Main sail lashes/cords/bungee/gaskets
I have a FS which I keep on a small lake. I moor the boat, and cover it with a cockpit cover when not in use. Taking the mainsail off each time is a bother, and I would prefer to leave the mainsail on the boom and use sail cords/lashes/bungees to keep it ship-shape between uses. In shopping for sail cords, there are a few standard size bungees - 12", 16" and 24" inches. Anyone have a recommendation on which are the right size to keep my mainsail neat? Thanks. Gary p.s. There seems to be no standard name for these things - lashes, gaskets, bungees, cords, etc. And yes, I know, I could simply use a short piece of line or the main sheet. But I am looking for a simple and quick solution.
