Metacentric height 1,8 ft / 0,5 m
Roll period: 12,6 seconds
Steadiness - As gun platform (Average = 50 %): 88 %
- Recoil effect (Restricted arc if above 1.00): 0,53
Seaboat quality (Average = 1.00): 1,76

Hull form characteristics:
Hull has raised forecastle
Block coefficient: 0,661
Length to Beam Ratio: 8,25 : 1
'Natural speed' for length: 18,17 kts
Power going to wave formation at top speed: 55 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 1,00 degrees
Stern overhang: -5,00 ft / -1,52 m
Freeboard (% = measuring location as a percentage of overall length):
