And is super dangerous as the conversation of iron to rust tends to consume the oxygen inside and makes the air unbreathable. This has killed a lot of people.
There is a lot of clean chains there.
It looks like every piece has additional rigging to make it easy to crane out.
There are also a lot of shackles. I wouldn't expect a ship's anchor chain to have shackles, and I wouldn't expect them to be stored with the chain.
There are also spreader plates (or multi-blocks) in there.
I would expect a chain locker to only have 1 kind of chain in it.
I'd also expect it to be less.... Tangled looking? At least a little more uniform as the chain gets put in.
This was represented as a chain locker where I appropriated it. I saw the shackles, but not knowing the first thing about maritime operations, stuck with what I read.
