That's terrific Geo, a real smart looking vessel. Mine won't be anything like that I fear, I'm working from memory...I saw a lighter on a tv programme a couple of nights back, that's what I'm going by. It had a small cabin at the stern, and an open hold piled high with timber, just lashed down with ropes...I think it had a winch of some sort on the bow, a few bollards, and that was basically about it. No fancy masts, although I seem to remember a couple of lights showing, and there was a big lamp illuminating the cargo hold.
I hadn't thought about putting the prop shaft in a tunnel...this was supposed to be a quick and easy build whilst I wait for some more bits to arrive for the tug.
