Mine is on the cabintop
Skip--     My mainsheet is on the cabin top--it was factory rigged in that position when new.  I like it there, because it opens up more space in the cockpit.       It does make it hard for the helmsman to get to it though--you can't reach it from the wheel.  I find this to rarely be a problem, though.  If I were racing, or singlehanding, I might feel differently, but I almost always have one or more experienced guests with me whe I'm underway, so we split up cockpit tasks.Randy
