Proper Sail Number
I am considering entering the inaugural Lake Erie Solo Challenge sponsored by the Great Lakes Singlehanded Society this August. On the Required Equipment List put out by the GLSS it states "Proper sail number on all sails larger than a working jib". Neither my mainsail nor my Genoa have a sail number, and I'm wondering how one arrives at the "proper" sail number. The hull number of my Cape Dory 26 is #42, but I don't know whether or not that is the same thing as the sail number. Can anyone give me some advice on this?
Thanks for any assistance.
