Our exclusive Cable-less technology is a revolutionary sailmaking application that eliminates the use of torsion cables - increasing the range in upwind and downwind angles results in more luff projection and less weight. Initially designed as a concept to redefine and test the boundaries of traditional cabled code sails, Cable-less sails have now become one of the most sought after and recognisable applications in the industry - winning all over the world and leaving competitors struggling to catch up. A similar structured luff technology is now being applied to headsails and staysails.
What is the secret to Cableless Technology?

Cableless technology sees an uninterrupted lens of unidirectional fibres designed in the luff of the sail take the load from the tack to the head. The secret behind the concept is that the load is taken along the sails natural load path instead of requiring many tons of cable tension to try and keep the luff tight. In the case of a Cableless Code Zero, the luff is pushed to windward creating a far straighter luff for a fraction of the load and allows the luff to be eased and flown for deeper angles. When it comes time to furl the sail away, the bands of unidirectional Carbon running down the luff allow for a quick and easy ‘bottom-up’ or 'top-down' furl.

The lower loads required for Cable-less sails means weight savings can be made in the mast, rigging, bowsprit and deck systems. The loads can be up to 30% less than a cabled sail, making sails lighter and easier to handle.
We're ahead of the game.

This is a product that has been under development since 2016 and has been tested at the highest level of the sport in the last year.

Given Doyle’s past experience in engineering sails that are able to save weight and handle enormous loads, Cable-less sails are a perfect extension of their resources to deliver an easy to handle, lightweight product that has application for both Grand Prix racing programs and cruisers alike.

The combination of Doyle’s experienced design and engineering team and the Stratis production process to run long, uninterrupted carbon fibres has ushered in the last groundbreaking improvement to both upwind and downwind sailing.

STRATIS Cableless Sails

STRATIS Cableless Sails are the pillar of our revolutionary technology and have been for several years. Every single STRATIS sail is 100% custom and structurally engineered for your requirements. Our STRATIS Cableless sails are no exception – our dedicated design and project management team will work through your needs to ensure that your STRATIS Cableless sail is the perfect fit for your inventory.

Known in the industry as the epitome of a high performance, lightweight, reliable downwind sail that continually solidifies its position time and time again. The STRATIS Cableless sail has quickly become one of the most sought after sails on the market, delivering results with Cruiser/Racers right through to Superyachts.

The wider industry has accepted this technology as being the way of the future, with mast makers and naval architects not disputing the definitive advantages of a STRATIS Cableless sail. We’re proud to have race boat projects where masts are being designed in line with the reduced loads derived from our Cableless technology. Every Superyacht project Doyle Sails is involved with is now using this technology to some extent, with some new build projects exploring going all in and taking it to its full extent.

Both Doyle Sails and Infiniti Yachts share a similar passion for redefining boundaries and arguably responsible for two of the biggest breakthroughs in modern performance yachting. Seahorse Sailing Magazine looks at the Infiniti 52, the first modern race yacht that will be designed, engineered and built to take full advantage of the Doyle Sails Cableless Technology.

DELTA Cableless Sails

With the success seen across the board with STRATIS Cableless sails over the last few years in both the racing and cruising markets, it was important to Doyle Sails to offer the benefits of this same technology to sailors looking for a more cost-effective option to yachts under 15m (50ft in length).

DELTA Cableless Sails are available in Doyle Sails range of high-performance Cruise Laminate cloth options to suit your sailing requirements, before being paired with the 100% STRATIS Luff Band and fitted to your yacht. The custom panel layout helps to emulate effects of what we see with a STRATIS Cableless sail with specifically designed yarn layouts. The STRATIS Luff Band attached to the leading edge houses the all-important load sharing technology to carry the load all the way from the tack to the head, dispersing this load back through the sail panels.

Using this technique we can ensure reliable furling, as well as allowing the luff to ‘fly’, while delivering a lighter, more affordable Code sail than is typically available. Our Doyle Sails experts will work through the options around Cruise Laminate cloth options, furling and hardware required to ensure you take all of the gains available with Cableless technology.

A great solution for Coastal Cruisers or Club Racers.
