Further redefining the boundaries of sails. Doyle's Structured Luff technology is the next generation in the world leading Cableless sails, with technology moving into jib style sails for all applications. 

Significantly less luff sag and reduced loads, creating more driving force from greater projection. Winning races all over the world. 

In the Grand Prix and Superyacht market, Doyle Sails has triggered a key change in design, delivering breakthrough technology.

The innovative approach has not only provided a new generation of high-performance sails, but started a revolution that has a far greater knock-on effect into Cruising, Racing and Multihull's. So significant are the developments, that there are many reasons that the Structured Luff technology is transforming how yachts are designed and built.

At the heart of this development is changing the manner in which load in the luff of a sail is distributed and by reducing luff sag it allows the sail to achieve more driving force.


When cruising, ease of use is paramount when it comes to sails. Structured Luff sails ensure ease of handling and ease of furling. A game changer.

How does it all work?

‘This technology came out of the free-flying Code sails we were building a few years ago where we took the cable away and put a band of carbon up the front of the sail instead,’ says Doyle’s Superyacht sail coordinator Matt Bridge. ‘As part of that and to distribute some of the straight-line load, we put a lens structure in behind and into the sail. These are continuous fibres that run from the head to the tack in the front of the sail that gives us the possibility to shape the front of the sail and distribute what used to be a straight-line load back into the sail. Now we've taken that thinking from the Cableless Code sails and applied it to our upwind designs.

In some instances, we are reducing loads by up to 50 per cent,’ explains Doyle Sails International’s COO Emma Hendy. ‘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.’
