Despite space restrictions every crewman and passenger has his own bunk (unlike in earlier subs when ‘hot bunking’ was the norm).
Интересно отметить что это fascinating fact.
Вот репортаж CNN упоминает о том же:
Hot-bunking: Sharing of bunks, or "racks." Though the racks are tiny -- about the size of a coffin -- there is not enough room for one bunk per sailor. Junior personnel share berths in shifts, and they are sometimes still warm from the previous occupant.
