Any practical way to extend anchor chain?

Is there anyway to add a length of anchor chain to what you already have without compromising the G4 existing chain strength rating?

I'm interested in this too. This has come up here before and if I remember correctly there is no good way to do it.

Do you have all chain or chain and line as your setup?

Depending on the chain you intend to use you could try a swivel (like connects the chain to the anchor), a double clevis, or a lap link.

Well you could open the end link on the old chain, pass it through the first link of the new chain and then weld it closed again. After that hot dip galvanize the area around the weld. Any decent welder can do this for you.

I went through a similar search in the spring. Many suggestions included having a link welded but I was never quite comfortable with that.
I ended up finding a 1/16" larger stainless quicklink that had a working rating higher than the G4, and a breaking rating far beyond the G4.

The main concern noted by others about stainless quicklinks is them jamming the windlass. It is a little bigger than the G4 links but runs through my windlass (a mcmurry) without jamming. YMMV.

50+ nights on the hook and no issues so far!

Watch the galvanizing on the chain links to each side of the SS link.

I had two 200' lengths of chain that needed to be regalvanized and had 50' at one end that was pitted, so removed. Had a welder cut a good link open, remove the galvanize around the weld, add the other chain, and TIG weld it. Then the weld was dressed so it matched the other links and the whole chain was regalvanized.

If you have your chain joined by welding, it must be done by a professional welder with a TIG machine to ensure no impurities in the weld. While intellectually I know this is now the weakest link in the chain (G4 3/8"), with a 5, 400 lbs working limit and 16, 200 lbs tensile strength, I'm sure something else is going to let go before that link parts.

If you only have 90' of chain, forget welding and regalvanizing. The cost will exceed the price of replacing that 90' in a new length of chain.

Buy new chain at the size/length you want.

Sell old chain.

A riveted lap link will have half of the working load as the base chain if the base is G4 chain. The wll of a 5/16 lap link is 1,950 lbs and the wll of 5/16" G4 is 3,900 lbs. See SEAFIT Connecting Links | West Marine.

And I wouldn't weld a link without x-raying the weld.

So the answer is no. Buy new chain of the right length.

I once had same problem and came up with an answer. I linked the two pieces of chain with 6 feet of appropriate three stand nylon using the standard rode to chain splice. This worked fine for many years just had to watch the splice as it went through the gypsy. The wear on splice same as any chain to rode situation.

Eyeshulman,
Nice to see you back. I like your style.
And a nice very inexpensive solution to the problem.

Many here have been leary of line splices (including me) but quit a few highly regarded menbers have posted time tested experiences.

I believe the riveted lap link David posted above is stronger than the rode to chain splice. I have used the link for several years without a problem but had to redo the splice in that time. I do keep an eye on the link throughout the year. It's at one of my 30 ft rode marker increments so it's marked with zip ties and is easy to find.

It still seems like plenty of chain unless he's in some pretty deep water.

Just used the seafit link to joint to 50ft 5/16 galvanized BBB chain together, same working load as the chain, The owner at England marine here in Crescent City told me the commercial guys use it all the time and is just as strong as the chain. Here are some Photo's , I'm going to try it, I will keep a close eye on it and will see.
