Sails of the CENTURY

When it comes to buying new sails, classic boat owners may face a bewildering choice of sailcloths and panel layouts – Nigel Sharp offers up some clarity

Not surprisingly, the priorities and preferences of classic boat owners vary enormously, not least when it comes to sails and, in particular, the material from which they are made. At the extremes are those who choose cotton for the sake of authenticity, and others who splash out on high-tech membrane sails made of exotic materials in search of racing success (although not in the Mediterranean, where the CIM rating system heavily penalises their use). But for the majority, sails made from woven polyester continue to be overwhelmingly popular, hardly surprising considering their several advantages over membrane sails: cost, longevity (at least in terms of not falling to pieces in the relatively short term, although they do lose their shape over time) and the conservation of a boat’s classic appearance.

Woven polyester sail cloth first became available in the 1950s. At that time is was generally known as Terylene, which was British company ICI’s trade name, while nowadays it is commonly referred to as Dacron, which is the equivalent product of American company du Pont.

Most sailmakers buy their cloth from four major suppliers: Contender, headquartered Holland, Challenge in the USA, Bainbridge International in the UK and Germany’s Dimension Polyant in. Between them, they manufacture around 40 woven polyester cloths, almost all in different weights, some in different colours and finished in various resins. Other makes of polyester cloth often used in sail making for classic boats include Clipper Canvas, Oceanus and Duradon.
