Reworking the forward section of the Nautilus, I added a forward hatch just behind the wheelhouse, I was never happy with the cut I made through the upper section of the Salon.
With the cut gone and only having one entrance, finding Nemo would descend the steps turning aft and travelling back through a short corridor and the a stairwell, heading down to the main deck (2) (there are 3 levels) then turning forward walking through the dining room, library, salon and right hatch through the corridor to the next stairwell to the wheelhouse.
So I decided to add a second one
I am also thinking of adding oblong windows to the Salon removing the current setup.
Its fun but time consuming working out these details..
