Abstract
Abstract A sailboat in which an upwardly-extending mast is mounted upon the hull for free swinging movement about an upwardly-extending axis of rotation located aft of the mast and the boom is mounted for free pivotal movement about a pivotal axis extending transverse to both the axis of rotation and the boom intermediate the ends of the boom to allow upward and downward movement of the opposite ends of the boom, thus tending to balance the tension at the leech and the luff of the sail. In a gaff-rigged sailboat, the mast is hinged near its bottom end and the gaff is hinged to the mast near the top end of the mast so that the gaff can be folded against the mast and the mast and gaff together can be folded to a fore and aft position for ready transport of the sailboat, with minimal dismantling of the rigging.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
In a sailing boat having a hull and a sail supported by a mast extending upwardly from a bottom end to a top end and a boom extending laterally between opposite ends: first hinge means coupling the mast with the hull such that the mast is movable between a first position wherein the mast extends upwardly and a second position wherein the mast extends laterally generally parallel to the boom; a gaff; and second hinge means affixing the gaff to the mast at a location spaced upwardly from the boom, when the mast is in the first position thereof, said second hinge means permitting movement of the gaff from a first position wherein the gaff extends laterally from the mast, in the same general direction as the boom, to a second position wherein the gaff extends along the mast; the first hinge means being located upwardly relative to the boom a distance sufficient to enable the mast, the boom and the gaff to extend laterally mutually parallel to one another, with the gaff located between the mast and the boom when the mast and the gaff are in their respective second positions.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
49 words
The invention of claim 1 including: a peak halyard extending between the gaff and the mast; and means for selectively extending and retracting the peak halyard to move the gaff between the first position thereof and the second position thereof and for retaining the gaff in said second position.
Claim 4
Dependent Claim
74 words
The invention of claim 2 wherein: said mast extends downwardly beyond the first hinge means such that the bottom end thereof is located below the first hinge means when the mast is in the first position thereof; a cable is affixed to the mast at the bottom end thereof; and means are included for selectively extending and retracting the cable to move the mast between the first position thereof and the second position thereof.
