3Di NORDAC – Evolution to Revolution
Posted On 19/07/2018
THE DACRON CRUISING SAIL REINVENTED
3Di NORDAC transforms polyester fiber into seamless, one-piece sails that are uniquely strong, beautiful, and long-lasting. North Sails is excited to introduce this revolutionary sail technology for small to medium sized cruising boats.
For over 60 years, woven polyester sailcloth has been the default choice for cruising sails because it produced structurally durable sails at a low cost. 3Di NORDAC is a revolutionary sail technology, for small to medium sized cruising boats, which transforms polyester fiber into seamless, one-piece sails that are uniquely strong, beautiful, and long-lasting.
Woven Dacron sailcloth fails to provide value to cruising sailors because the sails lose their shape long before structural integrity is compromised.3Di NORDAC marries patented 3Di shape holding technology with the toughness and affordability of polyester sails. 3Di NORDAC sails are smoother with a more permanent aerodynamic shape for greater control, speed, and comfort when cruising.
North Sails patented 3Di process spreads yarn fibers into individual filaments, pre-impregnated with thermoset resin, and laid into ultra thin tapes. The tapes are then thermoformed on North’s 3D adjustable molds in the sail’s unique shape. 3Di sails have the properties of true composite structures, resisting strain and compressive forces in all directions.
