Abstract: Luff furling main and head sails are subject to sagging-off to leeward in heavy winds thereby decreasing the aerodynamic efficiency of the sails. The invention diminishes or eliminates this problem by providing a strip of sail cloth which may be interposed between the luff furling apparatus and a rigging member such as a mast or stay, the strip having a sliding connection with both members along their lengths whereby the load on the sail is transferred uniformly along the length of the rigging member and the furling apparatus is prevented from sagging to leeward.
