I agree with JonJo on this one. It is easy to verify, by diving and watching the anchor.

As the wind becomes strong the chain lifts off the bottom and the angle to seabed is determined primarily by the scope rather than the chain weight.
As you correctly point out this decreases the holding power of the anchor. The shallower the angle to seabed the higher the holding. This is why increasing the scope improves the holding power of the anchor at 3:1 the theoretical shank angle will be 19 degrees, at 5:1 12 degrees, 10:1, 6 degrees etc. (assuming a flat sea bed)

Steep angles like 19 degrees very significantly reduce the holding power of the anchor, but to break out a well set anchor we have to lift the shank of the anchor as high as possible, by reducing the scope to close to 1:1 possible and waiting until the shank angle is very high before retrieving the anchor.

Re: Dumb Question, Chain Hook?

I share the reservation expressed by others on the strength of C links, but the good links do better in the tests than you would expect looking at them.

C-links

Jedi recommended some excellent looking G7 cable joiners that would pass through the windlass which I think are a better alternative. Hopefully he will post the link again.

We have not heard from Jedi so I looked into this. The item is a G7 chain connector from Gunnebo Johnson I bought one for 5/16 chain for $19. I do not know if it does go through the windlass but it's nice looking part but not Galvinized.

If my google search is the same I don't think those would pass through the winch.

This was the sort of thing Jedi recommended. Also Un galvanised but some cold galvanising paint will give them a reasonable life.

I bought one like you pictured from Crosby that is rated at 4,000lbs but painted. I bought another from Ace Hardware that is Galvinized but from China and rated at 3,900 lbs. They look like they might jamb up in my vertical windlass also.
