Well, no ideas from anyone yet. I have found another candidate for securing the ‘rail-rope’. It is normally used for holding soil pipes (Photo 1261).
I doubt if it will take the load if someone falls against the rail, so it may be necessary to install another taught wire just below the rope (Photo 1262), although I am hoping that one of you will come up with a better solution!
Meanwhile, Simon has not been idle. He has acquired a trailer-full of oil-based paint (Photo 1263) which, if nothing else, can be used as undercoat all over the ship!
