Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
A power boat hull having sides and a bottom, said bottom being formed of a series of vertically stepped panels disposed symmetrically on either side of the hull center line, said series of panels on either side of the hull center line including an inboard panel and a center panel and an outboard panel, vertical risers joining the adjacent edges of said center and outboard panels, vertical risers joining the adjacent edges of said center and inboard panels and extending on opposite sides of the hull center line from the stern to a point of intersection on the center line adjacent the bow to provide soft riding qualities, said panels being 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 said inboard and center panels increasing from the stern toward the bow while the angularities of said outboard panels remain constant thereby stabilizing the hull both while running at all speeds and at rest.
