Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
34,105 lbs / 15,470 Kg = 133.2 x 8.0 " / 203 mm shells or 3.5 torpedoes
Stability (Unstable if below 1.00): 1.05
Metacentric height 3.8 ft / 1.1 m
Roll period: 16.9 seconds
Steadiness - As gun platform (Average = 50 %): 86 %
- Recoil effect (Restricted arc if above 1.00): 0.01
Seaboat quality (Average = 1.00): 1.85
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.532
Length to Beam Ratio: 8.80 : 1
'Natural speed' for length: 30.07 kts
Power going to wave formation at top speed: 56 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 28.80 ft / 8.78 m
- Forecastle (20 %): 18.33 ft / 5.59 m
- Mid (50 %): 18.33 ft / 5.59 m
