- "A motorbike that you can drive on water drunk while churning up a fragile ecosystem? Yes please. The Seashark was 2011's #1 boytoy among the douchebag and mid-life crisis demographic. There are few things more fun than over-revving a Seashark up and down the shoreline, and it's a real treat for all the people who've come to the beach to relax."
- ―DockTease description.
Unlike the Jetski, the Seashark is not the fastest watercraft, it has a excellent acceleration and good top speed, but its top speed can be easily beaten by the Speeder and the Jetmax, but it makes up for its handling, with a very small turning radius and excellent maneuverability.
