Miscellaneous weights: 2.000 tons, 25,4%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
14.951 lbs / 6.781 Kg = 423,3 x 4,1 " / 105 mm shells or 2,6 torpedoes
Stability (Unstable if below 1.00): 1,13
Metacentric height 3,3 ft / 1,0 m
Roll period: 15,0 seconds
Steadiness - As gun platform (Average = 50 %): 61 %
- Recoil effect (Restricted arc if above 1.00): 0,03
Seaboat quality (Average = 1.00): 1,23
Hull form characteristics:
