The Original Structured Luff

After eight years of developing and validating the performance benefits of its Structured Luff technology, Doyle Sails passed a significant milestone in 2019 when the concept reached the market-acceptance tipping point to become mainstream.

In the last three years, the technology has cemented its place on board some of the most high profile and high-performance Grand Prix race yachts and Superyachts around the world and delivered winning results.

"One of the unique things with Doyle Sails is that they pioneered 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."

"We had no hesitation selecting Doyle Sails for SailGP. We knew they had the expertise, technology and commitment to deliver on such a project. We also knew success would be just as important for them as it was for us. The result was that we had nothing but praise on the quality and service Doyle delivered."

"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 jib actually projects to windward instead of sagging to leeward. ‘Swept back spreaders and a dubious backstay set up that holds the top of the mast up, means that these Structured Luff headsails are a massive improvement for this yacht."
