I do a 1936 WWII era meets starship setting. Hammocks are a great touch and very much a part of our world when it comes to ship designs. You might swing by our forum and peer at some of the books if you decide to go a the retro route.
In particular the Betty starship modeled after the Mitchel bomber has some good technical drawings of all of the various parts of the ship that might lend you some ideas. =D
You do cool stuff I must say. Wish I had those skills.
