Springsharp just can't handle certain ships well

I tried to see if I could get a good Springsharp design for a 1914 updated version of the Ger/CS/1905. I wanted pretty much the same dimensions and 37 knots. I also wanted a larger patch of 2in armor. As usual, there is an abnormal draft, as that is what is needed to get adequate strength in Springsharp, even for a small vessel. I would be interested to see what I could do with my program. I have done calculations for British destroyer-type vessels of about 1914, and if you do the hull weight calculation, the numbers are typically something like 3.0 or 3.1 x 10^-3. The equation for this is:

Hull weight = Factor x 10-^3 x length x beam x hull depth

This is my Springsharp report for what I would consider a failed design, although it sort of "works":
