I'm just starting to get the hang of mine after one season. I've changed points of attachment and tweaked a few other things. The other day with my wife at the helm, it seemed to fold up like a Roman window shade. She was aghast(so was I, it doesn't always go like that)! That main has been a wrestling match for years.
I've ordered new sail covers and can't wait to try them. I told the sailmaker, I want them big and loose, easy to install. If the new covers work as well as I hope, we should cut our sails up-sails down time by a half.
It might be just the thing to make your boat easier to use. Then of course, it will sell immediately.
