This technology has been refined and enhanced to make it accessible to racers and cruisers alike. Quantum led the way in structured luff or cableless technology with the successful Maxi 72 Class. More than four years ago, racing sail designers began experimenting with ways to remove the traditional torsion cable used in the luff to not only enable furling reaching sails but also to reduce headstay sag and achieve superior performance in a wider range of angles, including upwind. This shared load dictates the amount of additional structure needed in the luff. A small cable enables the sail to be easily furled and unfurled and shares some of the load on the luff as well. Simply put, additional fiber and structure are added to the luff of the sail to take the place of a traditional, large torsional cable.
