A couple of terminology pointers: On a ship, the bathroom is the "head," and the kitchen is the "galley."

I like your balance of detail to clarity. It doesn't look so sparse as some deckplans, but the details don't clutter the plans. I can't really think of much else to say, other than to mention that a serif font is easier to read at small sizes and in large blocks such as your descriptive text. Also, left-aligned text is easier than centered, although for blocks this small, it's not really a big deal.

@Fuse: Trivia for you: The "wings" on Federation starships in the Star Trek universe are the warp nacelles. They are separated from the rest of the ship to insulate the crew from the harmful radiation and spatial distortion they produce.
