The ability of a sail to resist stretch and maintain an aerofoil shape is directly proportional to the strength and stretch resistance of the materials used. Compared to woven polyester sails, Quantum’s Fusion M™ membrane sails provide significantly better shape when new, and two to three times the shape life. The result is a sail that is easier to trim, provides better helm and heel control, superior reefing, points higher, and is faster on every point of sail. That means more fun sailing!
