Do you see any potential problems with stability given all that topwork?

Not really sure how much this thing is going to weigh. When I was building the super structure, I got a feeling that it is going to be haevy. I used thick plastic and styerne to give it some strength, but never thought about being top heavy until your post.
Today, instead of speculating, I decided to put it to test. So, I went ahead and put the model in the pool. It appreared untstable at first. Carefully placing some weight at the bottom of the hull seems to add some stability. This brings the model to its waterline mark when it is fully loaded (judging from the photos of the ship).
In short, by carefully plasing some ballast, the model appears to be resonably stable. I say this becuase I don't know if the situation is going to be any different when she sails.
Thanks for bringing this up, I would have never thought about it. Really shows how much I know about model ships!
Today, I made the rear exhausts, running hardware, rudder and propeller. I will post some pictures later, or may be tomorrow. A lot of clean up needs to be done for things to look nice in the photos
