The present invention entails a canting sailboat sail rig. Mast support struts are attached at one end to the outer edges or railings of the hull(s), to the stern of the mast, and the mast struts attach at the other end to the lower sections of the mast. The mast foot base is attached to a circular track that runs from the centerline of the sailboat outward, toward the edges of the hulls, and upward the bow(s). When the mast foot move outward and upward toward the railing and bow(s) the upper section of the sail tilts or cants in the opposite direction from the mast foot outward direction, creating forward thrust, lift and reduced heeling. A jib can be attached to the head of the mast and the combination canting mainsail and jib can create force, lift and less heeling. |

1. A canting lift creating sailboat sail rig assembly, comprising:
a. a mast base circular track located approximately ⅔rds a distance from the stern to the bow(s) that runs from the stern to bow(s) center line of the sailboat outward and toward the outer edges of the hull(s) with the outer ends of the mast base circular track curving toward the bow(s); and b. the lower end of the mast, or mast base, is coupled to the mast base circular track; and c. mast rigid supports or struts are attached to the outward sides of the hull(s) sternward from the location of the mast base circular track; and d. the other upper ends of the mast struts are attached to the mast at about ¼th to ⅙th the length of the mast distance up the mast from the sailboat hull(s) deck; and e. the mast struts help hold up the mast and support the mast weight, lateral, downward and upward pressure put on the mast; and f. the mast strut's support allow the mast to be able to move along the mast base circular track; and g. as the mast base is moved while sailing or sailboat stationary, outward from the stern to bow centerline of the sailboat coupled to and moving along the mast base circular track, the mast struts rotate downward toward the bow and the upper section of the mast, the section of mast that is above the attaching point of the mast struts attachment to the mast, tilts or cants aft ward and outward in the opposite direction the mast base moves along the mast base circular track; and i. a sail, or mainsail, with or without a horizontal supporting member, or boom, is attached to the mast; and j. a line, or mainsheet, is attached to the mainsail or the mainsail boom; and k. the pulling in or letting out, trimming, of the mainsheet controls the angle of the plane of the mainsail relative to the longitudinal axis of the mast in line with the stern to bow centerline of the sailboat; and l. the combination of the mast, with attached mainsail, simultaneously tilting or canting aft ward and outward along the mast base circular track and the pulling in and letting out, or trimming the mainsail sheet, controls the forward thrust and lifting forces of the wind on the mainsail, and the degree of heeling of the sailboat. |
