Be a bit careful comparing numbers - some are "working load" and others are
"breaking strength." I think for chain and shackles "working load" is define as
25% of breaking strength. Also, you want to consider the failure mode - a quick
link can deform making it hard to take apart.

I was aware and considered working load, not breaking strength, your 4 to 1 figure is the
one usually used for chain and chain fittings.

BTW, why not use a swivel to connect to the anchor? Maybe your Danforth won't
pull out as much if it had a swivel.

Can't see how that would help.

Hope Bob checks it out, he could use the extra heave thimbles on his mooring lines.
