Miscellaneous weights: 3 tons, 3.9 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
213 lbs / 97 Kg = 67.3 x 1.9 " / 47 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.16
Metacentric height 0.4 ft / 0.1 m
Roll period: 10.2 seconds
Steadiness - As gun platform (Average = 50 %): 50 %
- Recoil effect (Restricted arc if above 1.00): 0.13
Seaboat quality (Average = 1.00): 1.02

Hull form characteristics:

'Natural speed' for length: 10.49 kts
Power going to wave formation at top speed: 60 %
Trim (Max stability = 0, Max steadiness = 100): 49
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
