Hull form characteristics:
Hull has low quarterdeck
Block coefficient: 0,706
Length to Beam Ratio: 6,99 : 1
'Natural speed' for length: 29,09 kts
Power going to wave formation at top speed: 48 %
Trim (Max stability = 0, Max steadiness = 100): 35
Bow angle (Positive = bow angles forward): 26,55 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 32,81 ft / 10,00 m
