP)
The motor shaft descends to the vertical point of the handlebar, the base and the propeller cross the front of the ski and the two skis (fins) are surrounded by formed aluminum edges, allowing directional turns. The inclination of the skis is controlled by two levers dedicated as braking units, but at a speed of over 50 Km/h there were no true brakes.
They worked from the principle of Archimedes, buoyancy of body that receives vertical thrust of the volume of water displaces, and that moves through water with a propeller, this was the MN05. She moves through the surface of the water, with a near zero draft, due to its speed after lift-off. The water bike at its launching, while displaced would sink to the waterline, which corresponds to the painted red strike as a decoration on port and starboard, that was its true 'waterline' mark.
The operators sits on the rear of the hull, tilted back, they stand in the position of a water skiier, as the ski comes out of the water while they pull on the cables attached to the handlebars, they pull more throttle , as the speed increases the craft rises into a planing position and increased stability is ensured. Then the operator switches their riding into the sitting position.
The operator needed some training about unwanted 'wheelies', not having the proper trim of the craft, operators had to modulate the throttle and use proper body positioning, in a total adjustment while underway. Unsteady forward movement (velocity) generates the effect of 'galloping' with longitudinal oscillations of the bike, this is usually where falls occurred. They still had problems to solve. It would take them some time to solve and separate the functions of water traction, cushioning and directional control.
This led to the design changes of the MN06.
Yves Madar through to move the motor shaft and its base toward the stern of the craft. The screw under the rear ski, no longer opposed the rotation of the handlebars so the front end handling of the machines was easier. He adjusted the balance center in the craft design of the heavy engine. He simplified the front axle for suspension. This new suspension would dampen the adverse effects of hard movements against the surface of the water such as porpoising, and improve stability in sharp terns. Before this other only counterweight measures were the operators weight over the fuel tank.
Yves wanted to improve the outer skin of a synthetic resin fiber reinforced fiberglass, taking advantage of the polymerization shrinkage inherent to seal the hull in the engine mounting sockets and accessories. The motor and its shaft are passed to the rear, forward an air port is create. It was never manufactured, however a patent was filed with the INPI.
His approach to design has been that of an aviator. I quote from Saint Exupery, who wrote in 'Terre des Hommes': "It seems that perfection is reached not when there is nothing more to add, but when there is nothing to hide." This philosophy is also the one who gave us the best bikes, the more competitive machines that complimented speed and pushing the envelope.
The MN05 will be his last outing in St. Cloud on 1 May 1977, at the Propeller Club of France, then it will be stored for a long sleep until March 2010 when it is rediscovered. It will lose its ingenious way to safe floating pontoon which allowed to improvise a test database on any body of water.

Pedal Power. Before marine engines were made in small sizes, the bicycle and human effort were creating a curiosity.
In place of a paddle or oar for propulsion, the pedal cycle of a bicycle was being played with.. here is one version, although a bit 'unsteady and unstable, mounting and dismounting could be interesting. Probably not a great idea unless operated in calm waters.

The Amphicar is an amphibious automobile the first such vehicle mass-produced for sale to the public starting in 1961. The German vehicle was designed by Hanns Trippel and manufactured by the Quandt Group at Lübeck and at Berlin-Borsigwalde. Its name is a portmanteau of "amphibious" and "car". The Amphicar was designed to be marketed and sold in the USA. Compared to most boats or cars, its performance was modest, and only 4000 were produced by 1965. Nevertheless, it is still among the most successful amphibious civilian autos of all time, and still often prized and preserved as novelty collectible automobiles today

IN THE BEGINNING-PADDLE POWER TO PEDAL POWER TO MOTORS
Stand Up Paddle (SUP) use of powering canoes, dugouts, planks, boards has been one method of water transportation for thousans of years. Oftentimes relying on current, wind or weather patterns seasonally, and human effort on handmade dugout trees or planks of hand hewn wood. When the 1800's brought in the inventions of engine, steam and coal burning propulsion, the marriage between horsepower and manpower gap was being bridged!

The Baja Skimmer incorporates the stabilizing features of a traditional “V” hull and the drag reducing features of a tunnel hull. This combination gives the boat superior stability and handling qualities. Side boards and stub wings deflect all spray, keeping the occupants dry throughout their ride. This exclusive design has allowed us to develop a shallow draft craft, with a great deal of stability, that can operation in as little as 7” of water.
The true secret to the Baja Skimmer’s performance, though, is its Whisper Fan propulsion. For over a decade Trek Aerospace has been researching, developing and building advanced ducted propeller aircraft for the Defense Department. The sophisticated duct technology provides increased thrust at lower noise levels. Trek Aerospace has made that superior technology available to boaters.

MOTORIZED SKM BOAT - Motorized Surfboard
Circa 1951 a skim board type of boat with the motor inserted in the hull was listed for sale at .$25,000. Seems the owner thought he had an original concept that would be a museum piece. There are many of this 'one off's' created by enterprisising folks, but as far as museum pieces go, this novelty is one for the someone who has the desire to add it to the history books. I doubt it will sell at that value at this time as a no brand boat.
1951 SKIM BOAT
On display at the Antique Boat Museum in Clayton NY, was to be ridden sitting or standing.
It was advertised as a self propelled surfboard that was patented in 1936 by Emil Hansen in Media, Pennsylvania.
The Skim Boat was powered by a 7 1/2 Martin and steered by a small rudder or by the rider shifting their weight.

Plans: how to build motor driven paddle boat
Skim the Waves in this motor-driven paddle board.There's something new in water-sports equipment a motor-driven paddle board. It combines the common characteristics and seaworthiness of the surfboard and paddle board, but, more than that, it's power driven by a conventional outboard motor. That's the new angle. Smooth, sweeping "hull" lines, crowned deck and low motor hatch make this the sleekest, trimmest little craft you ever looked at. Light enough to be easily launched by one person, it rides rough water like a cork.
The hull, or board, itself is constructed just like the nonpower jobs, except that it is 5 in. deep instead of the usual 3 in. or so on the conventional surfboard and paddle board

What is a Wetbike?
The original Suzuki powered, 50 horsepower version of the Wetbike was introduced in 1978 by Spirit Marine, a division of Arctic Enterprises. Early advertisements marketed the product as the “Wetbike Watercycle”: A motorcycle on water with a combination of all the thrills and fun of motorcycling, boating and waterskiing. Throughout its production run, which lasted from 1978 through 1992, the Wetbike received various changes, up-grades, technical advancements, and additional safety features, the most notable changes being the introduction in 1985 of a strong, exceptionally lightweight Metton body unit and in 1986, the introduction of a 60 horsepower, 800cc Suzuki motor, which brought the performance of the Wetbike to the pinnacle level of being the fastest personal watercraft available at that time.
There are many personal watercraft produced today that reach speeds far in excess of those speeds that were achieved by the Wetbike. However, nothing found on the water today has the distinctive graceful appearance of a Wetbike or imitates the ride characteristics of all the freedom and feel of a motorcycle. Why? Because the Wetbike is the only personal watercraft that has front steering, producing an exhilarating feeling of turn carving maneuverability that no other watercraft can match. To achieve this, the Wetbike rises up on two skis to its planning position and then skims across the water as a hydrofoil watercycle. Precise cornering abilities and excellent handling characteristics are attributed to the “Hydro-Link” front suspension system, a uniquely responsive front steering system and skis that are hydro-dynamically designed, all combining to produce maximum turn carving ability and graceful maneuverability.
One time out on Wetbike is one time to remember. The watercycle sits squarely in the water. Get behind is, grasp the handles and get the feel. With one good skootch you should be able to slide up into the saddle. Keep your balance. Turn the electric start. And gently open the throttle.
The 50 h.p. Spirit jet drive magnificently propels you to the surface, water beads glistening in the sun. And it does it without any propeller. The jet stream of water is backed by 723 cc's of factory tested Spirit power. Plus reliable Mikuni carburetors, super efficient reed valves and low maintenance CD ignition. Enough power to ride single or two up. Or even to pull a water skier.
You handle Wetbike like a motorcycle. Lean into turns, respond to the feel and Wetbike responds right back. To come to a stop, ease up on the throttle and Wetbike settles gently into the water again. It does the same if you take a spill, with a safety tether switch and spring loaded "off throttle".
Wetbike launches anywhere boats can and even where boats can't It trailers and unloads just like a boat or wheels across the sand on the two wheeled Beach Buddy.

Franky Zapata: ‘Flyboard’ Water Jet Pack takes to the Air at Lake Las Vegas
With a quick squeeze of the throttle, Franky Zapata shot out across Lake Las Vegas Wednesday afternoon and began dipping and diving as he floated as high as 20 feet above the water using a specially built piece of equipment he calls a “flyboard.”
Zapata was showing off his patented invention to dozens of people who gathered to watch as part of a demonstration near the Montelago Casino at Lake Las Vegas.
The flyboard is powered by jets of water that are generated by a Sea-Doo watercraft and forced through a tube connected to a platform that Zapata straps his feet into. Zapata, a native of France, pilots the board by using his legs to alter the direction of the pressurized water jets, which allow him to perform a variety of aerial maneuvers, including flips, spins and a series of dives where he imitates a dolphin.
“It’s very easy, when you move your legs, you move you the water nozzle. It’s like snowboarding,” he said.
The invention was born earlier this year when Zapata, a professional watercraft racer, was testing new equipment and realized the motor created enough pressure to propel a person into the air.
After a bit of trial and error, and including additional hand jets that help stabilize him as he flies, Zapata’s device was complete and he began taking it around the world for demonstrations.
He plans to begin selling them in retail stores sometime this spring, including at the Proshop Motorsports and Marine store in Henderson. The boards are expected to cost about $5,000, watercraft not included, Zapata said, and will allow people to float 10-15 feet above the water.
The device is easy to pilot, he said, and it takes most people less than an hour to figure it out.
“It’s an amazing sensation. You can go fast and make a turn and it feels like you’re gripping on the air,” he said. “Every day I can’t believe it’s possible.”

