Sailmakers generally refer to the life of a sail in hours or seasons, rather than years. The lifespan is affected by the amount of time sailing and the level of care given to the sails. In the mid-Atlantic region, the main sailing season can begin in early spring and extend late into the fall. A sailing season in the upper Midwest, for example, is much shorter, thus extending the life of a sail. The lifespan of sails that spend the sailing season furled on your headstay, in your mast or boom, or left on the boat to endure the frigid months of winter, will be much shorter than the life of sails that are properly protected or stowed.
