ABSTRACT:
A multi-hull marine vessel having a center hull and a left and right outer hull movably positioned adjacent to the center hull. The outer hulls are on opposite sides of the center hull and are generally parallel to the center hull. Extendible support assemblies extend between the center hull and the outer hulls. The extendible support assemblies are movable between a retracted position with the outer hulls in nested positions immediately adjacent to the center hull, and extended positions with the outer hulls in outward positions away from the center hull. A support moving device is connected to the extendible support assemblies and is positioned to move the extendible support assemblies between the retracted and extended positions, thereby moving the outer hulls between the nested and outward positions. The center hull has a water ballast tank therein that is adapted to be filled with water, such that the multi-hull vessel is a self-righting vessel that will right itself from an overturned position when the water tank ballast is filled and the outer hulls are in the nested position. The outer hulls are sealed hulls with positive buoyancy to provide an unsinkable, ballasted, multi-hull marine vessel.
