Mainsail
Tom -You're really only about two different things here - both ways of attaching the sail to the boom and mast. With a boltrope, you have a rope sewn into the sail that goes into the tracks on mast and boom. With slugs, they're evenly spaced slugs on the mast, usually still rope on the boom. I like slugs personally because the make the sail easier to handle, but they both work equally well.Justin - O'day Owners' Web
