Passport 40 - Mainsail Precision Sails - 500 Series Dacron

Precision Sail Loft is made from Challenge Sailcloth's Marblehead Dacron. This is one of the finest quality dacrons on the market. The yarns and fibers achieve their maximum shrinkage during processing, which means that the fibers are in their natural physical state before they are sewn into a sail and hoisted up the mast. The maximum shrinkage allows the yarns to be woven together more times per yard than any other fabric.This process is called Interlocking™. The fibers Interlock™ more times than other fabrics, resulting in a great mechanical advantage in sailcloth. The result is excellent bias stretch resistance, stability and durability.
