Leaking Rudder Post fitting Farr 38

I have attached photo of the rudder post on my Farr 38ft (11.6m). This construction is apparently a reinforced fibreglass through hull apparture with a bronze ring attached at the top to the stainless shaft of the rudder. Recently we were aground overnight at low tide and the stern rested on the rudder to some extent although the sandy bottom was soft. This setup now leaks (say 100-200ml/hr) but only when underway not when moored and the rudder shaft slops around inside the post more than it did.

I do not understand how the watertight seal is achieved with this design and what must be done to remedy the leak and play in the rudder shaft that has resulted. I would be grateful for any advice from anyone familiar with this setup.

Thank you

Peter Mc

Re: Leaking Rudder Post fitting Farr 38

Hi Peter, there must be a seal of some sort under that metal ring. The rudder bearings have been damaged. No option but to pull the rudder and have a look inside the tube. I've not done a Farr 38, but I'm sure it's not hard!
If you posted this message on Articles - The home of New Zealand sailing - Crew you are likely to get a more knowledgeable response - lots of Farr 38s in NZ!
Cheers
Matt

Thanks Matt
Unfortunately the steering cable aluminium disk has chemically "welded" itself to the SS rudder shaft over the last 30 years also the rudder shaft is longer than the distance to the ground on slip not sure I agree it would be easy. Thank you so much for reply, Cheers

Re: Leaking Rudder Post fitting Farr 38

If t he yard will allow it, digging a pit under the blade can help in getting it out... kinda hard if it is a paved yard!

But I agree... it will need to come out somehow if you want to get to the bottom of the issue.

Re: Leaking Rudder Post fitting Farr 38

Thanks Jim
As you can see from attached photo the cradle is steel and the slipyard is concreted. Many thanks for your effort to reply. I still would like to have an opinion from another Farr 38 owner who might have tackled this so I know what I am up against. Cheers

Re: Leaking Rudder Post fitting Farr 38

You've still got to get it out. Unbolt the quadrant, get some real penetrating oil, leave that on the alloy/stainless joint for a couple of days. Is it a fully circular quadrant? If so, it's keyed to the stock as well. Hammer if needed, it's got to come off. New quadrant if you have to. Once it's loose, get the travel lift back and lift the boat high enough, drop the rudder, and get on with the repair... :-)

Re: Leaking Rudder Post fitting Farr 38

Were you experiencing a lot of motion while you were resting on your blade???

Seems hard to believe that the actual bearings were damaged if not... Although the "mounting" for these/this could have shifted... Really hard not to know what the heck is going on without pulling as recommended...

Alternatively... maybe you just have packing under that ring, and the lateral forces compressed it (the packing) and opened it up... Quite possible that you have always had slightly worn bearings and the packing was taking up the slop...

Get that ring off and have a first peek... You may get lucky and limp along with a repacking ???

Re: Leaking Rudder Post fitting Farr 38

Possibly a lip seal somewhere, and the bashing upset it in the slight groove that will have worn in the shaft.

You might be able to lower the rudder enough to inspect the shaft and replace the seal without dropping it out completely.

Lots of Heat is your friend as far as removing the quadrant. Normally they are in two halfs that unbolt?

Hopefully a farr38 owner can give you proper details of whats in there. Good luck! I pulled my rudder last year, it was an awkward job.
