Oh, we’ll just paint a picture of the sky on the ceiling (oops, the overhead).
Surface ships have MUCH more room per sailor, and many more open spaces, passageways etc where you are not crammed person to person 24/7, compared to subs.
But that “no sky” issue is also very big. It might be tight in crew quarters on a destroyer, but you have weather decks where you can feel the hugeness of the universe and feel your spirit fly with the sea birds. Horizon to horizon views of squalls, sunsets, sunrises, starry nights, and all the phases of the moon.
It’s a great psychological morale factor that the surface sailors get, that the sub sailors don’t have at all. Subs are literally close quarters pressure cookers, where when you undress, the guy on the bottom rack is about a foot from your butt.
Yeah, let’s put twenty year old girls into that equation!
