From the Quantum Sails website:
"As a triangle, sails will last for a surprisingly long time. It is not uncommon to find sails still in use that are 10-15 years old. Structurally, they gradually lose their integrity over time, principally as the materials and stitching fail under the influence of the sun. UV causes woven polyester materials (referred to generically by the trade name Dacron) to gradually lose tear strength. If you can take an existing tear and easily extend it by pulling with moderate pressure, itís over. You can fix the tear with a patch, but it will just keep on tearing in other places, often at the edge of any repair. Likewise, if you can run your fingernail across the stitching and pick it off easily, the sail needs re-stitching. It is normal for the stitching to rot before the material in the sail, so it can be re-stitched, and should be periodically during its lifetime."
