Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     14,461 lbs / 6,559 Kg = 30.3 x 9.8 " / 250 mm shells or 1.9 torpedoes
   Stability (Unstable if below 1.00): 1.15
   Metacentric height 3.4 ft / 1.1 m
   Roll period: 14.8 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0.69
   Seaboat quality  (Average = 1.00): 1.83

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.591
   Length to Beam Ratio: 7.00 : 1
   'Natural speed' for length: 21.43 kts
   Power going to wave formation at top speed: 40 %
   Trim (Max stability = 0, Max steadiness = 100): 28
