ABSTRACT:
A boat with a unique hull that stabilizes watercraft during turning conditions in water, thereby substantially reducing or eliminating the side-to-side oscillation that is typical of prior art craft undergoing this maneuver. To achieve this enhanced stability, the hull has a series of ridges or troughs, or both, to disrupt laminar flow along the hull, when the craft turns. This disruption of laminar flow stabilizes the hull and substantially eliminates side-to-side oscillation.
