What???
First, that is a nice looking sail you've been offered, Jacki.
Second, you keep Dura Mater in the water so you are already far, far short on post race/sail chores. Half the fun is grinding through rolling up 3, 4 or 5 sails, repacking a couple of kites, coiling up several thousand yards of spaghetti and then hoisting the boat onto the trailer. Really, you should try it sometime. It truly adds to the experience.
And finally, if you are stuck with just one available headsail on a furler, what do you do during the race with no sail changes to contemplate, get wrong, undo, then redo, then undo again? Even the Melges 24 crowd gets to wind up and unwind the shrouds to change gears.
I bet you just sit there eating cookies and listening to music.
