ABSTRACT:
A sailboat comprising at least one mast, first and second pairs of primary half yards pivotally mounted on and vertically spaced apart along the mast for pivoting about the mast between first and second positions wherein the members of each pair extend from the same axial location along the mast to define 180.degree. and 0.degree. angles therebetween, respectively, and means for mounting a sail between the vertically spaced apart members of each pair of primary half yards, whereby the sailboat is convertible between square-rigged when the primary half yards are in the first position and fore-and-aft rigged when the primary half yards are in the second position. The sail mounting means may include a secondary half yard pivotally mounted on each primary half yard for pivoting about an axis parallel to the mast, the secondary half yards on the first and second pairs of primary half yards being opposed and vertically spaced for mounting a sail therebetween, the sail mounting secondary half yards being pivotable between a basic position wherein they extend coextensively with the primary half yards on which they are mounted and an angle position wherein the sail mounting secondary half yards form an angle greater than 0.degree. and less than 180.degree. with the primary half yards on which they are mounted, whereby the sailboat is convertible between square rigged when the secondary half yards are in the basic and the primary half yards are in the first position and fore-and-aft rigged when either the secondary half yards are in the basic and the primary half yards are in the second position or the secondary half yards are in the angle and the primary half yards are in the first position.
