And weirdly, the steering is very precise, with no sloppiness underway, and it
happens when we're OFF the boat!
On a side note, when we leave the boat, I tie off the wheel just in case there
is more current than the wheel brake can control. This is done to keep the
wheel from turning to the stops, and to prevent wheel brake wear. Our slip is
in shallow water, and though we have never noticed the rudder touching bottom
when we sleep on the boat, the keel stub will touch during low tides.
Thankfully, we have a soft sand bottom.
Maybe the boat settles at low tide or a current comes by, pushes the rudder
against the line ties, causes slack in the chain/wire rope, causing the chain
to jump? I have not tried to look at how slack the cable becomes when I hit
the rudder stop.
The rust, however will have to be dealt with sooner rather than later...
Any further thoughts would be appreciated. Bruce Whitmore

I can pretty much assure you that there is rust. What I can't explain is why
the problem comes and goes and at such a prescribed amount. The detrimental
rust would also likely cause a looseness in the wheel and cables which would be
quite perceptible.

Per Chuck's previous comments, the radial wheel has a keyway and key, so I
don't think it can slip. Similarly, the helm wheel has a keyway and key. I've
tightened the idler pully plate bolts, but I suspect there is rust going on
under there, which will mean a full disassembly.
Sigh...

If the radial wheel was slipping on the rudder post it could cause that issue.
Maybe use a sharpie and put a line down the rudder post and onto the radial
wheel.
20º is not much movement, you may require a fine line.

Hello all,
OK, I think I have a weird thing going here...
I have adjusted the wheel to center the turks head knot straight up when the
wheel is centered.? I got it all nice & straight a few weeks ago, and came back
to the boat to find it about 20 degrees off to port.? By the way, were talking
about 20% off on the wheel, not 20% of rudder. ? After installing my autopilot,
I again adjusted it, this time getting the cables set to approximately the same
amount of adjustment on each side to the adjustment bolts through the radial
drive wheel.? This required jumping the chain 1 or 2 notches on the wheel
sprocket.
All was well for a couple weeks, and behold, on Saturday I went back only to
find the turks head knot about 20 degrees to starboard.? During these
adjustments, I have made a point to keep the cable deflection adjusted to be
relatively minimal (say 1/2" or so?), without getting so tight as to reduce the
feel of the wheel.? I've notice no issues whatsoever when we're out sailing.
During the first set of adjustments, I noticed the idler wheel bolts were a
little loose, and tightened those.?
Considering the radial wheel bolts connect to each end of the cable, and the
cables attach to the chain, I can only think the chain is somehow jumping on
the sprocket.
Thoughts?
