Not everthing is original. But it had to start somewhere!
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.

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.
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 and WSAB, 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 and WSAB could be distinguished by their hulls: the WSAA featured a flat hull, while the WSAB 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. 1977
Market demands for more power lead to development of the JS440, an upgraded version of the popular JS400. The JS440 offered more performance and became one of Kawasaki''s longest selling models, enjoyed equally by fun-lovers and racers.

The JS550 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 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. 1986
The lightweight JS300 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 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 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 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 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 featured a new V-hull design that increased stability during boarding and during high-speed manoeuvring. 1989
The Kawasaki JET MATE 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 SportTM, 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.
