Wow that is not the sail I have. I bought a 3DL "Marathon". It is a white dacron sail with the 3DL sail sandwitched inbetween. I cannot beleive you rep speced that sail for a furler! That sail should not be on a furler.
My last marathon was on the boat from 8 years and look like that after 8 years. I was told that was a Pentex Delam problem. I put 1000+ miles a year on Madcap and the Marathon is the way to go. Very durable, great shape, but a little heavier than your sail. I hope to get anouther 8-10 years on my new sail.
I dont have a UV cover to keep weight down. I take it off and flake it or run a sock up if I am going to sail the next day.
