Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
4,403 lbs / 1,997 Kg = 343.0 x 3.0 " / 75 mm shells or 2.2 torpedoes
Stability (Unstable if below 1.00): 1.12
Metacentric height 1.6 ft / 0.5 m
Roll period: 13.4 seconds
Steadiness - As gun platform (Average = 50 %): 51 %
- Recoil effect (Restricted arc if above 1.00): 0.01
Seaboat quality (Average = 1.00): 1.45
Hull form characteristics:
Hull has raised forecastle
Block coefficient: 0.525
Length to Beam Ratio: 5.00 : 1
'Natural speed' for length: 14.14 kts
Power going to wave formation at top speed: 55 %
Trim (Max stability = 0, Max steadiness = 100): 35
Bow angle (Positive = bow angles forward): 20.00 degrees

- Average freeboard: 10.70 ft / 3.26 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 40.4 %
- Above water (accommodation/working, high = better): 71.1 %
Waterplane Area: 5,266 Square feet or 489 Square metres
Displacement factor (Displacement / loading): 306 %
Structure weight / hull surface area: 105 lbs/sq ft or 513 Kg/sq metre
Hull strength (Relative):
