The Superjet is a personal watercraft (PWC) made by Yamaha Motor Corporation. The Superjet is a "stand-up" PWC. Credit for its design is given to Clayton Jacobsen II. Part of their WaveRunner line of watercraft, it was introduced in 1990 and has become one of the most popular personal watercraft in history. The latest 2010 Yamaha Superjet is ridden by the professional freerider Ross Champion.It is common to see the Yamaha Superjet flying high doing the back flip or barrel roll.Riding the Superjet surf style is now a lost art as there is no progression in this area at competition level.

Current Superjet

The current Superjet (still in production by Yamaha Motor) has been visually the same since 1996. The 2008 model was the first year of a new bottom deck, previously unchanged in the history of the superjet. This watercraft does not meet California or New York emissions standards.
