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.

New technology has enabled current PWC models to meet EPA's 2006 marine engine standards years ahead of schedule; they are among the most environmentally friendly motorboats on the water today. All five PWC manufacturers offer personal watercraft with four-stroke engines in model year 2003. Lake Tahoe-which has the strictest environmental requirements in the country-welcomes the use of more than 30 models of direct-injection, and four-stroke personal watercraft because they are uniquely environmentally friendly.
