Overall survivability and seakeeping
ability:
Survivability (Non-critical penetrating hits needed to sink ship):
41,684 lbs / 18,907 Kg = 24.7 x 15.0 "
/ 381 mm shells or 5.9 torpedoes
Stability (Unstable if below 1.00): 1.02
Metacentric height 5.9 ft / 1.8 m
Roll
period: 18.8 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above
1.00): 0.81
Seaboat quality (Average = 1.00): 1.04
Hull form characteristics:
Hull has raised forecastle,
rise forward of midbreak
Block coefficient: 0.560
Length to Beam Ratio: 7.05 : 1
'Natural speed' for length: 27.71
kts
Power going to wave formation at top speed: 47 %
Trim (Max stability = 0, Max steadiness = 100): 67
