Steadiness - As gun platform (Average = 50 %): 100 %
- Recoil effect (Restricted arc if above 1.00): 0,00
Seaboat quality (Average = 1.00): 2,00
Hull form characteristics:
Hull has raised forecastle, raised quarterdeck
Block coefficient: 0,630
Length to Beam Ratio: 5,75 : 1
'Natural speed' for length: 14,58 kts
Power going to wave formation at top speed: 32 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 12,00 degrees
Stern overhang: 4,27 ft / 1,30 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 17,39 ft / 5,30 m
