I made a failed attempt to implement Colonel Cuniberti's Ideal Battleship in Springsharp

I'm sorry to say that my attempt to implement Colonel Cuniberti's Ideal Battleship for the British Navy did not work so well in Springsharp. I cheated and modified the specifications until the design "worked" to my idea of what such a ship would be. What I ended up with was a "Battleship-Cruiser" along the lines proposed by William Hovgaard. The main shortcoming is that the belt is too thin (9in). I recklessly increased dimensions, as 521.5ft x 82ft x 28ft was too small for ship that could make 24 knots and had 12-12in guns. This is the Springsharp report:
