Stability (Unstable if below 1.00): 1,26
Metacentric height 4,2 ft / 1,3 m
Roll period: 13,8 seconds
Steadiness - As gun platform (Average = 50 %): 73 %
- Recoil effect (Restricted arc if above 1.00): 0,51
Seaboat quality (Average = 1.00): 1,47
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,625
Length to Beam Ratio: 5,10 : 1
'Natural speed' for length: 18,52 kts
Power going to wave formation at top speed: 47 %
