Sometimes a Cigar is...

I have some Nautilus plans coming in the mail but I'm not one to let that stop me from art.

Here is the initial draft of the main deck of our submarine. The code for rooms (adjacent to the letters, of course) is as follows:

A = a kind of guest room
N = Nemo's quarters
S = Salon/Museum
L = Library
C = another cabin
G = Galley
B = Berthing for the crew
E = Engine room
