Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):

    Stability (Unstable if below 1.00): 1,07
    Metacentric height 3,3 ft / 1,0 m
    Roll period: 16,1 seconds
    Steadiness    - As gun platform (Average = 50 %): 56 %
            - Recoil effect (Restricted arc if above 1.00): 0,69
    Seaboat quality  (Average = 1.00): 1,39

Hull form characteristics:
    Hull has rise forward of midbreak
    Block coefficient: 0,563
    Length to Beam Ratio: 6,41 : 1
    'Natural speed' for length: 21,13 kts
    Power going to wave formation at top speed: 43 %
    Trim (Max stability = 0, Max steadiness = 100): 40
    Bow angle (Positive = bow angles forward): -15,50 degrees
    Stern overhang: 0,00 ft / 0,00 m
    Freeboard (% = measuring location as a percentage of overall length):
       - Stem:        19,91 ft / 6,07 m
       - Forecastle (14%):    18,60 ft / 5,67 m
       - Mid (72%):        18,60 ft / 5,67 m (10,24 ft / 3,12 m aft of break)
       - Quarterdeck (13%):    10,24 ft / 3,12 m
       - Stern:        10,24 ft / 3,12 m
       - Average freeboard:    16,30 ft / 4,97 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 133,0%
        - Above water (accommodation/working, high = better): 112,6%
    Waterplane Area: 21 968 Square feet or 2 041 Square metres
    Displacement factor (Displacement / loading): 96%
    Structure weight / hull surface area: 139 lbs/sq ft or 679 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,94
        - Longitudinal: 1,74
        - Overall: 1,00
    Hull space for machinery, storage, compartmentation is cramped
    Room for accommodation and workspaces is adequate
    Good seaboat, rides out heavy weather easily
