The manual says...
Actually, it seems that when I got my used boat every line on her was a bit bigger than what the manual says. Other than increased friction for lines that go through sheaves and blocks, I wonder if there's any harm in thicker lines here and there? Could weight (aloft) be that much of an issue? In light air when I ease the mainsheet I have to push the boom out with my hand. I suppose that's due to these thicker, old and fuzzy sheets? My mainsheet measures 1/2"; the manual says 3/8".The jib sheets seemed to measure 1/2". When I replaced the jib cleats with Spinlock PX PowerCleats I had to get thinner lines to fit, which was the max spec'ed for the PowerCleats which is 7/16". This happens to be what the manual says....RickM...
