A performance jet ski is due to appear in Grand Theft Auto VI, seen docked beside a red Seashark in the first trailer and riding a Bison-towed trailer in the second. Its front fairing is far more aggressive than the Seashark's, appearing to blend the Sea-Doo RXT-X 300 with Yamaha WaveRunner styling.
