The Stingray is a single-rider watercraft designed for both recreational and humanitarian uses. The buoyant saddle and lever combination is driven by a pneumatic propulsion system that converts user generated energy into air flow, transmitting thrust directly into the water without the use of gears or electric circuits. Useful as a mobile flotation device for flood disasters or simply to enjoy a day out on the water!
