Hi Dan. I removed just the bow roller fitting which I seem to remember was easy to access the bolts through the anchor well. I then welded a couple of small plates at 45 deg to the front of the fitting as I found it difficult to pull the anchor chain in when the boat was at an angle to the warp. Sadly I can't now do these little welding jobs now as I have now been fitted with a Pacemaker and the arc gives off a radiation which can interfere with it! Think it would be worth getting the fabricator to do this at the same time as it has made it much easier to pull in the anchor.
I also machined a groove in the centre of the nylon roller as I found the warp 'creaked' as it slid from one side to the other when the boat swung at anchor, as they all do!
