How does the Watt&Sea hydrogenerator operate?

The principle is simple: Watt &Sea hydrogenerator uses the speed of the sailboat to turn an immersed propeller. Like the dynamo of a bicycle rubbing on the wheel the propeller in contact with the water flow produces electricity. Energy production begins at a mere 3 knots of hull speed (Cruising model).
