Andrew Hall's Stirling Engine Boat

Andrew Hall's Stirling Engine boat at Beale Park Boat Show, June 2013. Engine originally built by Norris Bomford. Propane burners. Small 12V electric water pump pumps river water through the engine for cooling. Speed about 3-4mph. Designed for UK rivers and canals where the speed limit is 5mph. Direct drive from engine to propeller. Two rudders to steer and brake (pulling both rudders so they are at right angles to the propeller).