KAWASAKI HEAVY INDUSTRIES (KHI)
Kawasaki Heavy Industries has come along way since it was founded in 1878 by Shozo Kawasaki. Today Kawasaki is a multi-national corporation with more than fifty holdings (manufacturing plants, distributions centers, and marketing and sales headquarters) in most major cities around the world.
Kawasaki Heavy Industries, Ltd. (KHI) is engaged in building transportation systems for the 21st century, and in doing so, is utilizing the wealth of technological know-how it has accumulated over the past 100 years. The ship building division has led the world in producing ever larger, ever faster, increasingly automated ships. It is constantly striving to find ways to increase ship manufacturing and navigation efficiency while conserving energy. So far, the quest has resulted in the development of Liquid Natural Gas (LNG) carriers, high-speed ships and other future-oriented marine technologies.
By applying aviation principles, a Jetfoil that speeds above the water at an amazing 45 knots is one project that has become reality. Kawasaki led Japan's shipbuilding consortium formed to build the Techno-Superliner. This exciting new vessel is planned to carry a payload of approximately 1,000 tons and travel at a cruising speed of 50 knots.
Kawasaki is supplying rolling stock for the world-famous Shinkansen bullet train as well as other trains. The company is now developing a next-generation Shinkansen that will travel at a top speed of 240 mph. Kawasaki's expertise extends well beyond simply the development and manufacture of rolling stock. As a systems integrator, Kawasaki engineers total railway transportation systems, from train operation control to rolling stock inspection and repair operations.
In the aircraft sector, Kawasaki is engaged in a broad range of activities as a manufacturer of both aircraft bodies and engines. At present, the company is manufacturing the Kawasaki-developed MBB K117 helicopter and portions of the latest passenger aircraft, the Boeing 777. Kawasaki is also an important player in the project to develop the Supersonic Transport (SST), a plane that will travel at altitudes of 60,000 to 90,000 feet at a speed of Mach 2.5 and will carry from 200 to 300 passengers. Kawasaki's high-speed transportation technologies also extend beyond the atmosphere of earth in the new quest to utilize space and its resources.
Kawasaki's civil engineering and construction machinery is contributing to the creation of new towns with its bridges and high-rise buildings. The success of the Eurotunnel, the large-scale project that links England to France, owes much to the two tunnel boring machines made by Kawasaki. The company also built the shield machines - the worlds largest, at more than 46 feet in diameter - for the construction of the Trans-Tokyo Bay Highway.
Bridge construction is another Kawasaki strength. The company recently completed a main tower of the Akashi Kaikyo Bridge. When completed, this will be the longest suspension bridge in the world.
Plus, Kawasaki is doing its utmost to fulfill its responsibilities to the planet by being environmentally conscious. It is making every effort to develop environment-friendly plants, technologies to protect the earth, new sources of energy that will help ensure a stable supply of resources and energy, and energy-conserving and recycling technologies.
The Combined Cycle Power Plant (CCPP), for example, uses lowpolluting natural gas to turn the turbines that generate power, while exhaust heat is used to generate additional electricity. Kawasaki's resource recycling system uses heat from city refuse incinerators to power coolers and heaters and to heat water; it also collects reusable resources from various types of refuse.
Other technologies, including water treatment, flue gas desulfurization and denitration plants, are also proving highly effective in the protection of the environment and the conservation of energy. Kawasaki is always monitoring future technologies and is well positioned to enter the era of fusion energy that will follow.
The Kawasaki name represents a technological enterprise whose activities range from large-scale, international projects to items used in daily life and for recreation. And at every step, Kawasaki pays the utmost attention to humankind and the environment. The past 100 years of innovation has enabled Kawasaki to establish a firm foundation as a leading technological enterprise. Now, the company is fully prepared to welcome the new century and looks forward to playing a leading role in the advancement of humankind and to another century of innovation.

<TABLE border=0 width=603 height=1><TBODY><TR><TD height=27 width=603>October 1st 1995</TD></TR><TR><TD height=77 width=603>Robert Overcracker rides a jetski over the brink of the Horseshoe Falls to help promote awareness for the homeless.
'SAVE THE HOMELESS'
His lack of safety awareness and preparation killed him. He did not put together a professional support team, it was a reckless and negligent operation.
He was operating a Kawasaki JETSKI TS 650 model. He was 39 years old and from California. Entering the Niagara River near the Canadian Niagara Power Plant, he started skiing toward the Falls. At the brink of the Falls, Overacker ignited a rocket propelled parachute that was strapped to his back. His plan was that the rocket would quickly deploy the parachute allowing him to safely land in to river below the Horseshoe Falls where he could be rescued. Overacker did ignite the rocket which deployed the parachute as planned. Unfortunately as the parachute deployed it fell away from Overacker to the ground below. Unknown to Overacker the parachute was not tethered to his body.
The parachute was not packed by Overacker prior to the stunt and he was unaware of this fatal error. His step-brother and a friend witnessed this unfolding tragedy as Overacker fell to his death to the water below the Falls.
Robert Overacker was married and had no children. Overacker became the fifteenth person since 1901 to challenge the Falls. He paid with his life. His body was recovered by staff at the Maid of the Mist.
Save the Homeless. Wasn't going to happen on a TS!
Robert Overacker, a 39-year-old man from Camarillo, California, went over the Canadian Horseshoe Falls at approximately 12:35 p.m. October 1st on a single jet ski.
Entering the Niagara River near the Canadian Niagara Power Plant, he started skiing toward the Falls. At the brink, he attempted to discharge a rocket propelled parachute that was on his back. It failed to discharge. His brother and a friend witnessed the stunt.
At first it seemed that he had survived the plunge, but the rapids have a strange way of flailing a corpses' arms around, often giving the appearance of a person swimming. Robert Overacker was later retrieved from the water, taken to Niagara General Hospital where he was pronounced dead.
His body was recovered by Maid of the Mist staff. Overacker, married with no children, became the fifteenth person since 1901 to intentionally go over the Falls in or on a device.

Ship Island Used as Navy Lab
The first of several planned Navy experiments integrating assorted platforms, sensors and models was held in the nearshore waters surrounding Ship Island, located near NRL-SSC, one of NRL's field sites, located on the Mississippi Gulf Coast.
With NRL as the lead agency, participants sharing a common interest of developing new techniques for environmental forecasting came together to form the Tactical Environmental Workshop - Littoral (TEW-L). Participants included NRL, the Naval Oceanographic Office (NAVOCEANO), the Fleet Survey Team (FST), and the Naval Oceanography Special Warfare Intelligence Surveillance and Reconnaissance Detachment Stennis (NOSWISRD Stennis).
This exercise required close collaboration and cooperation with the National Park Service enabling the experiment to be conducted in the Gulf Islands National Seashore, Mississippi District.
According to lead researcher, Dr. Todd Holland, the objective of the Ship Island exercise was to deploy, exercise, and critique the integration of various platforms, sensors and operational teams used to characterize oceanographic conditions in a near-to-shore setting, and to experiment with various approaches for rapid and effective characterization of the nearshore battlespace.
Platforms used included small unmanned aerial systems (SUAS), jet skis, and boats deploying cameras, echo sounders, wave buoys and current profilers while using uniquely skilled operators for data processing techniques, including on-site teams.
"Ship Island challenged the team with a dynamic, environmentally diverse setting, unimpeded by human activity, and served as a real-time laboratory uniquely suited for developing tactically-relevant capabilities," commented CMDR Monty Spearman, Military Deputy.
During the exercise, the FST collected bathymetry for "ground-truthing" other sensors and for use with area-specific, very shallow water (VSW) / surf zone (SZ) oceanographic models constructed for the experiment. They completed more than 80km of survey lines with a multibeam echo sounder and 23km of lines via jet ski sensing with singlebeam echo sounder.
NOSWISRD Stennis working with an assigned NOSW aircrew piloting the Raven B SUAS mapped over 26km of coastline and the corresponding nearshore waters surrounding Ship Island. While achieving this, they likewise developed tactical video collection techniques and procedures with the UAS pilots to support an ongoing NRL project entitled 'Estimating Surf Zone Bathymetry Using SUAS'.
In-situ sensors also played a significant role in the experiment. A newly engineered wave buoy deployed by NOSWISRD collected over two days of continuous wave data that was used to assist in validating products from the aforementioned Delft3D VSW / SZ ocean model. An acoustic Doppler current profiler (ADCP) deployed by FST provided current data across a 21-day stretch spanning the experiment. Hindcasts were made for the entire time period sampled by the ADCP. These were then compared to Delft3D nearshore current model predictions initialized from the high-resolution bathymetry collected during experiment and using the observed area tides and waves to induce flow.
The TEW-L workshop objectives are to continue to integrate emerging technologies, adapt tested capabilities, continue localized experimentation, develop improved strategies, evaluate and transition data to operational use, and develop and demonstrate nearshore forecasting abilities.

