I actually was in the middle of a compile when I posted the .map, although the posted .map file has much more stuff than the one I compiled.
I got it to compile fine, just had no lights so navigating the ship was, um, impossible.
At its current state I get around 1000 r_speeds with vast viz or whatever it is.
Like Jitspoe said, it will take a butt load of custom textures to make right.
I'm currently doing crazy interviews looking for a new job (12 years here is good enough).
If I do find a new job soon my map making days may be all but over, as I do most of my work here at work, and my home BSP suffers from that screen goes blue bug when I move around.
I think, if I make sure the internals are as isolated as I can get them from the outside water area, the r_speeds won't be so bad.
There is almost no need to go outside, besides getting to the BlackHawk...which, btw, I though about, and may make it hovering above the deck with a rope ladder hanging down. We'll see.
