Jim said this: "He had just bought the boat. It sank the next day, despite him having had a survey, the rudder stock tube gave out. The insurers are still arguing, presumably with the surveyor and his weasel clauses." Naughtyfox said this: "We've had a new stock fitted 2 years ago, when we had a top bearing put on (didn't seem to have one of those at all!). I have wondered about painting that tube - shouldn't it also be 'blacked' inside? But.... how?" Jim replied: "seal around bottom of hole and shaft with blue tack. Fill tube from top with blacking. Drain, dry, repeat." Has anyone here painted the inside of this tube? I'm wondering if we should, this June, when our boat is out of the water. I don't understand how the boat above sank - our tube goes straight through the diesel tank, and I can't see our boat sinking if the tube rusted through (how thick are they?) as liquid is supposed to be in the tank anyway - I'd imagine we'd see diesel seeping out and leaving a trail behind us. stock photo (haha! geddit??!!)

You mean you haven't painted in side the tube? My god foxy, you need to do it immediately, before you go cruising again. Your boat is in imminent danger of sinking.

The last two hull surveyors said nothing about it.* I would like to know about it, though.
*why not, he wonders.

Elum tube is the term. Does it go through the diesel tank on your boat?
usually it does but not always.
Eta if it doesn't go through the tank with the tank(s) in a different location then the bit where it goes through the uxter plate (inside the boat behind the weedhatch) can be a nasty moisture trap and result in corrosion and failure of the weld holding elum tube to the uxter plate (top of the swim). This is below water line in almost every case unless boat is unballasted or an unloaded workboat so failure would lead to a flooded engine bay and possibly sinking depending on bulkheads.
If it does go through the tank then at least some of the elum tube arrangement is going to be protected from corrosion by the fact it has oil around it.

With tiller removed.

Elum tube is the term. Does it go through the diesel tank on your boat? Yes. I do not believe that diesel 'on the other side' will help to prevent the 'water side' from rusting.

I think this is an interesting line of inquiry. It's not often people ask us if we have painted the inside of our tiller stock tube.

It's not often people ask us if we have painted the inside of our tiller stock tube. Rudder stock. The tiller is what you clutch on to with a vice like grip while the one lung wonder throbs away for all it's worth beneath your feet. An Ellum is an archaic term relating to old butty boats.

It's not often people ask us if we have painted the inside of our tiller stock tube. It's not worth trying to paint the inside of that rudder stock tube because you won't be able to clean up and prepare the surface properly, so whatever paint you do manage to get on it will only be covering over rust and/or scale, and corrosion will continue behind the paint for the few weeks before it falls off anyway. I don't know how old your boat is, but if that tube is the original and the boat is around 20 years or more old, then it will almost certainly be getting very thin and close to failure in way of the normal waterline. It's not a maintainable part of the hull structure, . . . replacement of the tube or a new freestanding fuel tank are the only practical options you have.

Yes, but should the rudder stock tube be painted (bitumened) inside? So far, no-one here on TB has answered whether they've done theirs or not. They are all thinking they should have done it... and... like us.. worried that soon they will be leaving a trail of diesel all down the Trent & Mersey / southern Oxford. I wish I could go back in time 33 years and see our boat being built.

Elum tube is the term used for motor narrow boats Horse drawn and butty boats had the rudders mounted outboard so this tube did not exist. It does exist on steel motor narrow boats and is called the elum tube.

I don't know how old your boat is 1986 - 33 years. Although a hull survey report has it as 1989 (- I think someone lied). Built by Delph Marine - now gone. I have a list of Delph Marine boats, but have never spotted one, and have never ever seen a boat like ours. We still like the design and layout, but there are still many mysteries for us to fathom.

If your boat is 33 years old and that tube is the original, then it's already well into the 'borrowed time' phase of it's reasonable life expectancy.
