- Hull below water: 25 tons
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
396 lbs / 179 Kg = 6.3 x 5.0 " / 127 mm shells or 0.2 torpedoes
Stability (Unstable if below 1.00): 1.27
Metacentric height 1.6 ft / 0.5 m
Roll period: 11.7 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.25
Seaboat quality (Average = 1.00): 0.83
Hull form characteristics:
Hull has a flush deck,
a normal bow and large transom stern
Block coefficient (normal/deep): 0.410 / 0.423
Length to Beam Ratio: 10.00 : 1
'Natural speed' for length: 21.74 kts
Power going to wave formation at top speed: 70 %
Trim (Max stability = 0, Max steadiness = 100): 85
Bow angle (Positive = bow angles forward): 32.00 degrees
Stern overhang: 3.94 ft / 1.20 m
Freeboard (% = length of deck as a percentage of waterline length):

- Quarter deck: 17.00%, 13.19 ft / 4.02 m, 13.19 ft / 4.02 m
- Average freeboard: 14.76 ft / 4.50 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 193.3%
- Above water (accommodation/working, high = better): 115.0%
Waterplane Area: 8,070 Square feet or 750 Square metres
Displacement factor (Displacement / loading): 61%
Structure weight / hull surface area: 31 lbs/sq ft or 152 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.45
- Longitudinal: 1.63
- Overall: 0.51
Cramped machinery, storage, compartmentation space
Adequate accommodation and workspace room
Ship has slow, easy roll, a good, steady gun platform
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