The Fred Tunstall Story
THE FRED TUNSTALL STORY
JETSKI FOR LIFE –
story by Shawn Alladio with support from Brenda Burns Chambers
On August 15, 1971 Clayton Jacobsen II, (his son is CJ3), signed a licensing agreement with Kawasaki Motors Corporation on the same day one expired with Canadian corporation, Bombardier. Clayton had several prototypes of PWC style water craft already off the drafting table.
When Clayton was a banker in the 1960’s he embarked on his idea from riding dirt bikes, which also were quite ungainly in the formative years. He built his first prototype in 1965 and began discussions with Bombardier, the manufacturers of the Ski Doo snowmobile line. The original ‘Sea Doo’ was born with a licensing agreement for a sit down version.
The Sea Doo watercraft line failed due to a lack of public support for the product line and it was plagued with mechanical issues. Ironically Sea Doo would be taking up the product line again in the two decades later and resurrecting the concept with a sit down craft.
Clayton continued to design and redesign and patent his ideas. For 20 years various people from around the world had been coming up with their own unique sit down hybrid person water craft’s from outboard, electric or propeller driven platforms. Clayton seemed to be the most persistent garnishing the OEM brass ring.
Clayton was known to possess a determined and difficult approach to his design concepts, he had a failure behind him with the Sea Doo and this project wasn’t going to get shelved if he could prevent it. He wasn’t the easiest person to work alongside with, but his energy and initiative is what brought to fruition concept. From conceptual phase and prototypes the Kawasaki team would take the product to the next level, to the consumer.
Clayton along with those at Kawasaki assigned to the development of this new project back in 1972 created additional six or seven designs of these craft in this critical formative stage. They referred to them as Water Jets or Power Skis during testing. There were actually other products with these names before them, but connecting all those product names would eventually land the ‘Jetski’ coin term and boating was changed forever.
Fred Tunstall was the Kawasaki man on the ground to get these products launched. This is his story.
‘In the early 1970’S I was conducting endurance testing in a lagoon in Carlsbad, Ca. I had hired 2 guys Gordon Garant and Bob McCord to assist in the riding and mechanical work’.
Gordon Garant is officially the first actual test rider for the product line. Similar to sending a man in space, Gordon was the first rider that every one of us have followed in his wake. Norm Bigelow would join the crew as another test rider. Few of you know Gordon’s name, and fewer know the origins of this community of Jetskiers. JS is synonymous with Jetski.
The JS hulls have changed over the years, the first hand laid fiberglass construction was done in Japan; from their humble beginnings, a dedicated crew focused on how to bring these JS craft to life.
Mr. Tunstall explains; ‘Our job was to put as many hours on the units that were being developed from scratch. There were many items to be tested and improved on as this was a completely new product and it was necessary to improve on each generation of items tested.’
These craft would eventually become to separate models, in the year 1973; WSAA and WSAB modeled from fiberglass hulls. The 398cc engines powered the first 400 JS units which came from a Kawasaki production snowmobile. The WSAA flat bottom hull configurations proved challenging as a rider.
The hull design would not undergo a change again until 1994 when a V-hull centerline was introduced. The WSAB hull was deeper on the centerline creating a more aggressive ride in comparison. But a lot was still left up to the riders capabilities. You had to earn your ride.
Two different hulls were decided upon for the initial launch, mainly because they weren’t quite sure at this phase how the product would be embraced and who their clients would be. The two hull variations produced different riding styles to match the hull characteristics underway.
There was still a lot of tuning to be done on the conceptual phase to production models.‘You can imagine how boring it was to ride around a lagoon that was about a mile long and quarter to half mile in size. If you can grab this thought, we were testing many versions of hull bottoms from stable units to some that were like riding on a round ball. Most of the riding was conducted kneeling in the tray down on the knees as we had not developed into the stand-up phase concept, mainly because of the gross stability of the hulls in the beginning’ states Fred.
‘You can imagine riding 6 hours on your knees and the pounding you received. At times it really got boring as we conducted longevity tests which had to be made for product durability and we kept accurate book keeping, all which was necessary to the program success. Engine drive and electrical components needed to be kept waterproof and metal pieces would corrode’, adds Fred.
The placement of the choke and start/stop switch was one of these initial electrical problems to solve, waterproofing was a focal point. Not much has changed as we still have the same concerns today with corrosion and electronics; however the advances in technology are radically different from the 1970’s.
These hybrid models weighed in at roughly 220 lbs. sharing the same power plant between both hulls. Parts were sand casted, hand molded and sanded, and the handle pole itself was also constructed from fiberglass. The original prototypes had a fixed aluminum pole, which was quickly phased into a pivot like handle pole that rose up and down, while the handlebars turned right and left. The exhaust at this time was above the waterline.
PRACTICE MAKES PERFECT (Continued below)

THE FRED TUNSTAL STORY CONTINUES:
This is a true statement even for research and product development, practice makes perfect, translation ‘trial and error’.
Fred explains, ‘to counteract the boredom we started creating some challenging encounters and finally made up an on-water course that we could ride on and also improve our riding and turning skills. Soon our knee riding began taking a toll on our bodies and from the pounding over waves and wakes and porpoising of the Jet Skis bow. Our riding skills improved and we started standing during some of the testing. This gave us some better riding experiences and we coincided with changing some modifications on the hull bottom and the handle pole. As our skills progressed the handling and speed also increased and our legs and knees were not hurting so much at the end of the day’ explains Fred.
The designs were becoming more functional for operator capability.
‘The entry area of the lagoon had a 5 MPH zone, but most of the time it was just the test crew on site and we kinda made our own rules. We used the 5 MPH buoys for our cornering on our course, and needless to say they took quite a beating. I don't remember how many we bought and replaced during our days there. I guess these buoys and the milk jug markers caught on and then some challenges between the riders formed and we had our own little race group. During our test period we had many visitors that had seen the Jet Skis from the freeway and show a curiosity about the terrors on water’ says Fred.
If you were driving on the 5 Freeway heading towards San Diego you could see these incredible boats in action. It was a curious thing to see, since there weren’t any of these Jetskis operating in any other place. Their initial curiosity would soon grow into a fast growing community fueled by surfers and dirt bike owners in Southern California.
THE JETSKI REV-OLUTION BEGINS
‘We let some of the locals attempt a ride. A few knee rode but none were able to stand up.’ Fred defines the initial introduction for a first time rider; it was a mixture of challenge and frustration. Not something most people would want to step away from until they mastered it, it was something akin to gambling, and you just knew at some point you would hit pay dirt. It was hard to walk away from it, like an addict, you wanted more.
‘My boss, Sid Saito, saw my expense report about buying buoys and became interested in our game we played. He allowed us to let more people ride. Steve Stricklin was one of the first to become efficient standing up (after the test group of course). Soon we were able to release some units to the general public as an evaluation unit. We would monitor their feedback and make more improvements’ adds Fred.
This was quickly becoming a buzz in Southern California. The Socal environment in the 1970’s was riding the wave of the surfing bonanza, the beach lifestyle, sunny days, Endless Summer and the dirt bike craze that was taking over the desert areas. The Barstow to Vegas off road dirt bike race was gaining a lot of attention.
Soon the Jetski craze was going to infuse those two communities with a version of a dirt bike on water.
‘Kawasaki finally approved the manufacturing of the Jet Ski and started a sales program. We had an introduction and demonstration day at a lake near Dallas, Texas. The team was under the guidance of Don Graves, a prior district manager, Steve Stricklin, Virgil Davenport, a Dallas service manager and I were present. Press day was on Friday, prior to Memorial Day weekend 1975. We had a real good promo and got lots of air time’ says Fred.
Tucson Daily Citizen, December 18, 1975, Page 34 Photo Caption Reads: "It's a Jet Ski a new water sport machine. The Kawasaki Jet Ski is demonstrated near San Francisco by Fred Tunstall. Propelled by a jet of pulsating water, the Jet Ski can change direction almost instantly or cut a full circle in just a few feet. It has the special feature that if the operator should fall into the water the Jet Ski will automatically circle back and pick up the rider.
‘During the summer of 1975 Steve and I recruited and trained 2 girls from Kawasaki's office staff to do demonstrations with us in and around Texas, Oklahoma and Louisiana. Every weekend we would travel to different lakes and give demonstrations and demo rides. We sure did get into great physical shape and got a good tan while we were at it’, states Fred.
‘After returning to Santa Ana, California and evaluating the progress of our effort we began a sales program push that opened dealerships around the country. Of course, California was the hot area and dealers started opening up all over. Riders were getting more proficient and of course some competition was forming at this stage. Seeing the enthusiasm and aggressive riding that was forming, well, it was naturally time to start an organized racing program’, says Fred.
‘Kawasaki enlisted the aid of local riders and dealers to form a competition committee that would be the ground work for a racing organization. Ed Losinski, Steve Stricklin's father in law, Jim Lathrop, Ron Lathrop’s father, and Ed Miller, a local Jet Ski dealer were asked to help form a competition group and set the technical guidelines for engine and hull modifications. As this was a new sport, many modifications to the original plan were forthcoming. All of which were trial and error. Everyone had their own ideas and changes were made like every week as we started having more and more riders joining the group that was to become the "UNITED STATES JET SKI BOATING ASSOCIATION", USJSBA. (Later the association became the IJSBA)’ explains Fred.

OFF AND RUNNING
‘Our first race was at our old testing area in Carlsbad, Ca. I estimate that about 50 boats showed up. Many different modified hulls, engines, and paint jobs. Good lord, what a rat race! Calm was nowhere in sight but all in all we had a race, no one was hurt and there were no fights over the new rules and modifications that amounted to success, so I guess we were off and running with a new racing sport’ Exclaims Fred.
Trio skiing to Hawaii doing OK SAN DIEGO - A team of adventurers attempting to cross the Pacific Ocean from California to Honolulu using Jet Skis is reported doing well in the fourth day at sea backers of the expedition said Thursday in San Diego. They last spoke with Tom Calamia and the support vessel Mercy Wiggins on Wednesday. The 32 year-old expedition leader and his relief crew were keeping one of their three motorized water scooters in the sea at times and were taking turns riding it. Their position was not determined but Calamia said prior to departing that the team expected to make about 250 miles each day except for some minor mechanical problems a spokeswoman said the mechanized skis powered by a high-pressure stream of water squirted from a jet pump were functioning as planned. Calamia and his relief riders David 33 and Tracy a college coed are trying to become the first team ever to achieve a long ocean voyage on the tiny machine. Calamia says one man has already gone 800 miles using a Jet Ski and another is planning a crossing from Boston to Ireland. The trio with the motorized yacht the Mercy Wiggins and a crew along for support and shelter in case of foul weather squirted out of San Diego Harbor. Their projected arrival in Honolulu was the day after Christmas - Press Telegram December 16, 1977
‘As you can imagine, many new modifications, riding rules, course design and as riding skills progressed so did ideas of race course design and a degree of difficulty was implemented. We used rider input and skill levels as guide lines to change and improve the program. Of course, not everything worked out as planned. Northern California had a good racing group and Bert Stanley, an attorney, helped form the group and also helped the IJSBA with technical and legal matters. Nor-Cal also had some good riders. Larry Rippenkroger, Brian Bendix, The Burns family, the Peterson family and others that helped the racing program get up and running’, says Fred.
‘Soon East Coast riders, Midwest riders and Southern riders got into the program and a steady growth of new ideas were set into the rule book. The racing was getting very popular and Kawasaki set out to hold races around the country. It was my job to make sure it happened. Steve Stricklin was hired and between us we put on a weekend race around the U.S. every weekend. What a nightmare, and it almost ended up in a divorce for me. Between Steve and myself I don't remember a summer weekend that I got to spend with my family the first couple of years’, remarks Fred.
‘The program grew so fast and before long we were getting riders from all over the world. We then changed the USJSBA into the "International Jet Ski Boating Association" (IJSBA) the very first foreign riders were from England and France. The program grew and we hired Dave as the new head of the organization. I had other duties with KMC (Kawasaki). I was installing dealers around the world, shipping product, parts, accessories, promotional material and other items to help promote the sales and racing end. What a rat race! On top of all that I was going to a lot of the races around the country’ says Fred.
‘As we grew bigger we needed a way to name a Number 1 rider and decided to hold an invitational race in Hawaii. The program was put together and also included television coverage. ABC's Wild World of Sports "spanning the globe to bring you the variety of sports", hosted by Jim McKay brought a crew to video the race and a celebrity was invited - Bruce Jenner, the Olympic Decathlon winner was there and rode the course. A great time was had by all’, explains Fred.
The Jetski beginning bears a pedigree of legendary purists who put the Kawasaki Jet Ski to the test, to the public and on the race track.
The rise of the IJSBA racing explosion complimented the recreational sales as well as the decline.
The American Watercraft Association was born out of this union. the Associate publications; JetSkier magazine, Jetsports Magazine and Ride Magazine are all generational evolutions from the humble beginnings of the ‘knee racing’ riders of the 1970’s.
The JS product development, technological advances, two stroke engine and four stroke technology, ergonomics and the changing faces of the industry hold a four decade block of maritime history.
We are all a part of that history, and these are the men who handed it off to you. Take care of the sport, yourself and others while enjoying your time underway, it is your responsibility to pass the torch and leave something good in your wake.

