Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
485 lbs / 220 Kg = 7.2 x 5.1 " / 130 mm shells or 0.3 torpedoes
Stability (Unstable if below 1.00): 1.15
Metacentric height 1.3 ft / 0.4 m
Roll period: 12.6 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.59
Seaboat quality (Average = 1.00): 1.00
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.400
Length to Beam Ratio: 10.88 : 1
'Natural speed' for length: 22.10 kts
Power going to wave formation at top speed: 66 %
Trim (Max stability = 0, Max steadiness = 100): 70
Bow angle (Positive = bow angles forward): 0.00 degrees

- Stern: 14.00 ft / 4.27 m
- Average freeboard: 14.64 ft / 4.46 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 176.2%
- Above water (accommodation/working, high = better): 92.0%
Waterplane Area: 8,036 Square feet or 747 Square metres
Displacement factor (Displacement / loading): 71%
Structure weight / hull surface area: 35 lbs/sq ft or 173 Kg/sq metre
