ABSTRACT:
Disclosed is an articulating sail feeder that solves problems associated with furling and reefing sails on yachts, particularly large yachts. The inventive sail feeder includes hinge tracks arranged in articulating column that bends and rotates freely, but limits the axial twist of the sail as during furling and reefing. The inventive hinge tracks have a cross section that includes a batten end receptacle with channels for headboard cars. Hinge tracks with the inventive cross section absorb the wind-generated compressive forces exerted by the battens on the batten pockets, reducing chafing, and eliminate the need for sail slides, which would otherwise lock the sail in place during furling and reefing.
