Never store a wet sail for a prolonged period. Never leave sails in a hot car as the associated temperature extremes may cause shrinkage, distortion, and possible fabric delamination. Monofilm Care Monofilm sails are made of polyester film and require special attention. Handle film sails carefully to prevent scratching or creasing. Monofilm is extremely strong but tears easily when punctured or slashed.
Small tears require immediate attention and can be temporarily repaired with mylar tape or decals.
Roll them compactly and secure with a sail tie during storage or transport. Sunlight Damage Avoid subjecting your equipment to prolonged and unnecessary exposure to sunlight. The absorption of excessive amounts of UV radiation will shorten the service-life of any sailboard sail. UV degradation is highly dependent upon temperature and can be severe in tropical environments. Sails should be stored in a cool, dark area.
