ABSTRACT:
Sails for sailcraft, e.g., one-design racing sailboats, are made by forming a plurality of cloth panels by cutting all edges of each panel from a bolt of cloth according to predetermined rectangular coordinates, creating marks on the panels defining fair luff, leech and foot curves, overlapping the resulting panels and securing them together. Preferably, double faced adhesive tape is used in securing the panels, the seam overlaps between panels are of constant width and the panels are tack-welded together. Sails for use with racing one-design sailcraft that cannot be altered in shape without detection can be produced.
