What are these for?

[steve yates]

I found them in the bottom of the stern locker under an old fishermans anchor. There are two u fittings ont he stern coaming, one on either side, so I am surmising they may be for attaching there and then the chain shackled to a bridle or drogue? Or simply for trailing warps, though I would have thought the aft cleats would do for that?
What do you rackon?

I don't see any reason why you would need bottle screws if they were for attaching a drogue.

Perhaps they were for holding something down onto chocks, eg spare anchor...

But why use that when a lashing would do?

 

[Refueler]

What I find interesting is the chanis are same length - but the bottle screws attach at different link positions.

Something like that would be for holding something in place ... tensioned and locked ... mmmmmm

Coarse and fine adjustment.

My boatyard used something similar to hold boat upright when ashore. A vertical post extending above deck and chain and bottlescrew fixed to chain plate

Unusual link dimensions, commonly used in the transport industry to lash whatever. They seem a bit short. The chain is not anchor chan, unless its hand deployed - there maybe another length of chain, or two - same links to which these devices attach The clue might be to find something that needs to be lashed down tightly and find the item to which the bottle screws attach. I'd look for two chain hooks or claws and in proximity a device to accept the 2 clevis pins (bolts) attached to the bottle screws. Life raft cradle (though LRs usually have some form of quick release.

Or Dan Tribe's suggestion - in which case the chain hook might be n a boat yard.

Emergency ends for a broken shroud? You might have some cable grips that could be used to form an eye in the broken end, The chain would then be coarse length adjustment, final tensioning with the bottle screw.

I think Dan tribe may be on the right track. When I bought the boat it had it’s own cradle ( which I foolishly didn’t take) and a means to tie the boat downwould make sense.

Well thats a good idea, so I’ll keep them and get some cable clamps just for this purpose!

Send a picture to the PO. Most would not mind such a simple question.

They look like old emergency steering or drogue bridles. The chain sections suggest they were meant to take shock loads and the turnbuckle style bits let you tension them. People often rig setups like that off the stern U bolts for a small drogue or warp when things get rough.


They’re not much use for everyday tying off, so that fits the idea that someone stored them away after switching to something else.

 

[thinwater]

Stored with an anchor, I would bet they were for securing the anchor in place on deck. An old school way.

Not adjustable enough to make any sense for a drogue IMO.

We’ve got a box labelled ‘I don’t know what it is but might come in handy’ full of things we’ve found on our new boat.

Put them in there.

Reminds me of the boxes in R/O's drawers / wheelhouse of ships ..... contining items like old Magnetrons etc ..... labelled : Used but Good !!

Often they were actually junk !
