Ah, paying attention I see, Cob.
The rope came off the prop after the first lift to the dockside (when I noticed someone had put it there). On the second lift, just the deck bollards were used to guy off. You can see on the second pic that the stern rope isn't in the direction of the prop.
But if it had still been on in the water, I would have made the bloke who put it on, take it off
Hadn`t seen all these pics of boat finished Si...........brilliant! Give yourself a pat on the back mate. Hope it ends up a good investment. That dog is one bloody character!
