Just to add a little to that - stay-in-a-box mode is selectable on/off from the nimitz-demo file, and the limits of the box are selectable. If you want a ship which has solid decks, add it to the nimitz-demo file as another carrier, and make the path to the 3d model whatever you want it to be. You might be able to constrain the operations box enough for your needs, otherwise it's only a straight course and fixed speed atm, I'm afraid.
