Abstract
A furling foil rotatably mounted on a stay of a sailing vessel carries the forward edge of the sail, and the foil is rotated to furl the sail. The foil is of composite construction and has an inner reinforcing braided layer of high tensile filaments extending helically in both directions to substantially increase the torsion resistance of the foil while allowing the foil to be bent or coiled along its length for easy transportation and storage.
