DRIVANORDNING FOR BATAR

摘要

The whole propulsion mechanism of a boat including an engine 30 is assembled into a housing 37 which carries a propeller 31, thus forming a propulsion unit which may be manufactured and assembled independently of the boat. The housing 37 is received by a well 28 formed in the hull of the boat. The walls of the housing 37 and well 28 isolate noise and vibration of the engine 30. The boat is buoyant both when the propulsion unit is received in and removed from the well 28 and fitting of the unit requires no water-tight seals to be made. In preferred embodiments of the invention the hull is moulded from fibre-reinforced plastics material. In alternative embodiments the boat has a water-jet propulsion system. The housing may be circular and rotatable to effect steering.
