Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
322 lbs / 146 Kg = 7.9 x 4.3 " / 110 mm shells or 0.2 torpedoes
Stability (Unstable if below 1.00): 1.03
Metacentric height 0.9 ft / 0.3 m
Roll period: 13.6 seconds
Steadiness - As gun platform (Average = 50 %): 65 %
- Recoil effect (Restricted arc if above 1.00): 0.71
Seaboat quality (Average = 1.00): 0.82

Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.420
Length to Beam Ratio: 10.42 : 1
'Natural speed' for length: 20.82 kts
Power going to wave formation at top speed: 69 %
Trim (Max stability = 0, Max steadiness = 100): 80
Bow angle (Positive = bow angles forward): 25.00 degrees
Stern overhang: 3.28 ft / 1.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 24.61 ft / 7.50 m

Waterplane Area: 6,688 Square feet or 621 Square metres
Displacement factor (Displacement / loading): 57 %
Structure weight / hull surface area: 34 lbs/sq ft or 167 Kg/sq metre

Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is cramped
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
