Network design for a ship

Does anyone have any wiring diagrams or plans for wiring a ship.

Background:
The company that I work for have just bought a ship and they're looking into different ways of networking it. So that each cabin will have a couple of network points with possible wifi in the larger public areas.

The ship has some water tight bulk heads that you're not allowed to run cable through on the lower decks, so the cables will have to be dropped down from the decks above.

So far the idea is to run 1 ring through the ship vertically.
Or
Run a ring on each deck that doesn't have water proof bulkheads but that means we'll need managed switches...

Any help or ideas are most appreciated.

Thanks,

What kind of bulkheads?  Steel?  How large a ship?  What kind of walls seperate the structures on the ship?

What about using wireless?  In that environment, it might be the better option, dpending on the makeup of the ship.

We're thinking of putting a fibre or copper back bone into the ship then running cat 5 off of it.

The loops that I described above would the backbones.

There is far too much steel to be running wifi to the cabin etc.. especially once the engines start and the ship moves.

The ship is huge, its an old car ferry that's going to be converted into a floating book fair. With network access going to different public areas for kiosks and full network access going to crew and office areas. Plus some of the ship board functionality might be run across the network as well.

Well if the ship is all steel then fiber is going to be the best bet here anyway, to reduce interference.  How many connections are we talking about?  I helped the Navy network parts of an Aircraft carrier before, and we typically used fiber for everything because of the interference from the structure.  We ran cables along pipes, between decks, and simply connected them all at a central point.  I didn't do a LOT of the work, but what I did do was complex and quite annoying.
