Estimated overall survivability and seakeeping ability:
        Relative margin of stability: 1.04
        Shellfire needed to sink: 51,815 lbs / 23,503 Kg = 30.7 x 15.0 " / 381 mm shells
        (Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
        Torpedoes needed to sink: 7.8
        (Approx number of typical torpedo hits needed to sink ship)
        Relative steadiness as gun platform: 79 %
        (Average = 50 %)
        Relative rocking effect from firing to beam: 0.41
        Relative quality as seaboat: 1.06
