Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
1,600 lbs / 726 Kg = 30.4 x 4.7 " / 120 mm shells or 0.8 torpedoes
Stability (Unstable if below 1.00): 1.07
Metacentric height 0.9 ft / 0.3 m
Roll period: 12.9 seconds
Steadiness - As gun platform (Average = 50 %): 0 %
- Recoil effect (Restricted arc if above 1.00): 0.00
Seaboat quality (Average = 1.00): 0.00

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.500
Length to Beam Ratio: 11.03 : 1
'Natural speed' for length: 17.89 kts
Power going to wave formation at top speed: 37 %
Trim (Max stability = 0, Max steadiness = 100): 50
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):
- Stem: 0.00 ft / 0.00 m
- Forecastle (20 %): 0.00 ft / 0.00 m
- Mid (50 %): 0.00 ft / 0.00 m
- Quarterdeck (15 %): 0.00 ft / 0.00 m
- Stern: 0.00 ft / 0.00 m
- Average freeboard: 0.00 ft / 0.00 m
Ship tends to be wet forward

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 76.8 %
- Above water (accommodation/working, high = better): 0.0 %
Waterplane Area: 6,183 Square feet or 574 Square metres
Displacement factor (Displacement / loading): 293 %
Structure weight / hull surface area: 152 lbs/sq ft or 741 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 3.71
- Longitudinal: 1.54
- Overall: 1.92
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is extremely poor
Ship has quick, lively roll, not a steady gun platform
Caution: Lacks seaworthiness - very limited seakeeping ability
