- Conning Tower: 273 tons, 1.0%
Machinery: 3,888 tons, 14.0%
Hull, fittings & equipment: 9,122 tons, 32.7%
Fuel, ammunition & stores: 4,269 tons, 15.3%
Miscellaneous weights: 0 tons, 0.0%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
31,026 lbs / 14,073 Kg = 22.5 x 14.0 " / 356 mm shells or 4.3 torpedoes
Stability (Unstable if below 1.00): 1.22
Metacentric height 6.0 ft / 1.8 m
Roll period: 15.1 seconds
Steadiness - As gun platform (Average = 50 %): 50 %
- Recoil effect (Restricted arc if above 1.00): 0.53
Seaboat quality (Average = 1.00): 1.01
Hull form characteristics:
Hull has a flush deck,
a normal bow and a cruiser stern
Block coefficient (normal/deep): 0.550 / 0.558
Length to Beam Ratio: 7.41 : 1
'Natural speed' for length: 25.62 kts
Power going to wave formation at top speed: 53 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: -1.64 ft / -0.50 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 20.00%, 21.33 ft / 6.50 m, 18.04 ft / 5.50 m
- Forward deck: 30.00%, 18.04 ft / 5.50 m, 18.04 ft / 5.50 m
- Aft deck: 35.00%, 18.04 ft / 5.50 m, 18.04 ft / 5.50 m
- Quarter deck: 15.00%, 18.04 ft / 5.50 m, 18.04 ft / 5.50 m
- Average freeboard: 18.31 ft / 5.58 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 112.4%
- Above water (accommodation/working, high = better): 129.3%
Waterplane Area: 40,565 Square feet or 3,769 Square metres
Displacement factor (Displacement / loading): 102%
Structure weight / hull surface area: 179 lbs/sq ft or 876 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1.01
- Longitudinal: 1.40
- Overall: 1.04
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
