Following discussion. When those of you who use a chain hook say “chain hook”, is this some kind of special marine application anchoring device or the same kind of tension secured hook you would find on a log chain? Thanks!

If I anchor real shallow and only have chain out, I use the right size chain hook. Attach the anchor hook to 4 or 5ft of rode, hook on to the chain and fasten the rode to the bow cleat. Let out a tad more chain to take the strain off the windlass and you are done. Some boaters use 2 chain hooks and snubbers and tie off to the Pt & Stbd cleats. When the anchor is stowed while underway I attach the chain hook again. Just another precaution in case the anchor deploys by mistake.

Anchoring seems easier to me if I am not useing all chain.

Martin.

Not sure if this will work but I will try and post a pix from google. There are both marine and standard (logging) versions of chain hooks.

Chain or Grab hook
Hook has a slot to let the chain link in only on the narrow dimension.

versus a slip hook
Hook is open and will allow chain to slide through in any orientation.

There are several types of "Chain hooks" used boats: The industrial ones shown by Harvey are not really applicable.

The rope is secured with an eye splice directly, or a shackle (Shackles for bridle) thru the ring of the chain hook. You let a loop of "lazy chain" hang between the boat and chain hook.




This is a Devil's claw:



A more secure version:





Finally what I like, is a SS plate with two holes and a slot. Each of two snubbers is placed on each side using a shackle thru an thimbled eye splice. This is a locking version, but I would never use a carabiner. :

Another bridle / chain attachment solution is with the use of dyneema soft shackles. I have two 3-strand nylon lines in to which I spliced a thimble. I run a dyneema soft shackle through each thimble and then through a link in my anchor chain. Each 3-strand nylon line gets secured to my two bow cleats.

I use this:

The 6mm fits through the links on my ACCO G43 5/16 chain and has a breaking strength of twice the max working load of the high test chain. They have the added benefit of not accidentally falling off like some chain hooks can until they're loaded.

I don’t know if this is directly relevant to this discussion but I went all chain a couple years ago and now I am going back to rope and chain

The reason is because of something a person may not think of at first-

When we are anchored, the chain slowly drags on ocean floor as the boat moves with current and wind. That sounds travels up the chain to right above our heads when we sleep in the bunk.

I have also thought of wrapping the chain on foredeck as a sound dampener.
Not sure.
Just something to think about. Never had that issue with rope and chain

Do you use a snubber? We have had chain noise transmitted the the water on hard seabeds.

I've never seen one of these. Any idea of a source?

Thanks

I suspect that is custom made. Not that difficult for any good machine shop to make. If you have a source of SS and a decent shop, it can be DIY. I made several similar when I lived in Long Beach CA--and had a dealer who had a lot of scrap 1/4" SS material cheap.

"SEADOG Chain Gripper Plate SS" is commercially available. However the slot cut is too wide for our 1/4" chain (it is made for 5/16 to 1/2" chain.

Basically a flat plate: their's is bigger than needed at 5/16" thick and 3" x 4", for our 1/4" chain, 2" x 3" with 1/4" thick will suffice.

Bob, I have been using the one on the third picture of your post ("A more secure version") on my 1/4" chain with very good results, I think i got it from Defender.

Yes, the Suncor Anchor Snubber Hook, is available for 1/4" chain and is about $22. It could also be used with two snubbing lines, if you have a bow shackle, and a SS thimble in the throat of the splice of each line.

Yes, that is the exact set up i have, works very well, never had the hook slip off the chain even in the La Paz anchorage where opposing wind and tides can lay havoc with your tackle. Your chain might still wrap around your anchor though if you stay there long enough,
