I just got out my 1903 Jane's All the World's Fighting Ships

I got out my copy of the 1903 Jane's All the World's Fighting Ships, so that I could try putting Colonel Cuniberti's Ideal Battleship for the British Navy into Springsharp. I was able to do better today. The main compromise is that the displacement is considerably greater than whan Colonel Cuniberti had thought would work. He specified 17,000 tons, while my design, based on his, is 21,800 tons normal displacement. This is as close as I have come to achieving his specification:
