Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
14,770 lbs / 6,699 Kg = 17.1 x 12.0 " / 305 mm shells or 2.0 torpedoes
Stability (Unstable if below 1.00): 1.31
Metacentric height 5.0 ft / 1.5 m
Roll period: 13.6 seconds
Steadiness - As gun platform (Average = 50 %): 71 %
- Recoil effect (Restricted arc if above 1.00): 0.35
Seaboat quality (Average = 1.00): 1.48
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.665
Length to Beam Ratio: 5.40 : 1
'Natural speed' for length: 19.85 kts
Power going to wave formation at top speed: 49 %
Trim (Max stability = 0, Max steadiness = 100): 48
Bow angle (Positive = bow angles forward): -5.00 degrees
