Jet skis are vessels with a rigid hull, small (less than 4-metres in length), propelled by an inboard turbine motor, although there are also versions with outboard motors. Recently, they have been classified as the most environmentally friendly motor boats on the market due to the low-emission propulsion system. Various types of watercraft can be found on the market, personal jet skis or multi-seat runabouts and with various engine sizes.
Jet skis are lightweight, compact and versatile and have a handlebar like a motorbike. They can be driven sitting or standing and their rapid acceleration gives unbeatable sensations to all who want to fun in the water or who want to reach those more secluded places that most boats can not access. To ride a jet ski, depending on the power of its engine, a specific licence must be obtained, the Personal Watercraft Certificate. The latest generation of watercraft are becoming faster, and more environmentally friendly, as well as more powerful and quieter.
