It may not be a big deal, but it may need some reenforcing. You must remember this area carries all the downhaul load. I would be happy to look at your sail or answer any of your Questions. I had my own shop next to the Dairy Queen and Sail World in Avon. Hopefully this will make me easier to find and I can serve the windsurfing public even better.
Email is fine also.
Highway 12 Avon, NC 27915. To make a sail light enough to be fun, just means they tear sometimes. The clear material is called Mono-film by the Windsurfing industry. But is actually extruded polyester film. No big deal.