By Wendy Hinman
A history of Agua Hedionda Lagoon's innovative heyday
<!-- InstanceEndEditable --></TD></TR><TR borderColor=#ffffff><TD borderColor=#ffffff></TD><TD vAlign=top colSpan=2><!-- InstanceBeginEditable name="body" -->http://www.clickoncarlsbad.com/images/Stories/jetski/family051.jpgThe sun rises over Evans Point and scatters silver across the quiet waters of Agua Hedionda’s back bay. A muffled boat floats out onto the glassy stillness and with a thumbs up from a skier on the dock, it hits the gas, breaks the calm and another perfect summer day begins on Carlsbad’s busiest lagoon. The memories of such days are as steady as the water lapping the shore as the sun sinks low and hulls are rinsed off at end of day.
This summer it is wave runners and wakeboarders out for fun, but in the ’60s it was water skiers on wooden skis and the ’70s and ’80s added Jet skiers. According to a kid who grew up on the lagoon, there was a time between Fox’s Snug Harbor and Whitey’s Landing (near Bristol Cove) when each were putting about 100 boats a day in the water.
From the air it looked like a Where’s Waldo drawing. So in the early ’60s, Harry Walton and Ed Urbanski, a couple of Carlsbad’s finest under Police Chief Max Polkowski, were sent out on lagoon patrol. “Our first boat was a 36-foot landing craft we got from Army surplus for $500,” Walton said. We used it for a year and sold it to the City of San Diego. They put it in Miramar lake (reservoir) and it sank. Our second boat was a 24-foot Captain’s gig, also from Army surplus.” The water police objective? “To keep everyone going counter-clockwise.”
http://www.clickoncarlsbad.com/images/Stories/jetski/ski_hut.jpgOnly one or two citations would be written on any given weekend, but Walton said, “It was terrible. I’d go through a full first-aid kit every Saturday and Sunday and we’d send three or four people to the emergency room.” Here is where Walton said his 15 minutes of fame came. Walton thought a flag—similar to the ones divers used—might work instead of the skier raising his hand. The observer in the boat would raise the red flag to signal a down skier.
Did it work? Soon the higher-ups were concerned. Walton said, “The Division of Small Craft Harbors came down to see why we weren’t sending accident reports anymore.” Always on the cutting edge, Carlsbad passed a city ordinance requiring use of the flag in 1960. The State of California caught up later and now the flag is standard practice for skiers and wakeboarders.
http://www.clickoncarlsbad.com/images/Stories/jetski/Jet%20Ski%20Old%201.jpgAnother Carlsbad innovation was a small, flat, bottom speedboat designed by the Litchfield brothers. Outboards would be ousted from the lagoon and drag races would ensue. Walton said they could reach 100 mph sometimes. It is hard to imagine that without anyone hitting the mud flats, but low on the water, they were a thing of powerful beauty.
For all the action in the water Rusty Sharman said, “John Fox ran the landing like a ship. He’d wear Navy dress whites and ring bells every hour. He was quite a character.” Walton said of Fox, “He was an ex-Navy chief” and the American flag went up in the morning and down in the evening punctually and ceremoniously.
Before Carlsbad High School offered surfing or beach volleyball for P.E., it offered water skiing as a summer school class. Many students began the summer with a wobbly, double ski start and ended with a single ski dock start. The teacher and boat driver was the newly elected city councilman, Bud Lewis.
http://www.clickoncarlsbad.com/images/Stories/jetski/new_photo.jpgThe biggest problem with water skiing has always been the need for driver and skier to read each other’s minds. It’s hard to holler over an Evinrude. What if the skier could drive himself? Or, as Clayton Jacobsen II conceptualized, what if you could motorcycle on water? Jacobsen made a prototype Jet Ski of aluminum by 1965. Instead of an outboard he went inboard with an internal pump-jet and later made the hull out of fiberglass. By the early ’70s Jacobsen had sold the patent to Kawasaki with Jet Ski becoming its official name. Kawasaki needed to do some R & D and needed a water-filled laboratory.
Meanwhile, back at the lagoon, Rusty Sharman grew up a stone’s throw from the water, “next to the Fox’s house.” His dad had a bait shop at the landing. Dave and Rolf Sammons came with their dad who raced speedboats. (Fox eventually sold the landing and then Fred and Lee Lathrop took up the lease from its LA owner). They had fished the lagoon, driven boats, skied, kneeboarded and tinkered with engines at water’s edge. Cindy Lathrop said, “It was a family place. I remember gathering around the fire ring after skiing all day. January 1 was a big day with polar bear patches. Weekends would be packed with trailers all the way up the hill. Geez, I think I skied before I could run. I remember my dad running along the beach pulling me.”
http://www.clickoncarlsbad.com/images/Stories/jetski/Jet%20Ski%20Old2005.jpgWhen Kawasaki arrived with its prototypes, they found willing test pilots in these 12- and 13-year-olds. They would ride for gas and Kawasaki would pepper them with questions that Sharman said were “mostly about improvements and safety issues. They ran a pretty extensive test program. I remember one guy whose sole job was to test the stretch on rubber belts,” after a few hours in the water.
A few years into it, Kawasaki’s white-coats rented a ballroom in an Oceanside hotel and invited “about 10 families who frequented the lagoon to come and answer questions.” Sharman remembers that there were families so often at the lagoon they became a sort of extended family. “There were the Lathrops, of course, and the Whiteings, the Cockrans—Randy Cockran was the first paid test-rider—the Egdahls, the Westes, the Leiths, the Turners.” And Cindy Lathrop was not a bad Jet skier for a girl!
Kawasaki came out with its first model in 1973 to limited production. It was a stand-up with a 400cc, two-stroke engine. They came out with a mass production, JS400-A, in 1976. Not only did these kids help Kawasaki successfully develop this new recreational vehicle, but the Jet Ski helped develop some of their futures.
http://www.clickoncarlsbad.com/images/Stories/jetski/engines.jpgSomething in a man wants to take anything that is plain fun and make a competition out of it. As the Jet Ski became commercially successful, Jet Ski races began to spring up in our lagoon and beyond. The Sammons, Sharman, Brian Bendix and those who didn’t realize they’d been practicing were set to take the field.
http://www.clickoncarlsbad.com/images/Stories/jetski/jetski%20c%20list%20007.jpg“It was like a moto-cross track in the water,” Sharman said. He made the All Southern California team sponsored by Snug Harbor Ski Hut. Dave Sammons said there were different races: “Stock and modified skis, and in the early days there were weight classes.” Both big boys and standouts for the CHS wrestling team, they both added Jet Ski accolades next to their wrestling trophies. “The first Jet Ski race was at Mission Bay in 1977. The first race in Carlsbad was at the harbor in ‘78,” he said.
But Jet Ski racing, like NASCAR, is a team effort. When the weight classes were dropped they became mechanics on the crew. Along with Brian Bendix and his brother Rolf, Sammons said, “Those were some good days. We traveled all over the country.” In the early ’80s Transworld Recreation had taken over the landing and Sammons was on their team until he started his own company. Dave’s passion was in how the engines worked. He designed the first fuel injector for the Jet Ski.
Jacobsen designed both a stand-up and sit-down version of the Jet Ski initially. He had originally tried to sell his idea to Bombardier (a snowmobile maker, Ski Doo to Sea Doo) as a sit-down. When that didn’t pan out, he went to Kawasaki with the stand-up. The stand-up design is more difficult to master, but when it became commercially successful, Kawasaki, Yamaha and others began marketing various designed personal watercraft (PWC). They also upped the power. Kawasaki’s latest is the Jet Ski Ultra 250x, with a 250 horsepower, four-stroke, supercharged engine.
http://www.clickoncarlsbad.com/images/Stories/jetski/Jet%20Ski%20Old4008b.jpgJet Ski racing reached its zenith by the late ’80s. Sharman said, “For some reason, as the sit-downs became more successful, racing declined.” There are still Jet Ski races, but nothing on the scale of those early days. Sharman remembers the Olympic Long Beach Marine Stadium packed with spectators. Or one world final in Lake Havasu. “There were 1000 Jet Skis all started at once and the smoke was almost unbearable.” That smoke has also stalled the sport. Many areas only allow clean running, late model PWC. Stand-ups can still be ridden in California, but can no longer be sold in California.
http://www.clickoncarlsbad.com/images/Stories/jetski/Lagoon.jpg While most guys were racing Jet Skis, Randy Laine was sneaking one under the freeway, the train trestle, 101 and out into the open ocean. Laine was a surfer and he had to get the thing out into the waves. He rode, crashed and jumped the waves at Tamarack. He was an innovator of tow-in surfing and freestyle Jet Skiing. Like freestyle snow skiing, this is not a first-guy-over-the-line event; it is a judged event. The winner catches more air and demonstrates more insanity—with technique—than the second place finisher. Laine’s nickname in this world is “Father of Freeriding.” (Check out clickoncarlsbad.com’s editorial features for Laine’s entire story).
Laine is still sponsored in this extreme sport. Sammons still builds engines for folks in his garage. Sharman works for North County Jet Ski. It has been rumored that Tony Finn, a pioneer of wakeboarding in the ’90s was sighted a time or two on his “Skurfer” at Snug Harbor. But the halcyon days for the lagoon were those three decades of the ’60s to the ’80s. Some have said insurance and permit laws cut into the fun. Some say rules and strictures have squeezed the PWC industry. Whatever the reason, an era seems to have past. “Those were magical days,” Sharman mused. “There are a lot of great memories down there,” Sammons said. “It was a unique place for awhile,” Walton sighed, then added, “When the sun went down and the water glassed off, it was the most wonderful water skiing in the world.”
Engines and equipment have surely changed, but Agua Hedionda has not. Jet Skis can still be rented. Wakeboarding can be learned. Innovations are waiting. The sunrise still spills silver across the surface and the wind dies every evening leaving the stillness lingering with possibilities. •

SOLO Personal Ski Machine
The SOLO Personal Ski Machine is electronically controlled by thumb-operated buttons on the tow handle enabling one person to become the skier, driver and the spotter.
According to the manufacturer, SOLO is powerful enough for some serious skiing and the 95 hp engine is quieter than most conventional 2 strokes. Developed by water skiers and with a top-end speed of 65kmh, SOLO is capable of deep-water slalom starts and operates in fresh and salt water.
A kill switch is built into the handle so that the engine shuts down and brings the boat to a quick stop when you fall off. An automatic "downed-skier" flag also pops up when the skier falls and retracts when the engine is re-started.
The SOLO is also relatively easy to transport at approximately 170kgs and 2.4m in length.
The SOLO costs US$7495. SOLO Watersports is currently in the process of establishing an Australian distributor. See www.solowatersports.com (http://www.solowatersports.com/) for full specs and video images.

