Mary Lou,
I think Bill's on to something here. The more the boat heels, the greater
the weather helm. So maybe you're heeling more on a starboard tack. Do you
have an inclinometer so you can tell exactly how much heel you have? If
not, can you jury-rig some kind of little plumb bob--maybe a modified
gimbled drink holder would do.
In lighter air, when your 175% is all the way out, do you still have the lee
helm on port but not starboard? I'm probably reaching here, but wondering
if, when the jib is reefed in, the roll of reefed sail cloth at the luff has
any effect. It seems that this would be negligible if at all. Just asking.
