    Stability (Unstable if below 1.00): 1,04
    Metacentric height 4,2 ft / 1,3 m
    Roll period: 17,4 seconds
    Steadiness    - As gun platform (Average = 50 %): 63 %
            - Recoil effect (Restricted arc if above 1.00): 0,69

    Hull has a flush deck
    Block coefficient: 0,558
    Length to Beam Ratio: 5,65 : 1
    'Natural speed' for length: 21,86 kts
    Power going to wave formation at top speed: 48 %
    Trim (Max stability = 0, Max steadiness = 100): 50
