Jet Ski

Jet ski is a boater-cycle, is a primarily recreational watercraft that is designed to carry a small number of occupants, who sit or stand on top of the craft, not within the craft as in a boat. It has two style groups. The first and the most popular is a compact runabout, typically holding no more than two or three people, who mainly sit on top of the watercraft as one does when riding an ATV or snowmobile. The second style is a "stand-up" type, typically built for only one occupant who operates the watercraft standing up as in riding a motorized scooter; it is often used more for doing tricks, racing, and in competitions. Both styles have an inboard engine driving a pump-jet that has a screw-shaped impeller to create thrust for propulsion and steering. Most are designed for two or three people, though four-passenger models exist. Many of today's models are built for more extended use and have the fuel capacity to make long cruises, in some cases even beyond 160 kilometres (100 miles). Personal watercraft boat conversion kits exist as Waveboats.
