Anti-drift device for naval boat, has anti-drift centre-board that is laterally inclined in such manner that it maintains quasi-vertical position irrelevant of angle of keel of boat

摘要

The device has an anti-drift centre-board (1) laterally inclined in such a manner that it maintains a quasi-vertical position irrelevant of an angle of a keel of a boat. The centre-board is inclined by utilizing a flap (6) whose rotation is horizontal and is aligned in a longitudinal axis of the boat. A control cage (8) guides the centre-board during lowering or raising and maintains the centre-board in its high or partly low position. An independent claim is also included for a naval boat including an anti-drift device.
