News Doyle Sails launches innovative new Stratis ICE fibre

12 Aug 2013

Doyle Sails is proud to announce the official launch of Stratis ICE, available exclusively throughout the Doyle global network of lofts. Part of Doyle’s Stratis sail range, ICE is a game-changing product that offers weight savings, performance gains and high durability levels for both cruising and performance sails.

ICE is an entirely new and unique UHMWPE (Ultra High Molecular Weight Polyethelene) fibre, developed by the Doyle Stratis team following market demand for a creep free and highly durable sail membrane. Exclusively licenced to Doyle for marine use it exhibits similar properties to high modulus carbon, and is a derivative of Spectra.

Since its development, ICE has undergone beta testing on more than 100 yachts – including Team Korea, Hugo Boss, Secret Men’s Business, Sanya, Orbit and Wally 107 Kenora ¬¬– with outstanding results.

What are the benefits of ICE?

Low Creep:

ICE has the highest creep resistance of all UHMWPE sails: half that of a Dyneema SK78 product


Lightest sail for given strength when blended with carbon

Specific gravity of just 0.97, almost half of carbon fibre’s 1.8

Easy to handle

High Strength:

ICE’s initial strength is comparable to higher strength para-aramids. However, real benefits are shown after repeated flex, where ICE hardly loses any strength in comparison to others like carbon, Kevlar and Twaron which fail.

High Modulus:

ICE has a modulus comparable to standard modulus carbon fibre. On a weight-for-weight basis, is higher than almost all other UHMWPE and aramid fibres. It will retain that modulus even after extended mechanical fatigue.

Low Crimp:

Due to the fibre construction and unique manufacturing process of Stratis, ICE fibre is laid with zero crimp, meaning that the “apparent modulus” of the fibre is 10 to 15 per cent higher than standard modulus carbon.
