Mooring Problems

[Wilfred27]

I sail a twin lift keel Freedom 21 at the Ullswater Yacht Club in the Lake District and I have a problem with my mooring set-up. I have an 18mm dia nylon mooring strop attaching the boat to my mooring buoy with a back-up chain connecting the buoy to the bow eye on the boat - see sketch. The back-up chain is not carrying any load. However I find that the chain ends up wound around the top eye on the buoy and the nylon mooring strop is seriously “unwound” against the lay of the rope close to the buoy eye! I have checked that my mooring buoy is free to rotate and it is.
Pls can anyone advise what is going on here - clearly I’m making a serious mistake somewhere? Should I replace this setup with two equal length nylon mooring strops and remove the chain “back up”. All advice welcome.

If that's a hippo type buoy then why is the swivel underwater and not on top ? The swivel will last so much longer so less chance of your strop unwinding.
Two strops nearly always end up wrapped around each other , sometimes so tight they need cutting off. Use either a chain or strop, not both.
It may be that the boat rotates pulling on the centre eye of the buoy and it is not rotating.
Rotating by hand is probably under a very low load. When it's strong winds it may not rotate

Forget nylon. Use swivel at bottom of buoy and rely on the chain at swivel. Pick-up buoy attached to chain. If you want snatch take up; stick a rubber snubber on chain.
Ps chain should start under bouy at swivel.

Try putting another swivel at the top of the buoy and connecting both chain and strop to that.

The one under the buoy isn't working for whatever reason.
