  • Shallow draft boat with a tri-tunnel hull
    Patent number: 7448927
    Abstract: A shallow draft boat has a hull that protects a propulsion propeller within a tunnel that passes only partially through the hull from stem to bow. The hull causes mixing of water and air at high pressure during motion of the boat through the water, creating lift and a pressure gradient that keeps the tunnel filled. The boat prevents propulsion unit malfunction by keeping obstacles, such as debris, crab pots and mammals such as manatees from contact with the propeller.
