摘要： An improved hull is disclosed for use on an inboard boat of a relatively increased length, the hull having a generally deep V-shaped bottom surface at the bow slowly transitioning to a relatively flat stern to provide increased lift as compared to conventional inboard boats, to provide a smooth ride yet permit maximized speed and stability for water skiing use, to provide the desirable handling characteristics (such as for turning and maneuverability) found in an inboard boat of relatively shorter length, and to produce a minimal wake for water skiing purposes. The hull is formed with a series of longitudinally-aligned pairs of strakes which, over the majority of their respective lengths, have a negative strake angle. Through the specific placement, the longitudinal commencement and termination, of the respective pairs of strakes, they provide increased lift, improved turning ability, and reduced wake side spray. A progressively-changing deadrise angle is formed into the hull which angle, from bow to stern, generally decreases from approximately 35.degree. relative to horizontal to approximately 9.5.degree..
