Doyle Sails pioneered the Structured Luff technology, changed the game and continues to lead the fleet of sailmakers trying to achieve the same result.

With many years of innovation and development in the bank, Doyle Sails continues to design and deliver sails with better performance, speed and handling efficiencies. Significantly less luff sag and reduced loads, creates more driving force from greater projection.

Exclusive to Doyle Sails, don't get left behind.

"One of the unique things with Doyle Sails is that they pioneered this Structured Luff technology, and this really is a big game changer in performance. I would say it's the biggest gain that has been made in recent times in sail development"

Mitch Booth, Superyacht Tactician, Leopard

"Dangerzone has a complete new inventory of Doyle sails with the latest design of the Structured Luff jibs. This gives the boat so much versatility across the wind range and made the boat very competitive in all conditions.  I couldn’t be happier with the way the boat performed with the sails literally straight out of the bag.  Huge credit to the team at Doyles”.

Dean Barker

"The Doyle Structured Luff headsails have changed the upwind performance of Money Penny. I call them a flying jib as when the load goes to the forestay the luff actually projects to windward instead of sagging to leeward. A massive improvement for this yacht".

Sean Langman, RP65 Money Penny

“The sails’ ability to hold their shape at all angles with virtually no luff sag is astounding on such big sails. We have reduced rig load dramatically with these sails and our performance improved in all conditions, particularly light air. Our new Doyle mainsail is exceptionally high quality and the reduction in permanent weight aloft gives immediate gains in all wind strengths". 

Jim Cooney, previous owner Supermaxi Comanche

"In some instances, we are reducing loads by up to 50 per cent. Reducing luff sag is one of the biggest factors in allowing our sails to achieve more driving force. On some of the bigger boats, we’re seeing a reduction in sag at the middle of the forestay of up to a metre, which in turn means that the sail can be projecting a metre further to windward. So there are some serious benefits for racing superyachts. But from a cruising standpoint, there are massive advantages too, where the reliability of the furl, the reduction in weight and the fact that these new sails are easier to store are all important factors in this area".

Pioneers of Structured Luff Technology |

Doyle Sails with Structured Luff technology offer more versatility and changes the way a sail behaves through a more balanced distribution of loads.

Doyle Sails Structured Luff exploits the power-potential and control previously undiscovered in conventional sail luffs.

This leading-edge design philosophy is applicable for a wide range of sail materials and boat types, exclusive to Doyle Sails.

Leading Design |

Doyle Sails Structured Luff was the largest breakthrough in sail design philosophy. It has focused on innovating the structural elements in a sail’s leading edge.

Through a data-driven approach to sail design, the Doyle Sails team have created stronger, more versatile sails that carry across a wider range.

Exclusive to Doyle Sails since 2018, we are able to pair a world leading designed Stratis sailcloth with our Structured Luff load-sharing sails to radically improve handling and control.

What is Doyle Sails Structured Luff technology? Exclusive to Doyle Sails, Structured Luff technology is a different approach to upwind and downwind sail design with a special focus on the luff area of a sail. The superior design providing extended aerodynamic benefit, easier trimming and handling, and reduction in loading on the boat and rigging.

What types of sails can I get with a Structured Luff sail? Doyle Sails Structured Luff technology is available for Mainsails, Headsails, Staysails and all others.

How do Structured Luff sails work? This begins from the design, with the load share of the sail that is usually in the luff (or headstay) of the sail being redistributed through the rest of the sail evenly. This takes load of the luff of the sail, allowing the luff to fly 'freer' and often to windward. This enables more speed from greater projection. By incorporating Structured Luff technology these sails become more stable and efficient through a wider range of conditions.

Is there are difference between a Structured Luff Racing or Cruising sail? The theory is the same. With cruising sails, the focus remains solely on reducing the weight of the sail so that it takes less people to handle, while also reducing the need to constantly adjust the sail shape. Racing Structured Luff sails allow more control over the sails luff and shape than ever before. Also lighter and faster than any other sail on the market.

Which Structured Luff Sail is right for you? Structured Luff sails are exclusive to Doyle Sails and whether you are racing or cruising, each sail is custom designed and purpose built to suit your requirements.
