Abstract
A boat configured for rotating in response to passenger inputs such as rotation of a wheel or pumping a hand pump. The boat includes a hull with an upper portion for receiving at least one passenger and a lower portion comprising a bottom contact surface. Further, the boat includes a rider interface, provided on the upper portion of the hull, that is configured for receiving physical input from the passenger. The boat also includes a torque producing assembly with a boat-to-water interface provided on the lower portion below a waterline region and above bottom contact surface. The boat-to-water interface applies a force to water adjacent to the lower portion of the hull in response to the received physical input, whereby the boat rotates due to a resistive force applied by the water in response to the applied force.
