Steel Yacht Anchor Chain Locker

[jim]

The anchor chain on my recently purchased steel yacht, drops into a locker made up of the bare hull plating, rust has started to appear in several places, can anybody advise of the correct treatment of the steel, and is it advisable to line the locker to avert any more trouble. and if so with what. Thanks for any advice.

The way that I found best was to remove the existing rust, bare the steel and coat with epoxy tar using chopped strand mat fibreglass as a binder to build a protective layer, which is then tough enough to take the knocks without chipping.

I would also stick some rubber matting on with the last coat of epoxy tar mix, I've seen this work very well on a couple of steel boats I've seen.

Treat rust & line with marine grade ply wood.

has the advantage, it can be removed to check the shell plating. & will take a considerable battering from the chain.

Do both.

Nothing worse than hiding rust behind epoxy tar or a less posh underseal.

You will need to clean to bare shiny metal, prime and coat with the epoxy tar . Then make a wooden liner to take the knocks but make sure that It doesn't rub through the internal coating. Steel boats have all sorts of problems not anticipated on purchase.

G’day Jim,
All the other posts to date talk about Tar Epoxy, I’m not at all sure you can still buy it; it’s been a banned product here in Australia for some years because of it’s carcinogenic content.
We had the same problem on a tug a few years back and after blasting and painting we coated it with a rubber based material to protect the paint. This material is used to line steel drinking water tanks, should not be too hard to find, we applied several coats to get a cover around quarter inch thick, lasted for years.
Hope this helps

We use a similar product in the oilfield and good it is aswell, but as you say it needs to go on bright stell, or at least rust killed steel, we use ospho, a phosphoric acid based stuff! I've got a litre on board, if you're in the meddy near me.

Re: Do both.

go all the way and remove the rust but don't line out with wood or anything that will hold moisture,,,the rubber sounds good or if you want it removeable the some kind of perforated plastic so that you never trap damp up against the steel....let it breath and it'll be good

I omitted to mention the wood lining has to be held away from the plating for ventilation etc.

many thanks for all your replies, i will clean off all the rust and try and get hold of the rubber tank treatment, sounds like the best option.
