[Rhodes22-list] Mary Lou's Lee helm

Thanks Steve (and everyone else) for your thoughts on our boat that wants
to go right.
Here's a summary of the problem and the possibilities offered by the group.
I'm writing this in hopes that if all the ideas are in one place someone
will say "what about.....?" and we'll say "eureka..."
We've had lee helm issues with Fretless since we got her. The learning
curve learning to sail her and the fluky wind and current conditions on the
Chesapeake have slowed us down diagnosing the problem.
She has always sailed better on starboard than on port. When we set her up
this spring we lengthened the forestay and took up the backstays. In a nice
breeze with a full main and genoa this gave us a small amount of weather
helm on starboard and less lee helm on port. It also made us really pay
attention to the difference between her behavior on port and starboard.
Roger mentioned looking at how she sits on her lines and indeed she does
have a slight list to starboard sitting in the slip (in spite of the
outboard, 7 gallons of gas and the battery all stored to port. Bill Effros
said he thought that if the boat was too heavy to port it would turn to
starboard. These two thoughts seem to contradict each other but we'll work
a bit more on her trim.
Bill & Slim mentioned heel as a contributor to weather helm but I think we
heel about the same on port and starboard. Those fluky winds make it hard
to tell.
Slim mentioned that in addition to increasing the aft rake of his mast, he
experimented with the centerboard and found he could increase weather helm
by raising the board. We may play some more with this as Stan's original
suggestion to us was to let the board drop a bit more by moving the knot in
the pennant. That doesn't, however, address the fact that she wants to turn
to starboard.
Steve mentioned sail trim in heavy air and this is an area where we really
don't know as much as we should but we've been playing with the outhaul and
the traveller and have achieved some improvements in the helm but not in
the difference between port and starboard tacks.
Jim Connolly mentioned a similar port/starboard problem but then mentioned
that he thought he had a spreader problem that might be contributing. As
near as I can tell, our mast is straight and centered. We tune the rig with
a Loos gauge and have measured with a halyard to the chainplates. We'll
take a look at the spreaders though.
Lastly, Steve and Slim mentioned that maybe something was out of whack with
the keel, the centerboard or the rudder. We'll take a look at those
possibilities. There's nothing immediately visible with the keel or the
rudder. The centerboard appears to drop cleanly and not bind or thump about
significantly but we've never taken a really good look at it. Fretless has
an unusual repair (?) to her centerboard trunk (there is a flat plate
glassed over the forward part of the trunk - between the trunk and the
centerboard cap) that prevents us from removing the centerboard in the
usual fashion).
Anybody else have any ideas?
Thanks again for helping us think about this.
