Surf's not up? Chill, dude; the PowerSki Jetboard makes its own waves. Driven by a two-stroke engine that generates 350 lbs. of thrust, the Jetboard can carve up even the glassiest surface in a sport that combines the ease of water skiing with the freedom of surfing. The award-winning engine, designed by a 53-year-old former pro surfer, weighs only 30 lbs. and is just 6 1/2 in. high. A flexible pole in the bow controls speed and direction. It also houses a speedometer, fuel gauge and kill switch.
