Power boat hull

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.

High-speed lateral-stability hull construction

Abstract: A single-body transom type of hull includes reaction flaps extending along side platings of the hull in a direction from bow to stern over at least 10% or more of the length of the ship. Inner surfaces of the flaps, along with outer surfaces of the side platings, form structures having inversely U-shaped cross sections defining recesses of parabolic cross sections so that water may flow smoothly along the hull. The reaction flaps thus suppress the outward flow of spray from the hull and impart lateral stability to the hull even at high speeds.
