An efoil has a short board with an electric propeller that pushes you through the water. The propeller is located roughly two feet below the board on the mast. Attached to the end of the mast, is a “hydrofoil”, or wing. This is what makes the board fly. When the board gathers speed, the wing generates lift and the board and rider will fly above the water! Speed is controlled by a trigger throttle in a Bluetooth, hand-held remote. After liftoff is achieved, the rider finds themself to be quite stoked.
