North Sails 3Di™ Technology debuts in small boat one design

by North Sails on 6 Jun 2017 North Sails is proud to introduce 3Di sailmaking technology to the Melges 20 class. In the past five years, North Sails 3Di™ has received unrivaled success in grand prix markets, with around-the-world speed records and exclusive supplier status to sailing’s premier events. Adding 3Di as a standard offering to the Melges 20 class is an example of North’s commitment to providing all sailors with advanced sails for an improved on-the-water experience.

North Sails 3Di technology enables sails to be made from fiber and adhesive only—without the need for Mylar film used in string-sails. An automated tape laying system allows designers precise control over the placement and orientation of material within each sail.

“For the Melges 20 we have focused on a bespoke tape layout using North Sails 3Di RACE; Aramid/Dyneema sails developed to meet the demands of smaller boats,” said Tim Healy, President of North Sails One Design. “The result is a sail with a wider wind range, a more supple feel and a more user-friendly experience. The ability to adapt this technology for one-design classes makes our team unique and we look forward making 3Di available to more classes in 2018.”

The new Melges 20 3Di mainsail posted its first victory when Mascalzone Latino Jr. claimed the 2017 Melges 20 Scarlino Championships in May. “I was extremely happy with the 3Di RACE sail,” said Cameron Appleton, North Sails Melges 20 class leader and Mascalzone Latino Jr. tactician. “We noticed the mainsail handled a wide range of wind pressure and resulting rig tune. It was a relatively seamless transfer from our 3DL main, the sail reacted on-par with what we’d expect from 3Di RACE vs. 3DL sails.”

Consistency is a key feature of 3Di manufacturing. The technology’s reputation has earned North Sails exclusive supplier agreements to the 35th America’s Cup, Volvo Ocean Race and Extreme Sailing Series, all of which mandate identical sails under a strict one-design rule. Featuring a high level of repeatability and quality assurance, North Sails 3Di will benefit one-design sailors in the form of consistent weight, measurements and sail shape.