Jetski long distance ride on Stand Up Kawasakis from San Diego to Hawaii
<!-- google_ad_section_end -->
<!-- google_ad_section_start -->CIRCA 1977. Where were you?
So you think you have a distance record?
These were real machines in open ocean storm conditions.
Any records today pall in comparison.
Try doing your long distance ride on a stand up.
Sit down watercraft cannot compare to what these three riders endured in 1977.
Indiana Gazette, May 23, 1980 Page 45
The jet ski craze hasn't slowed down a bit.
Themaker of the waterborne cycle in fact is gearing up for more sales than ever. There are now close to a thousand jet skis sold and we are looking for more unit to be sold this year said Fred Tunstall a jet ski factory rider for Kawasaki in Santa Ana California. It's growing and a wild market. Guys like Tom Calamia, he headed up a team that went all the way from San Diego California to Honolulu Hawaii on jet skis with the aid of a a stabilizer wing that Calamia developed.
Now he is trying to mount an assault on the Colorado River. I want to go 320 miles up river said the 33 year old motorized skier. This is the wrong way up the river but I think I can do this and it’s the only thing that hasn't been done by jetskiers.Tunstall says skiers are doing such things as soaring off ski jumps skimming across the water while drivers stand on their heads and riding along with other people on their shoulders.
Jet ski competition with riders racing around buoys or running slalom courses. They're doing that's that I'd never considered . Tunstall said.Still no one seems to be close to Calamia, it took daring. One Christmas, David Calderon and Tracy Shelley zigzagged all the way to Honolulu on jetskis. We were told that December would be a good time to make the run Calamia said.
But we ended up running into the worst series of storms in 10 years. There were five big storms and we lost no one. One or the other of the skiing team stayed on a ski all the time when weather permitted for the trek he said. The trio received a hero's welcome when he skied up on the Hilton Hawaiian Village Beach in Honolulu.If I was going to do some things different Calamia said he would like it where you could run the ski right up onto the mother ships deck. We had to hoist the ski on and off the ship and it was pretty rough when we had to come back aboard the boat when the weather got bad.
His planned another trip up the Colorado River which should take only about five days and be just as spectacular as the Hawaii run. I've picked the one area between Lake Mead and Marble Canyon City where it’s all most all whitewater said Calamia. He will be making the trip as the only skier and he said he's hoping he can get some sponsorship for the rapid run. Calamia says the main reason he's going is to promote his stabilizing wings that attach to a regular jet ski and allows it to over waves or rapids that wouldn't be possible otherwise.
Was his product what was to become the Fun Tech Wedge? – K38
Water-Cyclists Running Late on Ocean Voyage to Hawaii
San Diego-Three Californians attempting a 2,500 mile voyage to Hawaii on water-borne motorcycles are two to three days behind schedule because of heavy seas and foul weather a backer said Monday. William Barrett Jr. of San Diego, who is helping to fund the adventure said Tom Calamia, David Calderon, and Tracy Shelley have been fighting 30-foot waves generated by two storms since their departure last week for Honolulu."They finally had to ease up and move out of the storm's way and lost about 300 miles." Mr. Barrett said. 'They are making about seven knots and are south of their course by about 100 miles." Mr. Barrett said the trio, are hoping to make the longest journey ever on Jet Skis- these are modified by a stabilizer device invented by Mr. Calamia, now expect to arrive in Hawaii by Thursday if all goes well. The Mercy Wiggins, a 62-foot motor yacht, is along to provide fuel, food and storm shelter for the expedition.

Tom is skiing to Hawaii
Somewhere in the Pacific Ocean Tom Calamia is riding the waves. Skiing from California to Hawaii. Calamia and two relief riders set out on Monday on their 2,000-mile adventure using Jet Skis, a mechanized version of water skis powered by a stream of water squirted from a jet pump. The Mercy Wiggins, a 62-foot motor yacht skippered by Richard King, will provide fuel and support along the zig-zagging route which Calamia estimates will take them an additional 1,000 miles distance. The yacht's nine-member crew will allow relief drivers David Calderon, 33, and Tracey Shelley, a 21-year old Grossmont College coed to rest. And it could provide a safe haven should a storm blow up.

Heavy Seas Delay Jetskiers
Daytona Beach Morning Journal, Dec 27, 1977
A trio of California jetskiers are behind schedule because of heavy seas and foul weather. Barrett said the trio, hoping to make the longest journey ever on Jet-Skis these modified by a stabilizing device invented by Calamia-now expects to arrive in Hawaii by Thursday if all goes well. "They called in on Christmas and wished everybody a Merry Christmas from the middle of the ocean', Barrett Said.
One of the three adventurers, to be determined by a coin toss with the loser getting the nod, plans to stay on one Jet Ski as long as possible to set an endurance record, said Barrett. Each rider has been taking turns keeping one of the mechanized water-borne motorcycles in the sea at all times. Barrett said seas have been so rough at times that 'the guy who was on the ski actually was higher than the pilot house' of the Mercy Wiggins, the 62 foot motor yacht which is along to provide fuel, food and storm shelter.

End of a long ride
Three travelers who hit the beach 16 days after their way across the Pacific Ocean have ended their journey . They began in San Diego are shown arriving at HONOLULU AP Sixteen days after they left San Diego three young jetskiers glided ashore at Waikiki Beach after crossing more than 2,500 miles of the Pacific Ocean on a water ski The trio were cold and exhausted but jubilant to have finished their odyssey. Friday afternoon and said their test of leader Tom Calamia 32, was the designer of a stabilizer on the jet ski was a definite help but grueling a grueling trip. He hopes to sell the stabilizer to the military and to Kawasaki.
Dave Calderon 33 was one of the three of the jet skiers which propelled them a woman Tracy Shelley across the Pacific. A fishing trawler carrying nine persons accompanied the three skiers during the week journey. The trio took turns zooming across the water on a single jet ski; a combination water motorcycle powered by a stream of water forced through a jet pump.
They said two spare jet skis were never used except for the last few miles when all three wanted to glide in to shore. The three said they encountered ocean swells of up to 25 feet and 40 knot winds throughout much of their journey Calamia said. It was only the last three days that the water was relatively calm and smooth said Calderon. Calamia said one of the more frightening moments of the voyage occurred when he rammed into a turtle and was knocked into the water Hot baths lots of beer and soft beds topped their agenda of touring before they fly back to San Diego

Jet Skiing Becomes Wild Wooly Sport
RBI By VERN GRIFFIN News Service
The jet ski craze hasn’t slowed down a bit The jetski won't support a rider unless it is moving through the water. To increase the ease of riding and reduce the time a rider spends in the water. Fun Tech has invented a wedge to slip around the hull of hte ski so it will support a man weighing more than 260 pounds. The wedge also adds maneuverability and it can be removed quickly to return the ski to its racing form.
Yacht Yields Huge Pot Cache
May 4, 1971
San Francisco customs agents on Coast Guard boats ran down a yacht in a sea chase 10 miles outside the Golden Gate Monday and seized five tons of marijuana worth 1.5 million the largest haul in US history, the government revealed yesterday. Eight persons were arrested late Monday on the yacht Mercy Wiggins. The Mercy Wiggins had been under surveillance from the time they entered US waters after a trip to Mexico, working on the case for a year.
The Mercy Wiggins had been making regular trips between San Fransisco and San Diego. Arrested were Virginia Marie Pope 52, John Ferris Pope 53, both of Kealakekua Hawaii; James Olson 36 of Hawaii; Captain Cook, Gordon Maack 38 of Kailua, Kona, Hawaii; Richard Michael King 42 and James Russell Vukich 25 both of San Diego, Robert Craig Light 30 of South Seattle Washington and Miki D. Thieda 25 of La Jolla, CA.

REDISTRIBUTING THE JET THRUST WEALTH FOR FUN!
Okay, so these are fun for what? Hours or days or years depending upon your idea of fun. For sure! And great fun. I want more freedom at speed. I'd rent one but not buy one personally. They all offer a variation off of the original design, price points, safety concerns and legal boating issues apply.
These hybrid units adapt the water thrust and redistribute the force of water from the jet stream to 'lift' up a 'pilot', which now combines boating with flight. So would a pilot then also need to be certified for flying as well as boat operations?
Safety concerns again arise in height and hazards with fixed or flying objects as well as water impact and recovery. This is going to require a secondary support vessel.
Cool new products however. Will be interesting to see where we are 20 years form 2013.
The JetLev was the first of these products to be launched. I was working as the Water Safety Director for the 2010 IJSBA World Finals and the JetLev folks had a display in vendor alley and were doing demos on Friday and Saturday during race breaks. They were also having demos near the slalom course during the week's racing. There was a lot of buzz about them there. This is where the concept took off in the PWC community. In 2011 we soon saw the rush on this new concept from others.
WATER JET PACK
http://<IFRAME height=315 src="http://www.youtube.com/embed/im1iNq02Kz0" frameBorder=0 width=560 allowfullscreen></IFRAME> (http://<iframe width="560" height="315" src="http://www.youtube.com/embed/im1iNq02Kz0" frameborder="0" allowfullscreen></iframe>)
'The jet pack in the video runs off of water. It's the first of its kind. The tube you see attached to it, that goes into the water, goes into a gas powered small boat that follows whenever the jet pack pilot is flying (if you look close in the video you can see it).
The jet pack itself is super safe. It's actually approved for the water by the coast guard, and there is nothing illegal about it :) You need to be at least 18 years old to fly it. It takes about 30 minutes to an hour of training, and then you're set. These water jet packs are going on sale very soon, and you can contact the company to get on their waiting list. You can contact them here http://www.jetlev.com And you can find out a lot more about them on the website.
The jet pack is able to fly purely by the volume of water that comes out of the two hoses that are attached to it. It shoots out 10 times more water volume then a fire hydrant does. You can stick your hand right where the water comes out, and you won't get hurt at all, as you can see several times in the video.'
"When I was 14 years old, I watched James Bond fly a jetpack in the movie "Thunderball," and I have dreamed of flying one ever since. However, after decades of patiently waiting, jetpack technology didn't get any closer to mainstreaming personal flight … so, I decided to invent a machine that would." – Raymond Li, Inventor
SAFETY & PATENTS
Pilot safety is our top priority. With more than eight years of research and development, and over 10,000+ hours of flight-testing and refinement, the JETLEV R200 is a dependable, adventure-ready recreational flight vehicle. In 2010, the JETLEV R200 was awarded a Recognized Exemption by the United States Coast Guard, which means that the JETLEV R200 has been cleared to fly throughout US waters in accordance with local motorized watercraft restrictions. Similar authorizations have been granted by Marine Certification Authorities throughout the world. Moreover, a large community of insurance companies formally underwrite JETLEV activities throughout the world
Your flight begins as a 200-HorsePower marine engine pumps water up a 33-foot hose at over 1,000 gallons-per-minute, generating over 420 pounds of thrust. When the water reaches the ultra-light backpack, it's directed through two nozzles at up to 60 PSI. Aiming the nozzles creates smooth, stable turns. And the motorcycle-style throttle lets you climb, dive and hover up to 30 feet above the surface. The 5-point safety harness and trapeze keep you in optimal flying position, while the fuel-efficient motor gives you hours of flight on a single tank of high-octane gasoline.

