Cost:
£0.288 million / $1.153 million
Distribution of weights at normal displacement:
Armament: 125 tons, 8.5%
- Guns: 125 tons, 8.5%
Armour: 480 tons, 32.6%
- Armament: 121 tons, 8.2%
- Armour Deck: 347 tons, 23.6%
- Conning Towers: 12 tons, 0.8%
Machinery: 63 tons, 4.3%
Hull, fittings & equipment: 542 tons, 36.8%
Fuel, ammunition & stores: 213 tons, 14.5%
Miscellaneous weights: 50 tons, 3.4%
- Hull below water: 10 tons

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
6,391 lbs / 2,899 Kg = 12.8 x 10.0 " / 254 mm shells or 3.8 torpedoes
Stability (Unstable if below 1.00): 2.08
Metacentric height 11.7 ft / 3.6 m
Roll period: 10.1 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.03
Seaboat quality (Average = 1.00): 0.80
Hull form characteristics:
Hull has low forecastle, low quarterdeck ,
a normal bow and small transom stern
Block coefficient (normal/deep): 0.365 / 0.372
Length to Beam Ratio: 4.00 : 1
'Natural speed' for length: 20.86 kts
Power going to wave formation at top speed: 21 %
Trim (Max stability = 0, Max steadiness = 100): 88
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 30.00%, 5.25 ft / 1.60 m, 5.25 ft / 1.60 m
- Forward deck: 30.00%, 13.12 ft / 4.00 m, 13.12 ft / 4.00 m
- Aft deck: 10.00%, 13.12 ft / 4.00 m, 13.12 ft / 4.00 m
- Quarter deck: 30.00%, 5.25 ft / 1.60 m, 5.25 ft / 1.60 m
- Average freeboard: 8.40 ft / 2.56 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 43.3%
- Above water (accommodation/working, high = better): 351.1%
Waterplane Area: 16,573 Square feet or 1,540 Square metres
Displacement factor (Displacement / loading): 149%
Structure weight / hull surface area: 40 lbs/sq ft or 196 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.49
- Longitudinal: 0.60
- Overall: 0.50
Excellent machinery, storage, compartmentation space
Excellent accommodation and workspace room
Ship has slow, easy roll, a good, steady gun platform
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
Warning: Calibre too large for QF, AA or DP gun - Main Battery
