Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
232 lbs / 105 Kg = 7.3 x 4.0 " / 102 mm shells or 0.2 torpedoes

Metacentric height 1.4 ft / 0.4 m
Roll period: 11.2 seconds
Steadiness - As gun platform (Average = 50 %): 60 %
- Recoil effect (Restricted arc if above 1.00): 0.18
Seaboat quality (Average = 1.00): 0.82

Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0.422
Length to Beam Ratio: 10.16 : 1
'Natural speed' for length: 18.03 kts
Power going to wave formation at top speed: 71 %
Trim (Max stability = 0, Max steadiness = 100): 73
Bow angle (Positive = bow angles forward): 15.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 21.00 ft / 6.40 m
- Forecastle (30 %): 20.00 ft / 6.10 m
- Mid (40 %): 20.00 ft / 6.10 m (10.00 ft / 3.05 m aft of break)
- Quarterdeck (10 %): 10.00 ft / 3.05 m
- Stern: 10.00 ft / 3.05 m
- Average freeboard: 14.12 ft / 4.30 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 207.3 %
- Above water (accommodation/working, high = better): 79.0 %
Waterplane Area: 6,493 Square feet or 603 Square metres
Displacement factor (Displacement / loading): 40 %
Structure weight / hull surface area: 28 lbs/sq ft or 136 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.43
- Longitudinal: 1.78
- Overall: 0.50
Hull space for machinery, storage, compartmentation is extremely poor
Room for accommodation and workspaces is cramped
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
