A rigging and sail system for a sailboat including a rotatable mast having mounted thereon for rotation therewith, a pair of upper and lower booms extending transversely of the mast. The booms are connected to the mast through upper and lower tension members extending between the mast and the outer ends of the booms respectively and vertical fore and aft tension members extending between outer end portions of the booms on opposite sides of the mast. A pair of sails such as a main and jib are sheeted to and between the booms on opposite sides of the mast to be movable with the booms relative to the hull, and with the jib being movable relative to the booms to allow self-tacking during use merely upon steering the sailboat across the wind. The booms also provide horizontally extending air barriers above and below the upper and lower horizontal edges of the sails respectively to prevent or reduce loss of air across the sail edges while also channelling the air to flow horizontally along the surface of the sails in the fore-aft direction. In one embodiment, the main sail is attached at its leading edge to a furling sleeve received about the mast for rotation to allow furling upon rotation of the sleeve. The leading edge of the jib is attached about the fore tension member or about a furling sleeve rotatably received about the tension member. Several other embodiments are disclosed.

A rigging system for sailing craft such as a sailboat comprising in combination: a mast, upper and lower booms mounted on the mast and extending transversely relative to the mast and being adapted for rotation together as a unit about a generally vertical axis extending through the mast when mounted on a sailing craft, means interconnecting the booms and the mast including upper and lower tension members extending between the mast and the booms at locations above and below the upper and lower booms respectively, and fore and aft tension members interconnecting the upper and lower booms on opposite sides of the mast, said upper and lower tension members and said fore and aft tension members being rotatable with said booms as a unit about said vertical axis, and wherein the upper and lower booms are spaced from each other for accommodating a sail to be sheeted to and between the upper and lower booms, and wherein the tension members are under tension and the booms and mast are under compressive forces from the tension members acting longitudinally through the booms and mast.
