Powered by an electric motor and a small propeller hidden beneath the board, this tiny, remote-controlled surfer can hit speeds upwards of 16km/h even without a wave pushing it along. But with a rushing wall of water behind it, Mother Nature decides its top cruising speed.
Whoever's holding the wireless remote always remains in control of the surfer, however, no matter how fast it's going, thanks to a servo-steered pair of rudders on the bottom.
Can you really call yourself an extreme athlete when you're letting a foot-tall plastic surfer take all the risks for you? Probably not. But for around $US230 ($303) you're guaranteeing you won't end up in a body cast after a weekend on the water -- or worse.
