ABSTRACT:
The boat hull includes a hull body having an upper surface and a lower surface. The lower surface of the hull body is divided into a fore portion, a central portion and an aft portion, with a central recess being formed in the central portion and an aft recess being formed in the aft portion. The central recess has a substantially V-shaped cross-sectional contour having a height and a width that both increase in the fore-to-aft direction. The aft recess has a substantially rectangular cross-sectional contour and is in communication with the central recess. The aft recess extends in the fore-to-aft direction from a rear edge of the central recess to an aft edge of the lower surface of the hull body.
