My "Super Swift" design in Springsharp 3.0b Beta

I am not particularly pleased with my Super Swift design in Springsharp 3.0b Beta. I had to accept a 35 knot speed and lower displacement, to achieve adequate seakeeping. I also had to raise the freeboard and increase the draft. The ship was supposed to be a 37 knot scout with 6-4in QF guns and 2-21in TT with reloads. I was forced to use geared turbines to remove the "revise drives" error message. This is the Springsharp report:

    - Average freeboard:  16.56 ft / 5.05 m

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 188.1 %
  - Above water (accommodation/working, high = better): 138.9 %
 Waterplane Area: 8,025 Square feet or 746 Square metres

 Hull strength (Relative):
  - Cross-sectional: 0.45
  - Longitudinal: 2.28
  - Overall: 0.53
 Hull space for machinery, storage, compartmentation is cramped
 Room for accommodation and workspaces is excellent
