  • Power boat hull
    Patent number: 5476061
    Abstract: A power boat hull has an inner running surface with a central running surface and an outer running surface that flanks the inner running surface. The outer running surface forms a channel with concave curvature which extends from the bow to the stern. An improved channel is shaped so that pressure builds in the channel during turning of the boat to lock the hull to water throughout the turn. A transom is provided with a deflector plate having a curved surface that is lifted out of the water during high speed running of the boat and operatively deflects water downward to force the bow of the boat into the water during low speed running of the boat. The transom dimensions are altered to accommodate varying length boats.
