I want to keep my new sail in the best racing shape possible. So I'm considering buying a long sausage bag that allows me stow and car top my mast with my sail rolled up on on. I was wondering if rolling the sail up on the mast and stowing it that way would be better than taking it off the mast and flaking (folding) it all the time. Any suggestions on the best method to store and transport a sail to keep it in the best racing shape the longest.
