ABSTRACT:
A sailing vessel is provided with an improved rig which utilizes a fabricated adapter having a downwardly depending leg rotatably held in the hull of the boat and having a first forwardly angled arm for carrying a rigid mast spar and a rearwardly angled arm carrying a rigid boom spar. The sail has a curved leading edge attachable to the mast spar and a foot attachable to the boom spar which causes the mast and boom spars to be bowed toward each other and under continuous but adjustable tension resulting in a taut sail. Since the mast spar is forward of the center of rotation of the rig. The center of effort of the sail is positioned closely adjacent, but slightly downwind of the center of rotation of the rig resulting in easier handling of the sail, greater rig efficiency and improved balance of the vessel.
