Hello gentlemen
Mary Ann is on a swinging mooring for 7 to 8 months per year. I raise my bobstay out of the way of the mooring rope and chain because of my experience with my previous boat. The bobstay fitting at the waterline (on my Winkle Brig) snapped due to fatigue fracture. The boat in any breeze constantly swung from side to side (my CC19 does the same) this resulted in the mooring rope putting cyclical pressure on the bobstay. Consequently, the mooring rope used to wear appreciably at the point of contact requiring annual replacement. However the real problem was the constant on-off lateral load on the bobstay which caused the fitting (a stainless steel eyebolt) to fatigue fracture.
You can see my solution in the album "Mary Ann Modifications". Before I used chain for the bobstay, I had the standard SS wire. I then connected the Dyneema lifting cord (halyard?) to the bobstay with a 25mm SeaSure block, the block was free to run along the bobstay and find it's own position.
I use the starboard fairlead for the mooring rope which is the opposite side to the (raised) bobstay. Also I have a rubber anti-shock device fitted to the mooring rope, this is positioned so that as the boat swings (to starboard), it is the rubber shock stopper which makes contact with the stem and not the mooring rope. This prevents any damage to either the GRP stem or the mooring rope.
Northumbria Water who own Kielder Water also insist on a secondary mooring chain which will restrain the boat in the event of the main mooring rope failing. I bring this onto the foredeck in the gap between the bow-roller and the stem. The 6mm chain is inside clear plastic tube to brevent any damage to the boat.This chain is attached to a 10mm eyenut fitted to the bowsprit pivot bolt via a snapshackle.
This arrangement makes it very easy to attach and detach the mooring rope and secondary chain from the foredeck.
I hope this description is of some use.
