Surfing is a surface water sport in which a person (the surfer) rides a board (the surfboard) on the crest of a wave as it carries the surfer towards the shore. Two major subdivisions within stand-up surfing are long-boarding and short-boarding, reflecting differences in surfboard design including surfboard length, and riding style.
In tow-in surfing (most often, but not exclusively, associated with big wave surfing), a motorized water vehicle, such as apersonal watercraft tows the surfer into the wave front, helping the surfer match a large wave's higher speed, a speed that is generally, but not exclusively a speed that a self-propelled surfer can not match.
