HOW DO I KNOW IF IT’S TIME TO REPLACE MY SAILS? || Quantum Sails
Quantum Sails Annapolis’ Dave Flynn boils down years of industry knowledge into a few easy to check bullet points to help you know when to replace your sails. Here’s the quick list for reference, and read on to get the full explanation and breakdown on structural integrity versus sail shape life.
If you are experiencing any of the following issues, it may be time to consider replacing your sails:
If you can take an existing tear and extend it with your fingers.
You are having difficulty furling or rolling your sail (particularly with in-mast furling mainsails).
Your upwind performance is suffering, particularly your ability to point.
Your have excessive heel or weather helm.
You seem a little bit off the pace relative to your usual competition.

Unfortunately, no sail will last forever. They are consumables. Much like the tires on your car, your sails need to be part of your regular maintenance plan. How long a sail lasts before it needs to be retired depends on the type of sailing you are doing and how demanding you are in terms of optimum performance. In the high-end grand prix and one design world, sail life is counted in hours. This is not because the sail is falling apart, but because it is the extra boat length or two that make the difference between winning and being in the back of the pack. New sails are always faster, if only by tiny amounts. Club level racers without unlimited budgets still need to recognize that sail shape deteriorates and plan to replace the most used sails in the inventory on a regular basis. If you start with a new inventory and replace a sail, or two, a year you will be well ahead of the game. For cruising sailors, the answer is more complicated.
In cruising, the sailor should have two main considerations. The first is from a structural standpoint. How long will the sail remain intact as a triangle? The second relates to sail shape. How long will the sail function as a critical airfoil, capable of driving the boat well and being effective upwind? This question is the tougher of the two.
