A personal watercraft (PWC) is a recreational watercraft that the rider sits or stands on, rather than inside of, as in a boat. Models have an inboard engine driving a pump jet. They are often referred by the name Jetski, which is in fact a brand name owned by Kawasaki.
Most are designed for two or three people, though four-passenger models exist. Stand-up PWCs are also popular for single riders, offering a more challenging and "extreme" ride.