One of the original concepts for a PWC Rescue Board out of Hawai'i
11-18-2012, 09:03 PM
April 30, 2007 Ever wondered what it feels like to power through the water like a dolphin? The SeaBob (http://www.seabob.com/) is like a cross between a jet-ski and a bodyboard -hold on tight and leap through the waves, or turn downward and head for the ocean floor with speed, grace and agility. This simple device creates a whole new category of recreational vehicle, and it looks like a blast!
Put on your goggles, hold onto the handles, tuck yourself in behind the hydrodynamic plastic body of the SeaBob, and gently thumb the accelerator sensor. The electric impeller jet motor pulls you forward gently at first, but ramp it up to full power and it belts you through the breakers at a speed of 15km/h. Hold on tight!
Take a deep breath and dip below the surface, powering downwards towads the ocean floor. Steer yourself by moving your bodyweight and using your legs like the tail of a fast fish, and experience the exhilaration of flying along the sand, dodging rocks, coral and startled fish as you go.
Let go of the handles and the SeaBob powers down and stops almost immediately so you don't have to swim far to get it back. There's really not that much more to it, it's a simple and intuitive device that lets the user experience underwater speed in a very physical and engaging way.
The SeaBob, designed in Stuttgart, Germany and available now, is powered by a patented electric motor, drawing on rechargeable Li-Ion accumulators and driving an impeller jet propulsion system. The standard model puts out 2.4 kW (3.3 HP) and the Jet and Cayago models use the larger 3.6kW (5 HP) engine, capable of 20kmh. A full charge takes 6-12 hours when plugged into a wall socket, and is good for around an hour belting around underwater. Extra battery packs are available, but they're fairly pricey, as is the rest of the range.
A nifty LCD cockpit display shows you the engine power, remaining operating time, charge state, water temperature and a depth gauge. The machine comes with a factory setting that shuts the engine off below a depth of 2.5 metres - a handy safety feature that can be adjusted by the adventurous to a maximum depth of 40 metres. Clearly if you're going to be zooming around at that sort of depth you need to think about scuba gear.
20kmh through the water is roughly 5.5 metres per second, so if you can hold your breath for one minute underwater, at top speed on the , you'll pop up for a breath around 330 metres down the beach. Do take care you don't pop up in the path of a jet-ski, because you won't be coming off the winner in that little contest.
Check out the demo video (http://www.seabob-jet.org/video/video_uk.html), if you can put up with the awful corporate techno of the SeaBob song in the background...
Apart from the recreational market (and we can see this being a real hit on hire at leisure resorts all around the world) the device clearly has James Bond written all over it too - will we see blue ocean-camoflage SeaBobs in use by Navy Seals and special ops agents in the near future?
The standard SeaBob RaveJet retails at EUR 7,675.50, with the higher-powered SeaBob Jet 5.12 going for EUR 9,371.25 and the deluxe Cayago VX2 (with extra accumulator box) for EUR 11,281.20. Not cheap, but an absolutely unique experience and a heck of a lot of fun!
Down waves, skimming across the surface or diving underneath the water - Delfjet is a remarkable surfing device designed to allow humans to emulate the motions of one of our most admired sea creatures - the dolphin. Capable of speeds up to 25 kmh and diving to 125 metres depth gives the Delfjet unprecedented versatility - not only can you get to waves more easily when bodysurfing, but when the ride is nearing its end you can simply motor off the front of the wave.
The diving depth can be set to a specific limit according to the user's needs, enhancing safety for amateur divers who can restrict depth to only a few metres.
Steering of the agile Delfjet is through transfer of body-weight and speed is controlled via simple to operate hand-throttles on either side of the body - a bit like a motorised "boogie board". When pressure is taken off the throttle sensor (ie. you fall off) the Delfjet stops like a jet ski does, so that recovery is easy.
The Delfjet also has solid environmental credentials - the electric drive mechanism was developed to produce the ideal amount of torque with great efficiency and the 5 horsepower jet engine is emission-free and almost totally silent.
The electronic jet engine is also service and maintenance free and power comes from rechargeable high-energy Li-Ion cells that provide enough energy to run the Delfjet for an hour at full speed.
Several models are available including the professional "Black Shadow" - built specifically for diving to greater depths - and a rescue model that can accommodate two people and still achieve speeds of 18kmh.
The models vary in price from US$16,000 to $23,000, so they're certainly not going to set any sales records - they'll be the toy you have on the back of your million dollar cruiser.
One model has been brought in for an Australian customer according to Bruce Batterham of Squadron Boat Sales who distributes the Delfjet.
Squadron Boat sales has offices in Perth, Adelaide, Sydney, Gold Coast, Sunshine Coast and Port Douglas. To learn more phone (02) 9736 2400, email email@example.com (firstname.lastname@example.org) or visit www.squadronboatsales.com (http://www.squadronboatsales.com/).

INFINYTE i4 Electric personal watercraft
For many people who own lakefront property, noisy combustion-engined motorboats that leave clouds of exhaust and oil slicks in their wakes have pretty much become a given. Hopefully, however, quiet and clean-running electric watercraft may soon take over a significant portion of the pleasure-boating market. While consumers can already pre-order the planned 8-passenger solar-electric

KYMERA JET POWERED BODY BOARD
Longing for a cheap and easily transportable personal watercraft Jason Woods took matters into his own hands. He set about designing a jet-powered body board, light enough to carry under your arm, small enough to fit in the trunk of a compact sedan, and efficient enough to enjoy all day without breaking the bank. Although the first three prototypes ended up at the bottom of a lake, the young garage designer persisted. Three years on his dream has become a reality – introducing the Kymera jetboard.
The idea came about in 2004 when the water-sports-loving Woods found the upkeep and transport of his 1960's era ski boat impractical. He was frustrated with having to own a gas guzzling truck to move his ski boat around, and then once on the water his leisure time was running at 5 miles per gallon.
“After selling my boat and truck I purchased a sensible sport compact to save some money,” Woods said. “Missing the water I drove to the lake one summer day and sat by the shore and realized there were ten times more people on shore milling about than there were out having fun on the water.”
He realized that there were two groups at his local lake; those who can afford the big boat and big car to tow the hefty things around, and those who can't so just stand on the bank and watch. Bridging this gap became his inspiration.
“I really wanted to create a personal watercraft that had all the fun and none of the hassle of jet skis or boats,” Woods told Gizmag. “My specific goals were that it would have to easily fit in or on a compact car, it would have to be safe, it must be easily hand carried and launched anywhere and it had to be able to run all day. My inspiration though, really came from watching people at the lake awkwardly wading at the waters edge while the privileged few were out on the water.”
The next day he embarked on a journey that would last three years. In his garage he set about researching materials and propulsion systems. He worked through designs that allowed for speed without adding too much weight.
The first three prototypes sank. Undeterred he learned from his mistakes, along the way gaining skills in molding carbon fiber until the current hull design began to take shape. The two main issues he faced were displacement, that is refining the delicate balance between weight, size and flotation, and getting air in and keeping water out. Eventually he got it right and after developing an electronic ignition system, trialling a number of steering methods and overcoming issues with overheating, he was ready to take to the water.
“I have only taken it out in public a few times but consistently everyone wants to know 'what is it?!' and 'where can I get one?'" Woods said. "Occasionally people respond with 'Oh great, now I'm going to have to buy one for little Johnny'” he said. “Its really been the most rewarding part of the project seeing the overwhelming reactions from everyone who's seen it.”
The current model has a top speed of around 15 mph (24 km/h), depending on the weight of the user, and is driven by a 6 hp micro jetpump which puts out around 55-60 lbs of thrust. The total weight of the Kymera is around 10 lbs (4.5 kg), with the engine, jetpump, electric start, and intake / exhaust system accounting for 7.5 lbs (3.4 kg).
Woods says the Kymera can run continuously for over two hours on less than a quart of 92 octane+ plus fuel, which is its current fuel capacity. "I would argue its the most fun you can have for a $1 these days,” he told Gizmag.
The name Kymera was inspired by a species of deep water shark and the design and name are both patent pending. Jason Woods is a 27 year old sound, lighting and video engineer working in corporate event production with design one of his passions and hobbies since high school – one that he said he would like to pursue more closely now he has been given a taste through developing the Kymera.
If you'd like to give him some encouragement or maybe purchase a couple of thousand of the Kymera to help him realize his dream of quitting his day job to concentrate on developing the jetboard, he can be emailed here (email@example.com).
The Kymera isn't the first example of the powered-board platform we've seen – if you have a little more room for freight there's a already a stand-up option on the market in the form of the Powerski JetBoard (http://www.gizmag.com/go/3871/).
The short video gives a taste of the Kymera in operation:
<!-- INTEL BANNER -->http://<IFRAME height=315 src="http://www.youtube.com/embed/oDNu-mfdzjk" frameBorder=0 width=420 allowfullscreen></IFRAME> (http://<iframe width="420" height="315" src="http://www.youtube.com/embed/oDNu-mfdzjk" frameborder="0" allowfullscreen></iframe>)
First off a correction to the above is that the entire jetboard actually weighs about 28lbs the power plant (Engine, starter, jetpump etc) weighs less than 10lbs around (7.5lbs to be exact). And currently tops out at 15mph or so, however this is not because of a lack of power but rather a lack of capitol to design my own Jetpump from scratch to best use the power. With the right pump I would expect 20 ~ 25mph with no other modifications. But let me tell you 15 feels a whole lot faster when your face is 6in off the water.
There are also lots of other uses for my invention beyond recreation. Ive actually already designed and built a version for life guards that can be operated from the tower giving much needed visibility and speed. I also designed a radio fence option that would allow the throttle to cut back to 20% automatically if a child rider venture to far away from their supervisor.
Keep the questions coming! Ill also be responding to comments here on Gizmag, and again thank you all so much for all the support!!!

