In 2004, I wrote about a small cruiser for use as a destroyer flagship. I tried a design in Springsharp 3.01b1 and have an acceptable design. I may want to work at improving it, but I was able to achieve something viable. I don't have it fully developed, with an AA armament. The ship has 9-5.1in DP guns. This is the Springsharp report:

    - Armour Deck: 231 tons, 7.1 %
    - Conning Tower: 19 tons, 0.6 %
 Machinery: 1,004 tons, 31.0 %
 Hull, fittings & equipment: 1,258 tons, 38.8 %

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   2,616 lbs / 1,187 Kg = 39.4 x 5.1 " / 130 mm shells or 0.7 torpedoes
 Stability (Unstable if below 1.00): 1.19
 Metacentric height 2.0 ft / 0.6 m
 Roll period: 13.1 seconds
 Steadiness - As gun platform (Average = 50 %): 52 %
   - Recoil effect (Restricted arc if above 1.00): 0.47
 Seaboat quality  (Average = 1.00): 1.05

Hull form characteristics:
 Hull has a flush deck,
   a normal bow and large transom stern
 Block coefficient (normal/deep): 0.420 / 0.429
 Length to Beam Ratio: 9.98 : 1
 'Natural speed' for length: 24.17 kts
 Power going to wave formation at top speed: 59 %
 Trim (Max stability = 0, Max steadiness = 100): 50
 Bow angle (Positive = bow angles forward): 9.00 degrees
 Stern overhang: 2.00 ft / 0.61 m
 Freeboard (% = length of deck as a percentage of waterline length):
    Fore end,  Aft end

    - Quarter deck: 15.00 %,  13.00 ft / 3.96 m,  12.00 ft / 3.66 m
    - Average freeboard:  15.65 ft / 4.77 m
 Ship tends to be wet forward

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 119.3 %
  - Above water (accommodation/working, high = better): 168.6 %
 Waterplane Area: 12,502 Square feet or 1,161 Square metres
 Displacement factor (Displacement / loading): 102 %
 Structure weight / hull surface area: 62 lbs/sq ft or 301 Kg/sq metre
 Hull strength (Relative):
  - Cross-sectional: 0.74
  - Longitudinal: 1.47
  - Overall: 0.79
 Hull space for machinery, storage, compartmentation is cramped
 Room for accommodation and workspaces is excellent
