Abstract: A wind-propelled sailboat having a main hull and an outboard pontoon, a mast mounted upon the hull and a triangularly-shaped sail removably connected and secured at its peak to the top of the mast, the sail being controlled for propulsion of the boat by manually manipulated lines connected to each lower end of the sail, and manually controlled rudder means for steering of the boat. The sail is preferably not provided with a boom but is free for shifting either luff of the sail as a leading edge by means of the lines connected to the two lower ends of the sail. The sail-connected lines or sheets are each passed through swiveling blocks and locking cleats arranged for selectively drawing and releasably engaging the lines to draw the sail luffs taut.

Abstract: A wind-propelled sailboat having a main hull and an outboard pontoon or outrigger, a mast mounted upon the main hull and a sail removably connected to the top of the mast, the sail being controlled for propulsion of the boat by a manually manipulated lever sheet-connected to the sail, and manually controlled rudder means for primary steering of the boat.
