Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
60 281 lbs / 27 343 Kg = 29,4 x 16,0 " / 406 mm shells or 8,4 torpedoes
Stability (Unstable if below 1.00): 1,05
Metacentric height 6,0 ft / 1,8 m
Roll period: 18,2 seconds
Steadiness - As gun platform (Average = 50 %): 58 %
- Recoil effect (Restricted arc if above 1.00): 0,83
Seaboat quality (Average = 1.00): 1,16
Hull form characteristics:
Hull has raised forecastle, rise forward of midbreak
Block coefficient: 0,554
Length to Beam Ratio: 8,49 : 1
'Natural speed' for length: 30,00 kts
Power going to wave formation at top speed: 41 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 38,66 degrees
Stern overhang: -4,50 ft / -1,37 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 30,00 ft / 9,14 m
- Forecastle (20 %): 33,00 ft / 10,06 m (23,00 ft / 7,01 m aft of break)

Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 92,2 %
- Above water (accommodation/working, high = better): 143,7 %
Waterplane Area: 66 829 Square feet or 6 209 Square metres
Displacement factor (Displacement / loading): 99 %

Hull strength (Relative):
- Cross-sectional: 1,03
- Longitudinal: 1,00
- Overall: 1,00
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
