Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
715 lbs / 324 Kg = 11.2 x 5.0 " / 128 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.23
Metacentric height 1.7 ft / 0.5 m
Roll period: 12.1 seconds
Steadiness - As gun platform (Average = 50 %): 52 %
- Recoil effect (Restricted arc if above 1.00): 0.49
Seaboat quality (Average = 1.00): 1.05

Hull has a flush deck,
a normal bow and small transom stern
Block coefficient (normal/deep): 0.420 / 0.431
Length to Beam Ratio: 10.53 : 1
'Natural speed' for length: 22.79 kts
