Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
753 lbs / 342 Kg = 11.2 x 5.1 " / 130 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.38
Metacentric height 2.4 ft / 0.7 m
Roll period: 11.4 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.31
Seaboat quality (Average = 1.00): 1.00
Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.400
Length to Beam Ratio: 11.76 : 1
'Natural speed' for length: 25.33 kts
