  • Means for decreasing wave resistance on marine vessels
    Patent number: 4359010
    Abstract: A marine vessel has a hull which is provided at the stern part thereof with a propeller. In order to decrease the wave resistance at the stern part of the hull, it is provided with a wave generating member which extends aft beyond the aftermost point of the full load water line. The member produces waves which are opposite in phase to and interfere with waves as produced at the stern part of the hull whereby the waves can at least partially be cancelled.
