<P> In most modern warships, the commanding officer has a main cabin--the in - port cabin, often adjacent to the ship's central control room (operations room)--and a sea cabin adjacent to the bridge . Thus, when likely to be called from sleep or attending to administration, the CO can go to the sea cabin and thereby be able to appear at the Bridge or Ops room immediately . The sea cabin is sparsely equipped, containing just a bunk, a desk, and basic toilet facilities . The in - port cabin is more lavishly furnished, with separate bedroom and combination sitting room / office, and more elaborate toiletry facilities . </P> <P> For ships intended to act as flagships, like the aircraft carrier USS Lexington, the admiral also has a sea cabin (adjacent to the captain's sea cabin) and an in - port cabin, in addition to the captain's cabins . Admiral Fletcher's sea cabin in the USS Yorktown in World War II had a bed, an easy chair, a table, and a shower . </P> <P> Officers will normally have their own cabins, which double as their offices . Some senior petty officers may have cabins for similar reasons . </P> <P> Sailors sleep in berth areas . </P>
