Sir Robin was the first person ever to perform a single handed non-stop circumnavigation of the Globe. He was knighted a Commander of the Order of the British Empire by the Queen for this achievement. For years, the sailing industry has struggled to produce a strong medium to heavy weight woven cloth solution for a Tri-Radial sail. Challenge Sailcloth invented, patented and produced the solution. Warp-Drive is made using Challenge's patented process of weaving straight warp yarns in heavy fabrics. The fill yarns take the crimp during the weaving process and encapsulate the warp yarns. Sailmakers then cut the cloth and align the strength of the warp yarn with the load direction of the sail. Warp-Drive™ Race fabrics have zero-crimp warp yarns which give the performance of a laminate with the durability of a woven.
