Distribution of weights at normal displacement:
Armament: 63 tons, 2.5 %
Armour: 32 tons, 1.3 %
- Belts: 0 tons, 0.0 %
- Torpedo bulkhead: 0 tons, 0.0 %
- Armament: 32 tons, 1.3 %
- Armour Deck: 0 tons, 0.0 %
- Conning Tower: 0 tons, 0.0 %
Machinery: 1,211 tons, 47.6 %
Hull, fittings & equipment: 787 tons, 31.0 %
Fuel, ammunition & stores: 378 tons, 14.9 %
Miscellaneous weights: 70 tons, 2.8 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
778 lbs / 353 Kg = 11.6 x 5.1 " / 130 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.33
Metacentric height 2.0 ft / 0.6 m
Roll period: 11.4 seconds
Steadiness - As gun platform (Average = 50 %): 51 %
- Recoil effect (Restricted arc if above 1.00): 0.52
Seaboat quality (Average = 1.00): 1.01
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.470
Length to Beam Ratio: 10.92 : 1
'Natural speed' for length: 23.17 kts
Power going to wave formation at top speed: 66 %
Trim (Max stability = 0, Max steadiness = 100): 50
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: 22.00 ft / 6.71 m
- Forecastle (20 %): 17.00 ft / 5.18 m
- Mid (50 %): 16.00 ft / 4.88 m
- Quarterdeck (15 %): 16.00 ft / 4.88 m
- Stern: 17.00 ft / 5.18 m
- Average freeboard: 16.83 ft / 5.13 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 175.9 %
- Above water (accommodation/working, high = better): 88.8 %
Waterplane Area: 10,631 Square feet or 988 Square metres
Displacement factor (Displacement / loading): 75 %
Structure weight / hull surface area: 39 lbs/sq ft or 191 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.50
- Longitudinal: 1.59
- Overall: 0.56
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is cramped
