...on the latest Harris drawing you miss something (the vertical lines) in the rails on the upper deck.
Thanks for spotting that...
...I'm wondering what the blury thing at the propeller shaft is?
Well, I'm not quite sure what to tell you here.
It was there on the reference drawing, I used for the hull. I've wondered what they were too but figured they’d be some sort of water inlet/outlet. Obviously, I've never went back to check the detail on the original sized drawing. Otherwise, I'd have noticed that it was actually the draftsman’s signature...
