  • Stabilizing fin for a motor boat
    Patent number: 4995840
    Abstract: Each stabilizing fin is provided with a thickened trailing edge in order to act as a flap for inducing drag during start-up. The induced drag serves to minimize the time within which the fin moves into a planing position. The recess on the bottom surface of the fin enhances the lifting force on the fin during stabilization without imposing undue drag forces during high speed travel of a boat.
