ABSTRACT:
A boat hull has an aft swept ventilated area in at least a part of its bottom planing surface. An aft swept water flow interrupter is positioned to project downwardly from the hull forward of the ventilated area. The aft swept flow interrupter has two generally angularly related legs or sections defining a 30° to 70° included angle, increase lift on the hull, reduces wetted surface area and improves the turning characteristics of the hull.
