发明名称 Human propelled buoyant annular float with removable pontoon stabilizer
摘要 A buoyant apparatus for transport or amusement which is propelled by a human operator in a standing position. An annular float has a platform secured to its upper side and a plurality of circumferentially spaced fins extending from its lower side. Struts with pontoons are removably connectable to a rotatable mast which extends through the platform. When a human operator strands on an outer ring portion of the platform, the pontoons float in the water and stabilize the annular float in an inclined position, raising the fins on one side of the float out of the water. When the operator walks forwardly, counteracting the torque by holding a paddle against a strut, forward propulsion results. When sufficient skill is acquired, the struts and pontoons are disconnected from the mast, and the operator drags the buoyant paddle in the water to provide balance and counteract torque sufficiently to result in forward propulsion.
