Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
334 lbs / 151 Kg = 5.3 x 5.0 " / 127 mm shells or 0.2 torpedoes
Stability (Unstable if below 1.00): 1.13
Metacentric height 0.9 ft / 0.3 m
Roll period: 12.0 seconds
Steadiness - As gun platform (Average = 50 %): 71 %
- Recoil effect (Restricted arc if above 1.00): 0.54
Seaboat quality (Average = 1.00): 1.07
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.440
Length to Beam Ratio: 11.11 : 1
'Natural speed' for length: 19.75 kts
Power going to wave formation at top speed: 69 %
