Claim Text:
1. A hull for a watercraft having a length and a maximum width, comprising: a rockered keel area; a front lift surface; a back planing surface, wherein at least one portion of either or both said front lift surface and said back planing surface has positive camber in a longitudinal direction; and a main lift surface adjacent said rockered keel area and between said front lift surface and said back planing surface with a longitudinal position such that a center of dynamic lift of said main lift surface is at or in front of a point which is a fraction of said length of said hull behind a total center of gravity of said hull, wherein wherein said front lift surface and said main lift surface are separated by a step in one or more of hull depth and attack angle, wherein said back planing surface is longitudinally separated from at least a portion of said main lift surface ending in a step in one or more of hull depth and attack angle, wherein the front lift surface supports less than wherein a line running along the hull surface along the hull centerline from the front of said front lift surface to the middle of said main lift surface to the back of the back planing surface will have rocker or zero camber.
