Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     254 lbs / 115 Kg = 7.2 x 4.1 " / 105 mm shells or 0.2 torpedoes
   Stability (Unstable if below 1.00): 1.24
   Metacentric height 1.0 ft / 0.3 m
   Roll period: 11.1 seconds
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0.18
   Seaboat quality  (Average = 1.00): 0.89

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0.485
   Length to Beam Ratio: 12.00 : 1
   'Natural speed' for length: 17.88 kts
   Power going to wave formation at top speed: 69 %
   Trim (Max stability = 0, Max steadiness = 100): 79
   Bow angle (Positive = bow angles forward): 14.00 degrees
   Stern overhang: -6.56 ft / -2.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      16.40 ft / 5.00 m
      - Forecastle (20 %):   16.40 ft / 5.00 m
      - Mid (50 %):      16.40 ft / 5.00 m (8.20 ft / 2.50 m aft of break)
      - Quarterdeck (15 %):   8.20 ft / 2.50 m
      - Stern:      8.20 ft / 2.50 m
      - Average freeboard:   12.30 ft / 3.75 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 193.5 %
      - Above water (accommodation/working, high = better): 74.0 %
   Waterplane Area: 5,596 Square feet or 520 Square metres
   Displacement factor (Displacement / loading): 46 %
   Structure weight / hull surface area: 26 lbs/sq ft or 129 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 1.53
      - Overall: 0.55
   Hull space for machinery, storage, compartmentation is cramped
   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
