ABSTRACT:
In the mainsail roll-furling system disclosed herein, the mainsail is roller-furled inside a tubular compartment in the mast itself, the sail being drawn out through an aft-facing slot in the mast. A swivel is utilized between the halyard and the luff of the mainsail and a guide is provided on the halyard side of the swivel which both positively prevents rotation of the halyard during furling of the sail and positions the upper end of the sail luff essentially in the middle of the sail storage compartment.
