Fuel, ammunition & stores: 26 tons, 6.5 %
Miscellaneous weights: 75 tons, 18.7 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
27 lbs / 12 Kg = 0.9 x 3.9 " / 100 mm shells or 0.1 torpedoes
Stability (Unstable if below 1.00): 1.03
Metacentric height 0.3 ft / 0.1 m
Roll period: 16.4 seconds
Steadiness - As gun platform (Average = 50 %): 7 %
- Recoil effect (Restricted arc if above 1.00): 0.01
Seaboat quality (Average = 1.00): 0.02
Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0.415
Length to Beam Ratio: 6.67 : 1
'Natural speed' for length: 11.46 kts
Power going to wave formation at top speed: 56 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 30.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 1.64 ft / 0.50 m
- Forecastle (20 %): 1.64 ft / 0.50 m
- Mid (50 %): 1.64 ft / 0.50 m (0.00 ft / 0.00 m aft of break)
- Quarterdeck (15 %): 0.00 ft / 0.00 m
- Stern: 0.00 ft / 0.00 m
- Average freeboard: 0.82 ft / 0.25 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 281.0 %
- Above water (accommodation/working, high = better): 3.5 %
Waterplane Area: 1,070 Square feet or 99 Square metres
Displacement factor (Displacement / loading): 243 %
Structure weight / hull surface area: 113 lbs/sq ft or 553 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 3.81
- Longitudinal: 6.20
- Overall: 4.00
Hull space for machinery, storage, compartmentation is extremely poor
Room for accommodation and workspaces is extremely poor
Ship has quick, lively roll, not a steady gun platform
Caution: Lacks seaworthiness - very limited seakeeping ability
Dive depth - 400'
Emergency depth - 640'
Crush depth - 1000'
