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 Jacobson II. Part of Yamaha's WaveRunner line of watercraft, it was introduced in 1990 and has become one of the most popular stand-up personal watercraft in history.
