| 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 names Jetski or Sea-doo, which are brand names owned by Kawasaki and Bombardier, respectively.
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.
Some surfers use personal watercraft to get to the waves and get up to speed with them; this is known as tow-in surfing. They can also be used for towing water skiiers on flat water.
