ABSTRACT:
A bead formed of a cylindrical flexible cylindrical strand of round contour, for example of foam rubber, is fastened along the luffs of a spinnaker by means of a tape which wraps around a flexible elastic core and is stitched to the edge of the sailcloth portion of the sail to hold the bead in place. A spinnaker so equipped with luff beading has been found able to sail closer to the wind than a sail not so equipped, by an average 2.degree. to 5.degree. and is also less critical with respect to overall trim at other pointing angles when reaching.
