Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
18 728 lbs / 8 495 Kg = 21,6 x 12,0 " / 305 mm shells or 1,9 torpedoes
Stability (Unstable if below 1.00): 1,35
Metacentric height 6,0 ft / 1,8 m
Roll period: 13,6 seconds
Steadiness - As gun platform (Average = 50 %): 39 %
- Recoil effect (Restricted arc if above 1.00): 0,28
Seaboat quality (Average = 1.00): 0,62
Hull form characteristics:
Hull has raised forecastle
Block coefficient: 0,553
Length to Beam Ratio: 8,37 : 1
'Natural speed' for length: 25,78 kts
Power going to wave formation at top speed: 61 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 20,20 degrees
Stern overhang: 4,27 ft / 1,30 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 28,22 ft / 8,60 m

Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 110,8%
- Above water (accommodation/working, high = better): 148,2%
Waterplane Area: 36 916 Square feet or 3 430 Square metres
Displacement factor (Displacement / loading): 101%
Structure weight / hull surface area: 137 lbs/sq ft or 667 Kg/sq metre
