A new GB/CS/1915 design

I tried a new version of my friend Cliff's GB/CS/1915 design, and it works smashingly well. The only deviations are that displacement had to be much lower and there is one inch protective deck. They are both probably improvements. The ship becomes more of a super destroyer, except one that is protected better. You may remember the photo:

The ship can make 32 knots, can cruise at 15 knots for 5,600nm, and has 4-6in QF guns and 4-21in TT with reloads. This is the Springsharp report:

 Ship tends to be wet forward

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 147.7 %
  - Above water (accommodation/working, high = better): 140.2 %
 Waterplane Area: 10,096 Square feet or 938 Square metres
 Displacement factor (Displacement / loading): 86 %
 Structure weight / hull surface area: 43 lbs/sq ft or 210 Kg/sq metre
 Hull strength (Relative):
  - Cross-sectional: 0.52
  - Longitudinal: 1.26
  - Overall: 0.57
 Hull space for machinery, storage, compartmentation is cramped
 Room for accommodation and workspaces is excellent
