Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      4 852 lbs / 2 201 Kg = 4,3 x 14,0 " / 356 mm shells or 1,1 torpedoes
    Stability (Unstable if below 1.00): 1,29
    Metacentric height 3,5 ft / 1,1 m
    Roll period: 13,0 seconds
    Steadiness    - As gun platform (Average = 50 %): 97 %
            - Recoil effect (Restricted arc if above 1.00): 0,41
    Seaboat quality  (Average = 1.00): 1,93

    Hull has a flush deck
    Block coefficient: 0,599
    Length to Beam Ratio: 4,28 : 1
    'Natural speed' for length: 15,79 kts
    Power going to wave formation at top speed: 48 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): -9,00 degrees
    Stern overhang: 0,00 ft / 0,00 m
    Freeboard (% = measuring location as a percentage of overall length):
