Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
4,839 lbs / 2,195 Kg = 137.0 x 4.1 " / 105 mm shells or 2.3 torpedoes
Stability (Unstable if below 1.00): 1.13
Metacentric height 1.8 ft / 0.5 m
Roll period: 13.5 seconds
Steadiness - As gun platform (Average = 50 %): 51 %
- Recoil effect (Restricted arc if above 1.00): 0.03
Seaboat quality (Average = 1.00): 1.95
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.451
Length to Beam Ratio: 5.38 : 1
'Natural speed' for length: 15.15 kts
Power going to wave formation at top speed: 25 %
Trim (Max stability = 0, Max steadiness = 100): 26
Bow angle (Positive = bow angles forward): 59.00 degrees
