Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
717 lbs / 325 Kg = 17.6 x 4.3 " / 110 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.20

Roll period: 12.6 seconds
Steadiness - As gun platform (Average = 50 %): 71 %
- Recoil effect (Restricted arc if above 1.00): 0.39
Seaboat quality (Average = 1.00): 1.02
Hull form characteristics:
Hull has raised forecastle
and transom stern
Block coefficient: 0.400
Length to Beam Ratio: 10.42 : 1
'Natural speed' for length: 23.34 kts
Power going to wave formation at top speed: 65 %
