Doyle Introduces Cable-less Code Zero’s

Invisible Hand Cableless SailOn the heels of delivering many of the world’s largest sails out of their revolutionary Stratis membrane technology, including the highly-loaded mainsails on Sailing Yacht A, Doyle has introduced another groundbreaking product to bring higher strength and lower weight to the racing market.   The Doyle team have launched a product known as the Cable-less Code Zero sail in which an uninterrupted lens of uni-directional fibers designed in the luff of the sail takes the load from the tack all the way to the head. This advancement will give the ability to ease the tack up effortlessly and get more luff projection for deeper angles, giving the sails constructed with this method more range, lighter weight and less total cost.  Part of this stems from eliminating the often heavy and expensive torsion ropes that have become prerequisites to successful deployment of standard Code Zero’s.

In the Cable-less Code Zero the luff is pushed to windward creating a far straighter luff for a fraction of the load; this also helps accommodate a portion of the rule required mid-girth and allowing 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.

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. The results of the yachts racing this this Cable-less technology have been impressive, including;

  • Momo, Maxi 72 – winner 2017 Maxi World Championship
  • Bella Mente, Maxi 72 – winner 2017 Carribean 600
  • Proteus, Maxi 72 – winner 2017 Corfu Challenge Cup
  • Invisible Hand, Pac 52 – winner 2017 Transpac Race

Given Doyle’s past experience in engineering sails that are able to save weight and handle enormous loads, the Cable-less Code Zero is 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 sail 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 fibers has ushered in the latest groundbreaking improvement to offwind sailing.
