Cost:
£0.472 million / $1.889 million

Distribution of weights at normal displacement:
Armament: 0 tons, 0.0 %
Machinery: 119 tons, 3.5 %
Hull, fittings & equipment: 1,204 tons, 35.9 %
Fuel, ammunition & stores: 1,583 tons, 47.2 %
Miscellaneous weights: 450 tons, 13.4 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
17,080 lbs / 7,747 Kg = 158.2 x 6 " / 152 mm shells or 4.8 torpedoes
Stability (Unstable if below 1.00): 1.10
Metacentric height 1.9 ft / 0.6 m
Roll period: 14.1 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.00
Seaboat quality (Average = 1.00): 2.00

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.470
Length to Beam Ratio: 5.73 : 1
'Natural speed' for length: 16.23 kts
Power going to wave formation at top speed: 49 %
Trim (Max stability = 0, Max steadiness = 100): 35
Bow angle (Positive = bow angles forward): 45.00 degrees
Stern overhang: 13.12 ft / 4.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 31.17 ft / 9.50 m
- Forecastle (20 %): 27.89 ft / 8.50 m
- Mid (50 %): 25.59 ft / 7.80 m
- Quarterdeck (15 %): 26.57 ft / 8.10 m
- Stern: 27.89 ft / 8.50 m
- Average freeboard: 27.08 ft / 8.25 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 27.7 %
- Above water (accommodation/working, high = better): 172.1 %
Waterplane Area: 7,501 Square feet or 697 Square metres
Displacement factor (Displacement / loading): 488 %
Structure weight / hull surface area: 57 lbs/sq ft or 276 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.72
- Longitudinal: 20.67
- Overall: 1.01
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, rides out heavy weather easily

2446 tons of bunker fuel simmed as deep-stowed ballast. Engine develops maximum 12 knots with max 4,000nm cruising (283 tons bunker fuel)
