The 729ft version of the F/CA/1917 (the Mod.A)

I thought I would try the 729ft version of the F/CA/1917 tonight. My goal was to be as close as possible to 180,000 SHP, and 35.5 knots took about that amount. The belt was lengthend, the beam expanded by 1ft and the draft to 23ft. The displacement grew to 18,400 tons normal. It becomes quite a potent ship (as if it wasn't, before). This is the Springsharp report:
