Sew it yourself! Boston Whaler Harpoon 5.2 Main Sail Kit lets you make your own mainsail. This crosscut kit is made from 4 oz. white Dacron® using the designer's plans and features a cunningham, full top batten, lower standard battens, a boltrope on both the luff and foot, and leechline. Computer plotted with seaming and hem lines plotted right on the cloth, this sail kit can be made on a home sewing machine. All panels and patches are computer cut and ready for basting and sewing.
