Some personal watercraft can carry as many as three passengers. Many emit a spout from the rear when underway.

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.

What about PWC emissions? Some anti-access groups cite a study that compared an unregulated old-technology PWC with a regulated 1998 model car, which is an apples to oranges comparison. The fact is, with the introduction of "new-technology" engine improvements such as catalysts, direct injection, and four-strokes, marine engine manufacturers have achieved a 75 percent reduction in hydrocarbon and NOx emissions in a matter of years, as opposed to the decades it took the automobile industry to achieve the same reductions.

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.
