Helix Sail Technology

LEADING EDGE DESIGN

Helix Structured Luff technology is a breakthrough sail design philosophy, using the sail structure to improve its aerodynamics and in many cases reduce the load on your equipment. Through a data-driven approach to sail design, the North Sails team uses Helix to create versatile sails that carry across a wider range.

Exclusive to North Sails, Helix Upwind utilizes 3Di composite structures in a fascinating new way to radically improve camber control. Helix Offwind reduces loads on any free-flying sail whether 3Di or Paneled, creating improved aerodynamics for a fraction of the load on your boat and mast.

LEADING EDGE DESIGN

Helix Structured Luff is a breakthrough sail design philosophy, focused on  innovating the structural elements in a sail’s leading edge. Through a data-driven approach to sail design, the North Sails team used Helix to created versatile sails that carry across a wider range.

Exclusive to North Sails, Helix pairs a structured luff with load-sharing sails to radically improve handling and control. 

Essential Facts

Helix is more than a single feature. It’s a total design philosophy that radically changes how sails are engineered.

Guided by a bespoke, data-driven process, North Sails designers engineer each sail’s structure to improve its aerodynamics.

Helix sails have become the go-to tool for improving range, while also reducing the number of sails required.

Features + Benefits

Further or faster with fewer sails. Helix sails extend your range, requiring fewer sail changes in varied conditions.

Helix Structured Luff sails enhance boat speed. Find a new gear and your power potential while reducing drag and heel.

A Helix Structured Luff activates a proactive, positive shape that responds to changes in wind flow while reducing reactive trimming.

Helix Frequently Asked Questions

Exclusive to North Sails, Helix Structured Luff is a new approach to upwind and downwind sail design with a special focus on the luff area of a sail, providing extended aerodynamic benefit, easier trimming and handling, and the potential to reduce loading on the boat and rigging.

Helix is more than a single feature. It’s a total design philosophy that radically changes how sails are engineered, built, and flown. Guided by a bespoke, data-driven process, North Sails designers engineer each sail’s structure to improve its aerodynamics.

As of January 2022, this revolutionary design philosophy comes standard on all North racing Code sails and the Helix Furling Gennaker for cruising. Furthermore, North Sails has moved to expand its range to include Helix as an upgrade for headsails.

Yes! In 2021 North Sails introduced the Helix Furling Gennaker. This new sail type was exclusively engineered for the cruising community. Helix Structured Luff transforms how sails fly and is key to building a modern cruising inventory. With a Helix Furling Gennaker, you’ll eliminate the heavy cable needed for traditional furling and experience the most reliable and easy-to-use top-down furling cruising sail in the world.
