  • Asymmetrical sail fabric
    Patent number: 7658160
    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,” (asymmetrical) 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.
    Type: Grant
    Filed: January 12, 2009
    Date of Patent: February 9, 2010
    Assignee: Contender U.S., Inc.
    Inventors: Duncan Skinner, Guus Bierman, Max de Bruin, Roeland Wentholt
