Nice retrofit idea. I believe thats gonna work on our bow roller arrangement as opposed to drilling a new hole in the anchor. Ordered a model 15 (33#)Rocna today from our West Marine. I'm getting it for my wife's anniversary gift! (her idea)
The folks at Sun Coast Marine (Rocna dealer) verified that the 33# would be more than adequate for our 34 and thought the next size up would be overkill.
