I have a hank-on 130% mylar genoa that I use for racing. It came with a tubular sail bag for storage. The problem is it is a real pain in the A to roll such a large sail up and then slide it into the bag. It's near impossible to do on deck or in the cabin and the gravel parking lot isn't really conducive to sail longevity. Anyone have any suggestions or tips? Is the old flake and fold into a normal rectangular sail bag better or worse for mylar sails?
