Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
54,241 lbs / 24,603 Kg = 62.8 x 12.0 " / 305 mm shells or 9.3 torpedoes
Stability (Unstable if below 1.00): 1.25
Metacentric height 8.0 ft / 2.4 m
Roll period: 15.6 seconds
Steadiness - As gun platform (Average = 50 %): 80 %
- Recoil effect (Restricted arc if above 1.00): 0.46
Seaboat quality (Average = 1.00): 1.61
Hull form characteristics:
Hull has rise forward of midbreak,
a normal bow and a cruiser stern
Block coefficient (normal/deep): 0.545 / 0.553
Length to Beam Ratio: 6.10 : 1
'Natural speed' for length: 25.30 kts
Power going to wave formation at top speed: 49 %
Trim (Max stability = 0, Max steadiness = 100): 50

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 79.2 %
- Above water (accommodation/working, high = better): 209.6 %
Waterplane Area: 46,679 Square feet or 4,337 Square metres
Displacement factor (Displacement / loading): 118 %
Structure weight / hull surface area: 178 lbs/sq ft or 871 Kg/sq metre
