Distribution of weights at normal displacement:
Armament: 0 tons, 0.0 %
Machinery: 61 tons, 60.8 %
Hull, fittings & equipment: 29 tons, 29.4 %
Fuel, ammunition & stores: 10 tons, 9.8 %
Miscellaneous weights: 0 tons, 0.0 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
21 lbs / 9 Kg = 334.8 x 0.5 " / 13 mm shells or 0.1 torpedoes
Stability (Unstable if below 1.00): 1.16
Metacentric height 0.3 ft / 0.1 m
Roll period: 9.6 seconds
Steadiness - As gun platform (Average = 50 %): 99 %
- Recoil effect (Restricted arc if above 1.00): 0.01
Seaboat quality (Average = 1.00): 1.98

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.405
Length to Beam Ratio: 10.00 : 1
'Natural speed' for length: 10.95 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: 12.05 ft / 3.67 m
- Forecastle (20 %): 7.67 ft / 2.34 m
- Mid (50 %): 7.67 ft / 2.34 m
- Quarterdeck (15 %): 7.67 ft / 2.34 m
- Stern: 7.67 ft / 2.34 m
- Average freeboard: 8.02 ft / 2.44 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 196.3 %
- Above water (accommodation/working, high = better): 49.8 %
Waterplane Area: 889 Square feet or 83 Square metres
Displacement factor (Displacement / loading): 20 %
Structure weight / hull surface area: 10 lbs/sq ft or 49 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.38
- Longitudinal: 7.70
- Overall: 0.51
Caution: Hull subject to strain in open-sea

Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is extremely poor
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
