High stability trimaran

A trimaran comprising:

• an elongated main hull, a starboard hull, and a port hull, the starboard and port hulls disposed on opposite sides of said main hull and parallel thereto;
• a mast;
• stays extending between said mast and said main hull for stabilizing the position of said mast with respect to said main hull;
• and means for operatively attaching said starboard and port hull to said main hull, for operatively attaching said mast to said main hull, and for operatively attaching said mast to said starboard and port hulls, so that the angle of inclination of said main hull is minimized and so that the trimaran is self-righting;
• said means for operatively attaching said starboard and port hulls to said main hull comprising means for pivotally mounting each of said starboard and port hulls to said main hull along a side of said main hull so that said starboard and port hulls are pivotal about an axis generally parallel to the direction of elongation of said main hull;
• said means for operatively attaching said mast to said main hull comprising means for pivotally mounting said mast to said main hull so that it is pivotal about an axis substantially parallel to the axes about which said starboard and port hulls are pivotal;
• and said means for operatively attaching said mast to said starboard and port hulls comprising shroud means.
