  • High-speed lateral-stability hull construction
    Patent number: 5425325
    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.
