A watercraft is powered by a user sitting on a sliding seat and using footrests. The user operates a simulated rowing mechanism which includes a handle, cord, and reel. Power is transmitted through the rowing mechanism to a series of paddles, which move in a loop in a horizontal plane through the water underneath the watercraft. The paddles are mounted on a belt that passes around front and rear wheels. The paddles are feathered when moving forwards, by means of followers and/or a cam surface.
