A watercraft having a hull, a fore and aft longitudinal axis and a bow includes a three dimensional low drag submerged lifting body secured to the bow below the design waterline of the hull.

Bow lifting body

Low drag underwater submerged lifting bodies which can be used as underwater displacement portions of a vessel whose main hull is at sea level are asymmetrical and have improved lift to drag ratios. The lifting bodies have outer surfaces whose shapes are defined in plan and elevation by generally parabolic curves which are different on opposite sides of the lifting bodies.
