ABSTRACT:
The invention includes new hull systems and watercraft. In particular, the invention provides a watercraft hull that has a pivot axis forward of the hull waterline fore-aft center line. That pivot axis will be the deep water point of the hull and provides a fulcrum point around which the hull turns during a direction change. The forward pivot axis surprisingly imparts high maneuverability (i.e. the ability to execute turns of reduced radius) relative to prior systems, even at low speeds.
