Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     20 264 lbs / 9 191 Kg = 20,3 x 12,6 " / 320 mm shells or 3,7 torpedoes
   Stability (Unstable if below 1.00): 1,08
   Metacentric height 4,3 ft / 1,3 m
   Roll period: 16,6 seconds
   Steadiness   - As gun platform (Average = 50 %): 66 %
         - Recoil effect (Restricted arc if above 1.00): 0,64
   Seaboat quality  (Average = 1.00): 1,31

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,550
   Length to Beam Ratio: 5,40 : 1
   'Natural speed' for length: 21,05 kts
   Power going to wave formation at top speed: 55 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   Bow angle (Positive = bow angles forward): 10,00 degrees
   Stern overhang: 0,00 ft / 0,00 m
   Freeboard (% = measuring location as a percentage of overall length):
