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.

Anti-sag and load distribution means for minimizing the sag to leeward of a furling apparatus engaging the luff of a hoisted sail and for distributing the wind load on said sail uniformly along an adjacent rigging member, said furling apparatus having upper and lower pivoted connections at the head and tack of said sail and being substantially parallel to and freely spaced from an adjacent rigging member at least a distance sufficient to accomodate a furled sail wrapped around said furling apparatus, said connections defining the sole axis about which said sail rotates relative to said rigging member as the sail moves between fore-and-aft and athwartship positions, said means comprising a strip of flexible material having a width substantially equal to the spacing between said apparatus and said adjacent rigging member, and a heighth substantially equal to the length of a luff of said sail, first fastening means extending uniformly along one longitudinal edge of said strip for slideable connection with said adjacent rigging member, second fastening means extending uniformly along the opposite longitudinal edge of said strip for slideable connection with said furling apparatus when said sail is in its unfurled condition, and means on the upper end of said strip for detachable connection with halyard means for controlling the raising and lowering of said strip.
