Swinging mooring details

[Slocumotion]

I bring chain over the stemhead roller, then I have a short length of rope attached to make off to the foredeck centre cleat. Also shackled to the bottom ring of the buoy are two C links to attach the rope bridle (each leg of the bridle having another C link at it's outer end). Inboard ends are eye spliced for cleating off, and just take the strain off the chain.
It seemed like a good idea to be able to unhitch the bridle and keep it onboard rather than have it, and the chain and it's length of pickup rope and float (and the dinghy too) all hanging off the buoy and getting tangled up while I'm away. But now things are getting really complicated - I find I need to haul the buoy up by it's top ring and secure it while I fiddle with the C links and bridle - so, another length of rope, perhaps left hitched to the top ring by which to attach it to the pulpit. But then - that's all I'm riding to while I do the aforementioned fiddling.
Any ideas how I can streamline the arrangement?

Just a chain from buoy with a loop at the end to drop over the mooring cleat. (Pick up buoy attached to loop with a few feet of rope.)

That is what Chichester provide.

Good idea in all but sheltered locations to lash the chain to the roller.

I used to use Inglefield clips on short loops at the 'inner' end of each strop to keep all the strops together and attached to the main pickup rope. That way they all came aboard together and did not get tangled whilst left hanging off the buoy.

Photo's of these various arrangements would be helpful because I don't have the foggiest idea what C links & Inglefield clips etc are & what role they play but I do have a swinging mooring which sounds similar & could do with being simplified.
These bloody gales we keep on having are starting to cause me some anxiety.

Not a very good image I'm afraid because you can't see that both links have a split to allow them to be slid apart. The C link is the same idea done with 2 links of chain.

I'm wanting to keep the bridle arrangement on the belt and braces principle. Things can get quite lively on the mooring and I want to spare the stemhead fitting most of the thrashing and grinding it would get from the chain , but have it there as my ultimate backup. Perhaps I'm being too nervous ?

Isn't that bad practice, though? I was told to never make fast in a way that cannot be released when under load. If rope is used a knife could cut the boat free in an emergency but with chain it would probably require a hackaw which is less likely to readily to hand.

More concerned that the boat wont come adrift from the mooring when I am not there than be able to cut it free in an emergency. Cant cut it free when i am not there!

The whole idea is to interpose some flexibility into the chain to ease the snatching that you get when moored to a big buoy. The bridles provide that flexibility, but the chain remains the secure link in the mooring. Why not dump the rope bridles and interpose some flexibility into the mooring chain outside your stem-head roller? You could make a bight in the chain and have one of those anti-snatch springs - or even a length of rope. Now it's simple - just pick up the chain and make fast to your deck cleat!

Releasing under load: Vic's boat (like mine) is a 19' Sea Wych so loads are more manageable... when releasing I use the pick up buoy rope (attached to chain below the loop) to take the load off the chain loop, which is a fairly snug fit round the sampson post.

Anything a knife can cut can chafe through. I use a rope in parallel with the chain (but shorter) to reduce snatching and am amazed at the chafeing that occurs despite anti-chafe measures on the exposed mooring I have, in the weather we've been having.

ADDITION:
Also, to reduce snatching, the chain goes through an old car tyre twice, though the middle, then round the exterior and back through the middle. The idea is that snatching is damped by the loop of chain squashing the resilient walls of the tyre (others shackle two opposing loops of chains with slack in the chain in between, stretching the tyre in snatches). Also the tyre is secured about 1/3 down the chain so it lifts off the bottom in a chop, and this also helps damp things down. (I think it's the inertia of the water inside it rather than the weight of the tyre itself.)

I think you might be.It's hard to generalize because we all have different moorings,I forinstance have a swinging drying out mooring & no big buoy to pick up from & it is important to me to take the snatch out of the mooring that can be considerable when three or four tons of boat take up suddenly against an all chain mooring.I have deliberately interposed about twenty feet of nylon line to act as a damper.I would'nt want an all chain mooring under any circumstances.
What I am finding difficult is having all that line plus a small mooring buoy all floating about when I leave & then want to retrieve my mooring.
Chafe is also an issue but I hope I have resolved that for now with the modification I carried out yesterday

After our moorings got relaid by the yard a couple of years ago I found I had to shorten the chain so we didn't swing too close to our neighbour. I found that she was snatching quite hard at the chain in any sort of wavelets, so I inserted one of those rubber snubber thingies in a loop in the chain, and it has worked very well. Flexibility, but still the reassurance of an all-chain mooring. Still ok after 1.5 seasons, I don't know what their normal life is.