December 22, 2005 What’s better than an Ocean Scooter? Two or more Ocean Scooters – that’s what! This is one of the those products which just screams, “why didn’t someone think of that before?” An inflatable , battery-powered electric boat that’s fast enough to give the kids a thrill, and slow and soft enough to be used in a swimming pool for everything from polo through to your good old fashioned demolition derby. The ASTONE ‘Ocean Scooter (http://www.oceanscooter.net/)’ went on sale in Australia this month but global supplies will be available for the next Northern hemisphere summer. The Ocean Scooter comes with a battery-powered display, a variable speed throttle, automatic power shutdown, full waterproof circuit protection and a protected propeller body which is impenetrable to probing fingers. And at AUD$269, it’ll offer a very high bang-per-buck factor.

ELECTRIC INFLATABLE WATERCRAFT
August 21, 2007 Inflatable watercraft are now available for dozens of different recreational purposes, from basic loungers through to purpose-built inflatables that come in every imaginable size and shape. A new product from Icontech, the Electric Inflatable Watercraft, is a battery powered, sit-down jetski (http://www.gizmag.com/tag/jetski/)-like product, that has a maximum speed of 10kmh and is an affordable alternative for the beginner or novice water enthusiast.

February 21, 2008 With 200 bhp PWCs now commonplace, there seems to be a trend emerging of using the PWC as a dockable powerplant for a larger craft (http://www.gizmag.com/go/6995/), significantly extending the versatility and recreational options of the ski, the docking craft as a water platform, and the carrying capacity to five people and beyond. The Waveboat is to be launched next month and it offers some compelling functionality – just add your Yamaha Waverunner PWC and you have a high speed (video here (http://www.fun-f.com/fun-factory-video/video-jet-boat-yamaha-motor.php)) jetboat with ultrasweet handling and all the trimmings. With prices starting at US$8000(EUR5600), it’s a bargain accessory – sadly available for Yamaha Waverunners only
Assembling the Jet Ski and the Waveboat takes less than a minute out of the water and only a few seconds on the water, though the soul of the product is its sweet handling as can be seen from the accompanying video. “The product was conceived to offer a pleasure and an unforgettable riding experience due to its feather weight incisive hull, its solidity and its reliability, which preserve all the liveliness and handiness of a jet ski,” said Fun Factory’s Vladimir Nunez.
“The aim is to offer a diverse range of customisation options and accessories so that people can set up their own Wave Boat to suit themselves – tables and cushion layouts and headrest handles and … it’s essentially very customisable.”
The Fun Factory is already well versed in the rental and resort markets where its ingenious Yelo 260 (http://www.yelomarine.com/Hydrojet-yelo-marine-nautical-leisure/hydrojet-yelo-marine-nautical-leisure.htm) is a recreational watercraft with all the bases covered regarding safety – it’s almost entirely idiot-proof, 100 percent reliable and there’s no access to the propeller. It is hence suitable for rental. Designed around a Yamaha outboard motor, though you’d never know, the Yelo 260 will reach 15km/h quickly, is very stable with three comfortable seats and is fun to drive, as it is very responsive at low speed and driven by joystick and hence appeals enormously to the youth market.
For water sports centres and rental companies alike, the Yelo gives you peace of mind as there is no access to the propellers and the construction is safe and robust.
The company is seeking to expand its business in as many countries as possible, and would welcome (firstname.lastname@example.org) distributor inquiries.
We’ve previously written about PWC docking devices here and some recent news is that Dockitjet is developing its entirely different take on the same theme as WaveBoat– docking a PWC with a Dockitjet results in one of the fastest lightweight RIBs on the planet. They’ve now taken things a step further using carbon fibre panels and adding surfboard racks and rod holders (http://www.dockitjet.com/index.html). The versatility of the package is impressive as it leaves a platform for exhausted surfers to replenish, and enables the ski to be cut loose for transport, recreational heaven and maybe even towing surfers onto waves. The prototype is reportedly being used to great effect putting surfers right where they want to be with ease and comfort.

The Quadrofoil is a prime example of this phenomenon, having been created by three young Slovenian designers inside six months, and launched at Slovenia's Internautica (http://www.internautica.net/) exhibition last week.
So successful has been the response from the public that a short production run of 100 units will be completed before the year is out, giving the Quadrofoil a concept to market time of less than 12 months, and with some ambitious plans for faster future models and perhaps even a race version. The company is now in capital raising mode to fund production plans for more than 10,000 units a year from 2013 onwards.
The retail price of the Quadrofoil will be EUR15,000 (US$19,100) and a spot on the waiting list can be secured with a EUR5000 (US$6,370) deposit.
What you get is a two-person electric hydrofoil (http://www.gizmag.com/tag/hydrofoil/) which offers completely silent running and a 40 km/h (25 mph/22 knot) top speed, along with the fast-turning the dynamics of a "sports car for the water."
One of the greatest advantages of the Quadrofoil is its lack of emissions and hence impact on delicate marine ecosystems. By comparison, most Personal Watercraft with the throttle wide open will burn a liter of gasoline per minute and dumping that quantity of burned hydrocarbons into a river or lake is unsustainable and unjustifiable in the long term.
Another advantage of the Quadrfoil over PWCs (and plus for the marine environment) is that in addition to being silent, it does not create a wake at speed, as it does not displace a significant amount of water.
Due to the remarkable efficiency of hydrofoils, it achieves its 25 mph top speed with just one 3.7 kW electric motor, and thanks to its lightweight (150 kg - 330 lb) carbon fiber and Kevlar body and in-built 4.5 kWh lithium batteries, it has a range of 100km (62 miles). It can also be recharged from a domestic powerpoint in an hour, or via the flexible solar panels which come with each Quadrofoil and are designed to be folded inside the watercraft as an emergency power source, or to top up the battery when "off the grid."
Though the term hydrofoil (http://en.wikipedia.org/wiki/Hydrofoil) refers to any fin, keel, rudder, flipper, wing or foil which operates in water, man-made or otherwise, it is commonly used for the wing-like structure mounted on struts below the hull of a variety of boats. It is also used to refer to the boat to which hydrofoils are attached.
The hydrofoil's efficiency comes from its ability to lift a boat out of the water during forward motion, reducing hull drag to near zero into the bargain. Without all that surface area upon which turbulence and drag can act, there's only the much smaller surface area of the hydrofoils and aerodynamic drag to limit top speed.
This means the speed of a boat equipped with hydrofoils is either greatly increased (http://www.gizmag.com/new-world-sailing-boat-speed-record/10659/), or the amount of power required to propel it is greatly reduced, in comparison to a boat that does not have hydrofoils.
It is hence not surprising that the world sailing speed record (http://hydroptere.com/en/the-sailing-boats/l-hydroptere-en/), and the human-powered water speed record (http://lancet.mit.edu/decavitator/) both belong to watercraft with hydrofoils.
Going one step further, the Slovenian team used biomimicry to develop the shape of the hydrofoils and claim to have been so successful that the foils create less drag at speed than the air resistance of the hull above the water surface!
Another benefit of a hydrofoil is the comfort factor for passengers - as once the hull has been lifted above the waves, the incessant pounding disappears and the boat feels like it is flying. Indeed, a hydrofoil is a wing that "flies" in water, and the flight of the Quadrofoil is only disturbed by waves greater than 20 inches (50 cm).
The designers claim the Quadrofoil is unsinkable, and it is designed to always return to upright should you manage to overcook it in a tight turn.
One of the key enablers of the machine was the development of a hydrofoil-folding mechanism, which enables the six kilogram hydrofoil legs to be adjusted during use, and to be folded upwards by means of a manual or electric winch before entering a swimming area or approaching shore. Once the hydrofoil legs have been turned upwards, the Quadrofoil has a draft of just 6 inches (15cm).
The folding legs can also be removed, making for an easily transportable machine at 150 kg and 10 feet (3 m) in length.
Due to the low power of the 3.7 kW motor, the Quadrofoil belongs to a category of watercraft that does not require registration, a PWC license, insurance or navigation permit in the EU.
The future looks bright for the Quadrofoil and already development of a much faster machine is underway. The current foils are suitable for speeds up to 80 km/h and, in cooperation with Fakulteta za Energetiko (Faculty of Energy Technology) in Krškothe, the company is developing its own outboard motor and propeller with variable pitch which it believes will be one of the most efficient in the world. The propelor and 12 kW outboard will be ready later this year, presumably meaning that a version will be available in the not-too-distant future with a top speed more than double the current version.
From a recreational craft through to a silent, fast craft for special forces, the Quadrofoil looks to have every chance of commercial success. Distribution, dealership and investment inquiries will be welcomed from all countries according to the company. Source: Quadrofoil (http://www.quadrofoil.com/en/)

THE FOILJET MR1
February 10, 2009 The Foiljet MR1 is a new personal watercraft concept that takes the best features of a motocross bike and jetski, throws in two hydrofoils plus a silent, energy efficient electric motor to create what would have to be a surefire recipe for outrageous fun. The design looks something like a motocross bike, but instead of wheels there are beams with small hydrofoil wings mounted at the ends that can be raised or lowered. The concept would use a 15 kW (20 hp) electric motor housed at the end of the rear beam with its instant electric torque lifting the craft out of the water to become "foil borne".
To cope with shallow water the beams can be raised at the flick of a switch. The electric motor runs off a 48V battery that should see three hours of full load running with the possibility of a theoretical 10 min recharge time.
While still at the purely concept stage Matt De Bellefeuille (http://www.debelle-design.com/) & Robert Vandenham have come up with an original design that most definitely deserves to reach the prototype stage.
The designers have selected a T-shaped fully submerged foil system which, while not affected by surface waves is not self stabilizing, so it needs constant adjustment of the angle of attack of the front foil to keep the craft level with the surface. Front foil angle adjustment on the Foiljet MR1 is made manually by what would conventionally be the clutch lever on a motorcycle. In larger applications this sea-keeping function is automated with a computer system that measure either surface height or pitch and roll to make constant fine adjustments to the front foil.
Hydrofoils produce relatively no wake and electric propulsion is near silent, so if the Foiljet MR1 makes it into production it may allow current laws against jetski’s on inland water ways to be relaxed around residential areas.

