Apart from Re-galvanising , What Can You Do to Prolong Chain Life ?

i,ve tried antirust paint - tedious, messy, labour intensive, doesnt last long. Anyone have any recipes they have had success with? i've thought about bitumastic but i noticed the antirust paint caused chain to slip in the winch - bitumastic might be worse 'cos its greasy...bear with me, i'm on a budget...

Before everything went Green, use to pour a tad amount of used motor oil into the chain locker... That is a big NO-NO now, so don't do it.
There is a paint that almost as good as re-galvanizing. Used it on every thing above the water line on the steel boat that I operated for the Navy. It is a two part paint.

End for end the chain on a yearly basis so that you don't end up with a chain where most of it is good and only a small part of it is bad. Some people will start with a piece that is longer than they need and cut out the rusty section if they only get rust towards one end.

Rinsing off the salt and getting it to dry out will help a lot too.

Rinse it as well as you can when you can and use something like a bristle brush to get mud and critters off.

On a calm day, lay all the chain out flaked flat on the deck. Let the anchor locker or well air out, and maybe give it a wipe down.

Be wary of using metal mixes, like galvanised chain and SS shackles. It's more an issue in the anchorage of a marina with stray current, of course, but my understanding is that it's worst in brackish water, like Florida's or the Chesapeake.

End for end is a good idea, too. Inspect for corroded or "stretched" links before their time. Consider going to a better grade if you know you're sized properly.

Use a snubber at the waterline and/or a bridle from the bow cleats/bollards. If you can cushion the shock loading of the bow yanking up the catenary, it will improve your ride at anchor and make the chain last longer.

Avoid coral.

S/V Alchemy I got a good laugh from you " AVOID CORAL" bit hard when you live on the Great Barrier Reef in Australia. Galv on the best chain I can buy only lasts 6-8 month UUUUUUG luckily we have some great guys down south who do a terrific job on regalv. I think the way to go as has been suggested is do the end for end as soon as the gal starts to go then get it regalv. Dont ever put paint on your chain to mark lengths as the Galv shop cant remove this in their pre galv dip so you will have to get the chain grit blasted and this makes the exersize to expensive. New chain is about the same price !!!! Use coloured electrical cable ties to mark your lenghts

Cheers Jacko

Make sure you have a grate in the bottom of your chain locker, so that your chain doesnt sit in water all of the time.____Grant.

I have used Z.R.C. cold galvanizing compond with good results. Comes like a spray paint or in a can by brush.

SVFINNISHLINE by the "good guys" I mean the Galv shop in Bundaberge there is only one so you can look it up wont mention names on here. Your chain will come back better that new not all stuck together like some galv shops I think they spin it after dipping. Cheers Jacko
