Jet ski is the brand name of Kawasaki Heavy Industries personal water craft. The name, however, is often used as a generic term for other makes of personal watercraft, typically those propelled by rapidly expelling water behind them in a jet, rather driven by a screw-shaped propeller.
Because of their relatively low cost they are widely used on water bodies across the world. Whilst they can be used responsibly and with concern for the natural environment, they are also used with a disregard for safety, without consideration of those experiencing their noise, and ignoring potential environmental impacts. As a result there are pressures in many parts of the world for regulation in the use and management of such craft.