February 22, 2007 Recreational vehicles will come in many different forms in the future as a raft of developing enabling technologies spawn new categories of technologically-enhanced ground, water and aircraft – not only are these traditional categories splintering, but there are new variations of toys for big boys, some of which will develop their own categories – craft like the part boat, part sled, part ground-effect Tupelov aerosan (http://www.gizmag.com/go/6433), the Bionic Dolphin (http://www.gizmag.com/go/4095/) and Sea-Breacher (http://www.gizmag.com/go/6542/), the SeaPhantom (http://www.gizmag.com/go/6835/), a host of recreational submarines such as Deep Flight (http://www.gizmag.com/go/1890/), the amphibious Quadski (http://www.gizmag.com/go/5682/) and the list just goes on and on of new RVs that break out their own category. One emerging area of enormous promise is that of powered ground-effect RVs – we’ve already seen human-bearing inflatable towable water kites such as the Kite Tube (http://www.gizmag.com/go/5750/) and the Manta Ray (http://www.gizmag.com/go/5795/) and the now dormant Sharkski (http://www.gizmag.com/go/2287) but with light weight, high power and computer-aided design, the concept of an affordable powered ground-effect vehicle for under US$50,000 is within reach. The Skimmer is a small jet-ski like ground-effect airplane that starts in the water and can be flown over sea, rivers and lakes, steered partially by handlebars and partially by moving one’s body weight, similar to the way a motorcycle is ridden.
With a maximum speed of 100 km/h and maximum flying height is 1.5 metres, the Skimmer offers maximum excitement and minimal fuss, because no flight papers are necessary. Dutch product designer Roel Verhagen originally conceived the Skimmer concept as an entrant in the 2005 Braun Prize.
“Wing-in-ground effect has been in use from as early as the 1930’s,” says Verhagen. “Russia was even building enormous airplanes from in the early 1950’s using the same principles. The triangular shape of the wing with T-tail was invented in 1965 by Alexander Lippisch and makes for greater stability.”
“I’m also a fan of the Wankel engine which Felix Wankel invented in 1957 and has been developed and improved upon ever since. The wankel engine is being used in the Mazda RX-8 and the Moller Sky Car (http://www.gizmag.com/go/1378/), which uses no less then eight wankel engines, and Mazda’s work with Hydrogen fuel in the wankel was the deciding factor.
“These known techniques have been getting some renewed attention lately as there have been some new technological developments.
Innovations in the fields of materials knowledge and production techniques have been improving on the performances of, and make it possible to build lighter constructions."
Verhagen is now seeking partners in his project. “For the next step in the development from concept to product, a lot of expertise will be needed. First, the 3D model will need to be evaluated and optimized with the use of simulation software. Then, a radio controlled scale model will have to be built, to test and prove the theory. When this is succesfull, we will be looking for a partner with enough resources, experience and facilities to produce a full scale prototype and, eventually, start up serial production.
Roel Verhagen can be contacted here (email@example.com).

In order to surf those massive walls of salt water known as big waves, brave surfers usually need to get towed in by a personal watercraft (PWC). This presents some logistical problems (i.e. having to bring a buddy along to tow you around all day). The WaveJet gives you the power you need without requiring a large tow-in vehicle or separate person.
The WaveJet is a personal water propulsion (PWP) device that adds a little motor power to paddling. Unlike the JetBoard (http://www.gizmag.com/go/3871/), which harnessed motor power in the ride itself, the WaveJet has the more modest objective of getting you to the ride. It lets you paddle up to four times faster, giving you the speed and power you need to catch a big wave without a buddy riding shotgun.
The WaveJet itself is a pod that's designed to fit quickly into WaveJet-ready boards of all kinds - surfboards, paddleboards, boogie boards and rescue boards. It fits flatly against the bottom of the board, so it doesn't interfere with your ride and uses two aluminum impellers to give you up to 20 lbs (9 kg) of thrust and 12 mph (19.3 km/h) of speed.
The surfer controls the output by way of a wireless remote control worn on the wrist. The wireless system keeps the surfer's hands free and doesn't tie him to the board. The wristband also monitors battery level and cuts propulsion off if the surfboard gets more than a leash length away from surfer. The rechargeable lithium-ion battery gives you 30 to 45 minutes of run time, and since you're not actively using it the entire time, that translates to much more actual time on the water.
WaveJet inventor Mike Railey enjoyed tow-in surfing when he first tried it back in the late 90s, but didn't like the hassle of having to rent out a tow-in vehicle. The existing motorized boards were too heavy for his liking, so he got to tinkering on the compact, lightweight add-on that became known as the WaveJet. After receiving several patents for the model, Railey introduced WaveJet last year. Surfers, professional lifeguards and other industry professionals have been testing it, and the first commercial run will hit the market next month. The WaveJet will be offered in surfboard, boogie board and stand-up paddle board varieties this year, with kayak and other models to follow next year.
Big wave surfer and WaveJet ambassador Garrett McNamara was using a traditional tow-in system when he set the world record for biggest wave (90 feet/ 27.4 m) ever surfed last November, but he did use the WaveJet to catch a 50-footer (15.24 m) on the same trip to Portugal.
While WaveJet was inspired by big waves, the system is also useful beyond surfing. When used in rescue boards, it allows lifeguards to get to victims more quickly while conserving energy. Serving as a lightweight motor on a kayak or boat, the WaveJet's flat design means it doesn't need any clearance and can be used in shallow water. It can also help boaters to battle strong currents.
WaveJet deliveries will begin in mid May. The WaveJet pod retails for US$2,500 on its own, for use with WaveJet-ready or retrofitted boards. Recreational board packages start at $4,395, and rescue board packages at $4,150. Pre-orders involving a $500 deposit are open now.
The video below shows what the WaveJet is all about.

Deluxe jetski model
These photos show different conceptual graphic designs as well as options considered by Kawasaki for a production Deluxe model Jet Ski. The horn was a pretty obvious FAIL. From Vintage Jetskis
The Deluxe Model
This photo shows a unique handle pole hinge plate that incorporated a headlamp. The Deluxe model also sported a chrome exhaust nozzle. The "EV" represented "Experimental Vehicle"
The horn would fill up with water in a second, and the light itself would create a blinding strobe effect with the hull bouncing around and reflecting off the bow spray.

Here is another Conceptual Prototype design by Kawasaki. It was never produce. The bow rise is more noticeable and a deeper V Hull. The seated position and helm position are notable. This concept was never a production model. You can see the origins of what would later become the 'Sport' Model X-2 Jetski. Notice the bow rise and deeper V Hull design.

The First Double amputee rider. Meet Dale Veedy. He is 76 years old. This is taken in the year 1977.
From time to time Vintage Jet Ski facebook page receives photos of some truely inspirational people. Ralph Veedy, a watchmaker from Bellflower, CA. really worked it out on this '77 JS440. At the time this photo was taken, Ralph was 76 years old. But even more cool, Ralph could outride a lot of guys... even without legs.

This hull, known as "Alien" is believed to have been fabricated by Clayton Jacobson II back in the late 70's or early 80's. The hull and hood are hand laid fiberglass while the pole is a stock 550 from a later year JS. His son, CJ3, informed us that very few Alien hulls were ever made (8 to 12) and were done so for the use in the surf. Differences from a standard JS model include huge chines, a deeper pump cavity, narower draft, teardrop shaped tray, rounded rails, shorty nose and a lightened louvered hood.

The 650 didn't come along until much later and the Jet Ski concept / sales were very scetchy in the early years. It wasn't until Bob Montgomery came along and pushed sales and marketing outside of the motorcycle shops-Vintages
These units were graphic tests only
Each side had different graphics. The 650 was a long way off as these pics are 73-74. In 1974 Kawasaki did make a two person sitting jetski test boat and it had the 600 engine in it.
This ski was a concept used for graphic only. Both sides of this ski had different graphic designs that were created by Al Shimosaki who worked for Kawasaki back in the 70's. This was one of his designs.
"Sukiaka Japan or sumthing...one off proto type...Animal,one of the first test riders..took it out of the box late at night... a full moon...on Snug Harbor glass...and I was there.whole different motor..story was a test rider in Japan was killed on it...love story's....then it was s****ed...back in 1975...and a half."

FROM IJSBA HALL OF FAMER CHRIS LAUBER
From the earliest days of the IJSBA, when the sanctioning body was still in its formative stages, from April 12, 1982, this letter is from Executive Director Dave Severson to my borther Mark. At the time, we had staged 8 Jet Ski races in Florida, including the first one anywhere in the world outside California on August 12, 1979. This letter provides a glimpse into some of the details in starting the IJSBA and Jet Ski racing. Enjoy!
This is the beginning of JETSKI Racing. It is a historical document for the sport. Thank you Chris Lauber for sharing this with everyone!

Aqualeo is a company founded by Jeremy Benichou, an engineer who saw a market between the Jet Ski and paddle boat with an electric water go-kart.
In two years, his company Aqualeo developed the Gliss-speed a small electric boat that achieves speeds up to 25kph (15 knots).
Very simple to operate the Gliss-Speed is a hull, an electric motor with a propeller, a fin and a removable battery located in the front (the battery compartment is protected by a double sealing).
A control panel allows to start the Gliss-speed on/off/init and select the drive, forward/neutral/reverse.
The controls are located at the handles for the direction, use the levers to go left or right, the accelerator is in turn under the right foot.
SPECS OF THE GLISS-SPEED (http://www.technologicvehicles.com/en/details/1796/aqualeo-gliss-speed-prix-et-fiche-technique)
Most of the Gliss-speed sales are on the export market for now, it is available in Dubai and soon in Thailand.
Originally the set-up is friendly and safe, but the gliss-speed can be modified to suit a variety of uses, fin, motor control, battery size, anything is possible!
In use, like any electric vehicle torque is impressive and the boat literally takes off at the first push of the accelerator the controls are intuitive.
How and where to use it, ideally on a lake with a small circuit with at least two people, the winner may be the one who arrives first or least wet, it’s up to you! <!-- / message --><!-- sig -->
