[Public-List] stern tube rudder post corrosion problem

[Mike Lehman]

Many of the older boats have delminated cockpit soles, because the tube goes all the way to the underside of the cockpit.

> We have A30 #319. I have been looking from the companionway back over our A4 at the rudder post for a couple of years now. Although #319 is a pre-liner boat, I seem to see a stuffing box on the rudder tube. I have assumed that our A30 might be exceptional (aren't they all?) because just above what appears to be a stuffing box is a chain sprocket on the rudder post which is coupled via a chain to a very old auto pilot located in the starboard cockpit locker. Fortunately the engage/disengage lever on the old auto pilot works very well and when disengaged, the tiller is quite free to move. I have pictures of the set up -- if anyone would like to see a few of them, drop me a line and I will send them along.

In light of my interest in keeping friction in the rudder to a minimum in order to facilitate self-steering (sheet-to-tiller and/or wind vane), this seems like a small price to pay.
