Dwarf Aircraft Carrier (WIP)

I've just started arsing about with a Dwarf aircraft carrier to launch my Gyrocopters from. I found some old frame of a railway bridge, which I had started as part of a failed drawbridge idea. It formed quite a nice angular frame which was about the right size. I didn't really have much of an idea of what I wanted except it had to have four paddle-wheels. I'm thinking the control station will be on the top of the transparent box, and the landing platforms will be on either side, with a gun at the front. Atm, it looks more like a formula one car than a Dwarf boat, though.
