Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     24,723 lbs / 11,214 Kg = 51.9 x 9.8 " / 250 mm shells or 6.9 torpedoes
   Stability (Unstable if below 1.00): 1.47
   Metacentric height 26.5 ft / 8.1 m
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0.02
   Seaboat quality  (Average = 1.00): 0.88

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.654
   Length to Beam Ratio: 1.00 : 1
   'Natural speed' for length: 13.96 kts
   Power going to wave formation at top speed: 53 %
   Trim (Max stability = 0, Max steadiness = 100): 80
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      10.00 ft / 3.05 m
      - Forecastle (20 %):   10.00 ft / 3.05 m
      - Mid (50 %):      10.00 ft / 3.05 m
      - Quarterdeck (15 %):   10.00 ft / 3.05 m
      - Stern:      10.00 ft / 3.05 m
      - Average freeboard:   10.00 ft / 3.05 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 53.1 %
      - Above water (accommodation/working, high = better): 87.8 %
   Waterplane Area: 28,845 Square feet or 2,680 Square metres
   Displacement factor (Displacement / loading): 113 %
   Structure weight / hull surface area: 192 lbs/sq ft or 938 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.83
      - Longitudinal: 5.07
      - Overall: 1.00
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is cramped
   Ship has slow, easy roll, a good, steady gun platform
   Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
