Simple yet stupid, this threads for me !
Your setup is pretty much what I was looking at in the yard over the weekend Paul. One thought for you and that is that all the boats I looked at had the tackle anchored at the starboard chainplate so they didn't need to move the thing when at anchor.
It's looking very much like this is the way to go.
Thanks all for your input.
