Breech loading guns in deck mounts
on side, all amidships
Weight of broadside 273 lbs / 124 kg
Shells per gun, main battery: 2,500

Machinery:
Coal fired boilers, complex reciprocating steam engines,
Electric motors, 2 shafts, 23,356 ihp / 17,424 Kw = 20.00 kts
Range 27,000nm at 14.00 kts
Bunker at max displacement = 18,536 tons (100% coal)

Complement:
835 - 1,086

Cost:
£0.850 million / $3.400 million

Distribution of weights at normal displacement:
Armament: 32 tons, 0.2 %
Machinery: 1,797 tons, 9.1 %
Hull, fittings & equipment: 4,609 tons, 23.2 %
Fuel, ammunition & stores: 11,099 tons, 56.0 %
Miscellaneous weights: 2,300 tons, 11.6 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
52,481 lbs / 23,805 Kg = 509.6 x 5.9 " / 150 mm shells or 4.8 torpedoes
Stability (Unstable if below 1.00): 1.37
Metacentric height 4.6 ft / 1.4 m
Roll period: 12.8 seconds
Steadiness - As gun platform (Average = 50 %): 100 %
- Recoil effect (Restricted arc if above 1.00): 0.03
Seaboat quality (Average = 1.00): 2.00

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.771
Length to Beam Ratio: 8.50 : 1
'Natural speed' for length: 23.62 kts
Power going to wave formation at top speed: 42 %
Trim (Max stability = 0, Max steadiness = 100): 51
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 26.25 ft / 8.00 m
- Forecastle (15 %): 24.61 ft / 7.50 m
- Mid (50 %): 24.61 ft / 7.50 m
- Quarterdeck (15 %): 24.61 ft / 7.50 m
- Stern: 24.61 ft / 7.50 m
- Average freeboard: 24.70 ft / 7.53 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 46.6 %
- Above water (accommodation/working, high = better): 175.2 %
Waterplane Area: 31,209 Square feet or 2,899 Square metres
Displacement factor (Displacement / loading): 323 %
Structure weight / hull surface area: 91 lbs/sq ft or 443 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.94
- Longitudinal: 1.75
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
