A sailing craft having a center hull, a port hull and a starboard hull. The port and starboard hulls are adjustably connected to the center hull by bridge beams such that the port starboard hulls may be disposed adjacent to, or outward from, the center hull. An inverted U-shaped mast has legs angled outwardly and connected to the port and starboard hulls when the mast is erect and legs which are substantially parallel when the mast is stepped down for storage on the center hull. A primary boom is rotatably connected to the center hull and rotates through 360°. An articulating boom is pivotally connected to each of the ends of the primary boom. A sail shape boom is connected to the articulating booms by a trolley on each articulating boom. The head of a sail is connected to the top of the mast and the foot of the sail is connected to the sail shape boom. The sail and booms are rotatable through 360°without contacting the mast. Sail lines connected to the edges of the sail are separated into support lines which are disposed over the surfaces of the sail and connected to wishbone spars to maintain luff and each alignment and control the sail shape by equal tensioning applied by the halyard.

A sailing craft having a center hull, the hull having a deck, a port side, a starboard side, a bow and a stern in a longitudinal plane, an amidships between the bow and the stern, the craft comprising: an outboard port hull and an outboard starboard hull, said hulls being adjustably connected to the center hull by respective port and starboard bridge beams, means for moving and securing said outboard hulls adjacent to the center hull for storage, transport and power sailing with an outboard motor, wherein said hulls are in a substantially vertical and seaworthy position and means for moving and securing said outboard hulls outwardly from the center hull for sailing; an inverted substantially U-shaped mast having a port leg and a starboard leg, said legs having a juncture at an arcuate top, and when the port hull and the starboard hull are disposed outwardly for sailing, the port leg being connected to the port hull and the starboard leg being connected to the starboard hull; a primary boom having a first end, an opposite second end and a midpoint, the midpoint of the primary boom being rotatably mounted approximately above the amidships of the center hull and between the port leg and the starboard leg of the mast, wherein the primary boom may rotate through 360°about a rotary axis in a plane parallel to the longitudinal plane of the center hull; a pair of secondary articulating booms, one pivotally connected to the first end of the primary boom and the other pivotally connected to the second end of the primary boom; a sail shape boom having a first end and an opposite second end, the first end of the sail shape boom slidably connected to the one articulating boom and the second end of the sail shape boom slidably connected to the other articulating boom, said sail shape boom being disposed in a longitudinal plane above the longitudinal plane of the primary boom, whereby, when the primary boom rotates through 360°, the sail shape boom also rotates through 360°, the ends of the sail shape boom avoiding contact with the mast; a sail having at least two edges, a head, a center portion and a foot, the sail being symmetrical about a vertical axis, the head of the sail being releasably attached to the top of the mast, the foot of the sail being connected to the sail shape boom, two wishbone spars being connected about the sail, a lower wishbone spar being disposed in approximately the center portion of the sail and an upper wishbone spar being disposed near the head of the sail, the wishbone spars and the edges of the sail avoiding contact with the mast, a hem formed on each edge of the sail, a respective sail line enclosed within each hem, each respective sail line being attached near the head of the sail and extending downwardly within each hem to near the foot of the sail, each respective sail line exiting from the respective hem and forming two separate support lines, each respective support line passing through a respective pulley, two pulleys being attached to the first end of the sail shape boom and two pulleys being attached to the second end of the sail shape boom, each support line being angled upwardly and inwardly over the sail and being slidably connected to the lower wishbone spar, each support line further being angled upwardly and outwardly and being connected to the upper wishbone spar, whereby the respective sail lines and support lines reduce twisting and produce even tension throughout the sail; a cam having a base mounted on the hull deck, the cam being above the midpoint of the primary boom, the primary boom rotating around the cam, a first line connected from the cam to the one articulating boom, a second line connected from the cam to the other articulating boom, whereby when the primary boom rotates in a first direction, the first line is tightened and the second line is slackened such that the one articulating boom pivots, and when the primary boom rotates in a second opposite direction, the second line is tightened and the first line is slackened such that the second articulating boom pivots, whereby the luff and leach of the sail are interchangeable when the primary boom rotates through 180°and the sailing craft passes through the wind without stalling the sailing craft by backloading the sail.
