Having never owned a Kevlar sail, I can't provide any personal experience to the discussion. Just from scuttlebutt, my understanding has been that Kevlar sails are good for a year or two. According to Sailpower: Trim and Techniques for Cruisers by Peter Nielsen (p.27), "Sails made from (Kevlar) are very light but far from durable in a cruising context. Kevlar is brittle and does not stand up well to flogging and flexing" Further in the text he states "It's not unusual for a woven sail to last 10 years or more, while the lifespan of a laminate sail is closer to five years," but he's talking Mylar here as opposed to Kelvar.
