this is a follow up on one of my comments above that i would never put a dacron UV cover on a high tech sail again. The two fabrics just don't do well together ...
So the alternative is a sock. After a couple of months screwing around with this option I think we have the basics down so it doesn't seem like a hassle anymore.
I subject you guys to one more of my training videos: Zipping the Genny Sock.
