Hull, fittings & equipment: 3,907 tons, 44.5 %
Fuel, ammunition & stores: 219 tons, 2.5 %
Miscellaneous weights: 750 tons, 8.5 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
6,057 lbs / 2,747 Kg = 56.1 x 6 " / 152 mm shells or 1.0 torpedoes
Stability (Unstable if below 1.00): 1.21
Metacentric height 3.8 ft / 1.2 m
Roll period: 14.3 seconds

- Recoil effect (Restricted arc if above 1.00): 0.00
Seaboat quality (Average = 1.00): 1.00
Hull form characteristics:
Hull has raised forecastle, rise forward of midbreak, low quarterdeck
and transom stern
Block coefficient: 0.405
Length to Beam Ratio: 8.18 : 1
'Natural speed' for length: 27.46 kts
Power going to wave formation at top speed: 69 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): -57.00 degrees
Stern overhang: 25.12 ft / 7.66 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 29.68 ft / 9.05 m

- Mid (50 %): 25.28 ft / 7.71 m (25.15 ft / 7.67 m aft of break)
- Quarterdeck (15 %): 25.12 ft / 7.66 m (25.15 ft / 7.67 m before break)
- Stern: 25.15 ft / 7.67 m
- Average freeboard: 26.22 ft / 7.99 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 153.1 %
- Above water (accommodation/working, high = better): 251.0 %
Waterplane Area: 23,257 Square feet or 2,161 Square metres
Displacement factor (Displacement / loading): 103 %
Structure weight / hull surface area: 96 lbs/sq ft or 469 Kg/sq metre
