Think it's bust. Someone must have tapped it too hard.
Ouch. You don't want that in the middle of a windy week.
Whereabouts are you in the harbour?
I'm in Sweare Deep and visited yesterday, fortunately everything looked okay ..... hope it stays that way.
Abrasion certainly does play a major part in my experience. I would stick to chain and ameliorate the snatch effects by using a nylon spring to the chain for most of the length of the boat along the side deck ending at a genoa winch. That should reduce the force on your bow roller to an acceptable level.The new strops are 16mm which are around 5000kgs breaking spec. So unless abrasion plays a part then the shackles, thimble eyes or deck cleats would probably be the weakest link.
I wouldn't try a drogue personally, too much chance of the kind of thing you mention occurring. Also, I doubt it would help at all, particularly at slack tide.One suggestion to help reduce the risk of damage was to have drogue on a short rope off the stern. But my first thought was it would get tangled around the rudder and propellor at slack water or if the wind is stronger than the tide.
Itchenor Reach, the sheltered part.
I have been busy today making up a couple of 8 plait nylon strops to use as a bridle to release the load on bow roller. It appears it could have been the sideways pull on the roller fitting that bent it, when the yacht was “tacking” around the mooring. I am pondering how many kgs if energy on the 10mm mooring chain it took to bend what was a recently extra strengthened stainless steel roller fitting. The new strops are 16mm which are around 5000kgs breaking spec. So unless abrasion plays a part then the shackles, thimble eyes or deck cleats would probably be the weakest link.

Thanks Channel Sailor. I was thinking I might be safer in Itchenor Reach (and maybe I would be). But you can't be moving a boat every five minutes, last night I u the direction was more southerly which is good for Sweare Deep. For what it is worth I have a double bow roller with a single large cleat behind it. The mooring chain goes on that. I use a rope strop in parallel with the chain over the bow roller, which is then joined to an octoplait bridle above the foredeck. Like Boo2 suggests, the two arms of the bridle run down the side decks to the mid ship cleats (and then the stern cleats, mainly to store the excess, it is an old anchor warp). It was good to see the bridle stretching back and forth when I visited the boat on Monday. The chain hangs limp but ready if the octoplait fails. Obviously I regard the rope strop as an item that will wear out. I would agree the sideways pull and a lack of snubbing sound like the cause of your problem. Apologies if this is all obvious already.
Hmmm. Does sound like a possibility, and if the boat swings about more than most on the edge of the main channel that could give a complacent helm a nasty surprise. Not wishing to add to your worries but a friend had their boat clonked on Itchenor Reach on a bend on the edge of the main channel, but that can happen anywhere. It could have been an unreported bump sometime before the bad weather, (depending on how often you visit the boat.) But your first description of the pull at 45 degrees jamming and jerking rather than snubbing is just as plausible. Good luck with the bridle.There is a possibility that something hit the stem fitting (or the yacht) and bent it. It is not a particularly light weight construction fitting. Also I happened to notice some new black marks for some distance along the plastic rubbing strake and the yacht mooring is located on the side of the navigable channel to the marina.

When walking the dog at Cobnor a couple of days ago the sight of significant 'white horses' running up past Itchenor was sobering, Bosham Channel by comparison was calm.
There seem to be fewer boats on moorings this winter.
What does the “A22” mean?
