ABSTRACT:
A power boat hull having sides and a bottom formed of a series of vertically stepped panels disposed symmetrically on either side of the hull center line. The series of panels on either side of the hull center line include an inboard panel, a center panel and an outboard panel. Vertical risers join the adjacent edges of the center and outboard panels and extend substantially parallel to the hull center line. Vertical risers join the adjacent edges of the center and inboard panels and extend on opposite sides of the hull center line from the stern to a point of intersection on the center line adjacent the bow. The panels are angled upwardly from the horizontal, outwardly of the hull center line with such angularities decreasing between successive panels in the outboard direction at all stations along the length of the hull except at the stern, the angularities of each inboard and center panels increasing from the stern toward the bow while the angularities of the outboard panels remain constant.
