Glad you enjoyed your foray up north John! We have learned to take the odd knock, but then our old tub had 30 years of that in the hire fleet, so she's well used to it. After we painted the hull last year, I was protective for all of about a week, and then soon learned to carry some paint and a brush rather than spend the whole time terrified of some poor inexperienced helms mistakes.
I do wish some of the yards (Clive, some of Rickos have these) would get rid of the sharp metal corner castings on the aft corners where the rubbing strips should be. We had to fend of one of Rickos boats at the weekend whilst I was doing a pump out. It wasn't the helm's fault as he was doing his best mooring stern-on with limited experience and a bit of a cross wind, but those lumps of metal can't half leave a gash, rather than a black streak like the rubber would!
