Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
4 605 lbs / 2 089 Kg = 35,6 x 7,6 " / 194 mm shells or 0,7 torpedoes
Stability (Unstable if below 1.00): 1,53
Metacentric height 4,7 ft / 1,4 m
Roll period: 11,5 seconds
Steadiness - As gun platform (Average = 50 %): 98 %
- Recoil effect (Restricted arc if above 1.00): 0,49
Seaboat quality (Average = 1.00): 1,97
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,590
Length to Beam Ratio: 5,96 : 1
'Natural speed' for length: 18,73 kts
Power going to wave formation at top speed: 37 %
