Cost:
£0.052 million / $0.209 million
Distribution of weights at normal displacement:
Armament: 2 tons, 0.9 %
Machinery: 11 tons, 5.2 %
Hull, fittings & equipment: 82 tons, 37.8 %
Fuel, ammunition & stores: 17 tons, 7.6 %
Miscellaneous weights: 105 tons, 48.4 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
458 lbs / 208 Kg = 35.6 x 3.0 " / 75 mm shells or 0.5 torpedoes
Stability (Unstable if below 1.00): 1.20
Metacentric height 0.7 ft / 0.2 m
Roll period: 10.8 seconds
Steadiness - As gun platform (Average = 50 %): 50 %
- Recoil effect (Restricted arc if above 1.00): 0.04
Seaboat quality (Average = 1.00): 1.14
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.700
Length to Beam Ratio: 7.20 : 1
'Natural speed' for length: 12.42 kts
Power going to wave formation at top speed: 44 %
Trim (Max stability = 0, Max steadiness = 100): 44
Bow angle (Positive = bow angles forward): 40.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 6.56 ft / 2.00 m
- Forecastle (20 %): 5.91 ft / 1.80 m
- Mid (50 %): 5.58 ft / 1.70 m
- Quarterdeck (15 %): 5.58 ft / 1.70 m
- Stern: 5.58 ft / 1.70 m
- Average freeboard: 5.74 ft / 1.75 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 76.9 %
- Above water (accommodation/working, high = better): 105.6 %
Waterplane Area: 2,648 Square feet or 246 Square metres
Displacement factor (Displacement / loading): 151 %
Structure weight / hull surface area: 24 lbs/sq ft or 118 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.99
- Longitudinal: 1.09
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is adequate

Okay, why did everything double-space, and how do I stop it? That's really annoying.
