The contestant lies on a bodyboard at a starting line in the sea. On go, the board is pulled along by a speedboat.
The contestant has to try and stay on the board as it is pulled through two lines of buoys, and then up over a ramp. If they manage to hang on, they then have to wait until they reach a floating finish platform and leap off onto it.
If the contestant lands safely and stays on the finishing platform they win; but if they fall into the water at anytime they lose the game.
The boat pulls the bodyboard at varying speeds. Sometimes it moves extremely fast, but other times very slowly, so good balance is needed at all times.
