Miscellaneous weights: 0 tons, 0.0%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
8,349 lbs / 3,787 Kg = 32.7 x 8.0 " / 203 mm shells or 1.5 torpedoes
Stability (Unstable if below 1.00): 1.16
Metacentric height 2.7 ft / 0.8 m
Roll period: 14.1 seconds
Steadiness - As gun platform (Average = 50 %): 47 %
- Recoil effect (Restricted arc if above 1.00): 0.65
Seaboat quality (Average = 1.00): 0.89
Hull form characteristics:
Hull has a flush deck,
a normal bow and a cruiser stern
Block coefficient (normal/deep): 0.550 / 0.556
Length to Beam Ratio: 8.24 : 1
'Natural speed' for length: 21.43 kts
Power going to wave formation at top speed: 60 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 5.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 20.00%, 19.69 ft / 6.00 m, 18.04 ft / 5.50 m
- Forward deck: 30.00%, 18.04 ft / 5.50 m, 18.04 ft / 5.50 m
- Aft deck: 30.00%, 18.04 ft / 5.50 m, 18.04 ft / 5.50 m
- Quarter deck: 20.00%, 18.04 ft / 5.50 m, 18.04 ft / 5.50 m
- Average freeboard: 18.18 ft / 5.54 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 163.9%
- Above water (accommodation/working, high = better): 141.6%
Waterplane Area: 17,879 Square feet or 1,661 Square metres
Displacement factor (Displacement / loading): 103%
Structure weight / hull surface area: 112 lbs/sq ft or 547 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1.02
- Longitudinal: 1.86
- Overall: 1.08
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
