Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     7,565 lbs / 3,431 Kg = 17.2 x 10.2 " / 260 mm shells or 1.2 torpedoes
   Stability (Unstable if below 1.00): 1.70
   Metacentric height 5.6 ft / 1.7 m
   Roll period: 10.7 seconds
   Steadiness   - As gun platform (Average = 50 %): 71 %
         - Recoil effect (Restricted arc if above 1.00): 0.16
   Seaboat quality  (Average = 1.00): 1.74

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.675
   Length to Beam Ratio: 5.33 : 1
   'Natural speed' for length: 17.93 kts
   Power going to wave formation at top speed: 46 %
   Trim (Max stability = 0, Max steadiness = 100): 41
   Bow angle (Positive = bow angles forward): 0.00 degrees
