Abstract
A surfboard which is convertible from unpowered to motorized condition by the selective movement of a motor mounted in the elongated buoyant float member. Movement of the motor along the longitudinal axis of the float member does not substantially alter the floatation characteristics of the surfboard. Hand grip elements and a windshield are detachably connectable to the float member for use by the surfboard rider in a prone position during motorized operation.
