Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
553 lbs / 251 Kg = 13,6 x 4,3 " / 110 mm shells or 0,3 torpedoes
Stability (Unstable if below 1.00): 1,47
Metacentric height 2,4 ft / 0,7 m
Roll period: 10,7 seconds
Steadiness - As gun platform (Average = 50 %): 52 %
- Recoil effect (Restricted arc if above 1.00): 0,16
Seaboat quality (Average = 1.00): 1,03
Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0,400
Length to Beam Ratio: 10,00 : 1
'Natural speed' for length: 19,84 kts
Power going to wave formation at top speed: 66 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 35,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 25,10 ft / 7,65 m
- Forecastle (20%): 20,34 ft / 6,20 m
