Innovative Materials for Best Results
Our racing sails have won more races than any other sailmaker in the world because we are constantly striving to make sails that are stronger, lighter, smoother, lower stretch, and faster: an unending quest for improvement. We are also continually improving our manufacturing, and materials. In the realm of competition el ámbito de la competición, the progressive approach to sailmaking has led to industry-changing innovations like the North Design Suite, 3D sailmaking, and 3Di composite sails, keeping North Sails on the frontline of records above any other manufacturer in the world.
For cruising, the durability is the top priority for any sailor; and durability is determined by much more than materials. It’s the shape that goes first, so engineering, construction, and even components all affect a sail’s usable lifespan. That’s why we maintain control of the entire manufacturing process. The quality is apparent from the moment you hoist your new sail.
3Di™ is a unique, patented sailmaking technology that produces the world’s fastest and most durable sails.
3Di sails mimic the balanced load bearing and shape holding of a rigid airfoil wing. They are composed of ultra-thin unidirectional spread filament tapes, pre-impregnated with thermoset adhesive, arranged in a complex multiple-axis array, and three-dimensionally molded into a one-piece, flexible composite membrane.
A spread filament tape is an individual yarn that has been spread out until the individual filaments lie side-by-side; forming an ultra-thin “tape.” This exclusive technology enables 3Di sails to be made from fiber and adhesive only—without the need for Mylar film.
North’s proprietary automated tape laying system allows designers precise control over the placement and orientation of material within each sail. This unitary, monolithic construction produces an airfoil that has balanced resistance to distortion in all directions. Less distortion = more speed.
