ABSTRACT:
A sailcloth in roll good form permits efficient and cost effective construction of cross cut and vertical cut, laminate sails based on “off-angle,” (assymetrical) load bearing fibers. The sailcloth also may include a conventional warp and fill thread or fiber layout. Such sailcloth illustratively is significantly less susceptible to load force stretch, creep elongation, and airfoil shape deformation because, among other things, it is not dependent on the load bearing limitations of symmetrical, woven or knitted roll good sailcloth.
