Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     605 lbs / 274 Kg = 5,6 x 6,0 " / 152 mm shells or 0,3 torpedoes
   Stability (Unstable if below 1.00): 1,29
   Metacentric height 1,5 ft / 0,5 m
   Roll period: 11,3 seconds
   Steadiness   - As gun platform (Average = 50 %): 71 %
         - Recoil effect (Restricted arc if above 1.00): 0,81
   Seaboat quality  (Average = 1.00): 1,34

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,415
   Length to Beam Ratio: 11,91 : 1
   'Natural speed' for length: 19,82 kts
   Power going to wave formation at top speed: 55 %
   Trim (Max stability = 0, Max steadiness = 100): 53
   Bow angle (Positive = bow angles forward): 1,00 degrees
   Stern overhang: 0,33 ft / 0,10 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      21,80 ft / 6,64 m
      - Forecastle (12%):   17,50 ft / 5,33 m
      - Mid (30%):      17,50 ft / 5,33 m (11,00 ft / 3,35 m aft of break)
      - Quarterdeck (15%):   11,00 ft / 3,35 m
      - Stern:      11,00 ft / 3,35 m
      - Average freeboard:   13,16 ft / 4,01 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 158,2%
      - Above water (accommodation/working, high = better): 88,4%
   Waterplane Area: 8.058 Square feet or 749 Square metres
   Displacement factor (Displacement / loading): 87%
   Structure weight / hull surface area: 35 lbs/sq ft or 169 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,51
      - Longitudinal: 1,06
      - Overall: 0,54
   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
   Good seaboat, rides out heavy weather easily
