Patent ID: 10017233

Abstract:
A jet-powered oar system for a paddleboard designed to help paddle boarders travel long distances without feeling fatigue includes a propulsive oar and a restraining mechanism. The propulsive oar propels the paddle board without physical input from the paddle boarder. The restraining mechanism retrofits onto an existing paddleboard and retains the propulsive oar. The propulsive oar utilizes an oar shaft, an oar paddle, an impeller pump assembly, a primary battery pack, a kill switch, and an attachment collar. The oar shaft and the oar paddle can be used to physically propel the paddle board. The impeller pump assembly permits motorized propulsion of the paddle board when the paddle boarder succumbs to fatigue. The primary battery back stores electrical energy for powering the impeller pump assembly. The kill switch stops the paddle board from moving. Finally, the attachment collar couples the propulsive oar onto the restraining mechanism.
