Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
672 lbs / 305 Kg = 10.7 x 5.0 " / 127 mm shells or 0.3 torpedoes
Stability (Unstable if below 1.00): 1.23
Metacentric height 2.0 ft / 0.6 m
Roll period: 12.4 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.52
Seaboat quality (Average = 1.00): 1.02

Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0.380
Length to Beam Ratio: 10.91 : 1
'Natural speed' for length: 21.24 kts
Power going to wave formation at top speed: 63 %
Trim (Max stability = 0, Max steadiness = 100): 68
Bow angle (Positive = bow angles forward): 35.00 degrees
Stern overhang: 5.41 ft / 1.65 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 22.97 ft / 7.00 m
