Analogies to 20th Century warships have been presented here. What about luxury cruise ships? Do these have the same issues? (I consider the Enterprise
to be a ship somewhere between both extremes).
Regarding the TOS Enterprise
the Making of Star Trek
said there are 16 engineering decks and according to my preliminary examinations these would match perfectly with the exterior windows and assuming an average height of 10'. However, the deck floor is noticably thicker on the center deck (or flight deck level).
, considering there is not that much space in the connecting dorsal of the TOS Enterprise
these windows would beg for explanation assuming your deck lining were accurate.
