This class was limited to motorboats exceeding 6 metres but less than 8 metres in length, weighing not less than 800 kg. without fuel or crew, and with a total piston area not exceeding that of four cylinders, each of 106 mm. bore. This race was very close until the Sea Dog was forced to stop due to a "hot bearing."
