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, resulting in more luff projection and less weight. Initially designed as a concept to redeﬁne and test the boundaries of traditional cabled Code sails, Doyle Cableless 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.
The Cableless technology sees an uninterrupted lens of unidirectional ﬁbres designed in the luﬀ of the sail takes the load from the tack all the way 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 Cableless Code 0 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 allows for a quick and easy ‘bottom up’ furl.
The lower loads required for cable-less sails means weight savings can be made in mast, rigging, bowsprit and deck systems. The loads can be up to 30% less than a cabled sail making sails lighter, easier to handle and set up with a straight luff.
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, the Cableless sails are a perfect extension of their resources to deliver an easy to handle, light weight product that has application for both grand-prix racing programs and cruisers alike where a versatile sails with a wide range will enable more time spent sailing.
The combination of Doyle’s extensive design and engineering team with the unique ability in the Stratis production process to run long, uninterrupted carbon ﬁbres has ushered in the last ground breaking improvement to both upwind and downwind sailing.
