Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
29,248 lbs / 13,267 Kg = 75.1 x 9.2 " / 234 mm shells or 4.0 torpedoes
Stability (Unstable if below 1.00): 1.15
Metacentric height 4.6 ft / 1.4 m
Roll period: 15.6 seconds
Steadiness - As gun platform (Average = 50 %): 64 %
- Recoil effect (Restricted arc if above 1.00): 0.77
Seaboat quality (Average = 1.00): 1.27
Hull form characteristics:
Hull has low quarterdeck ,
a ram bow and a cruiser stern
Block coefficient (normal/deep): 0.635 / 0.644
Length to Beam Ratio: 7.06 : 1
'Natural speed' for length: 23.77 kts
Power going to wave formation at top speed: 54 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): -3.00 degrees
Stern overhang: -3.00 ft / -0.91 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 20.00 %, 27.00 ft / 8.23 m, 26.00 ft / 7.92 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 111.7 %
- Above water (accommodation/working, high = better): 197.6 %
Waterplane Area: 34,151 Square feet or 3,173 Square metres
Displacement factor (Displacement / loading): 107 %
Structure weight / hull surface area: 145 lbs/sq ft or 708 Kg/sq metre
