In general, laminated sails suffer the same maladies as Dacron sails, with one addition–delamination. All laminated sails are only as strong as the glue that holds their layers together. And while huge advances have been made in adhesives, these sails are still subject to UV degradation that can eventually cause the glue to break down. Keep a close eye out for the first signs of delamination. If the sail gets this bad, it's too far gone to save.
