Miscellaneous weights: 63 tons, 34.8 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
89 lbs / 40 Kg = 363.9 x 0.8 " / 20 mm shells or 0.2 torpedoes
Stability (Unstable if below 1.00): 1.01
Metacentric height 0.4 ft / 0.1 m
Roll period: 12.2 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: 0.420
Length to Beam Ratio: 5.26 : 1
'Natural speed' for length: 9.92 kts
Power going to wave formation at top speed: 56 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 10.00 degrees
Stern overhang: 1.64 ft / 0.50 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): 101.3 %
- Above water (accommodation/working, high = better): 0.0 %
Waterplane Area: 1,148 Square feet or 107 Square metres
Displacement factor (Displacement / loading): 222 %
Structure weight / hull surface area: 67 lbs/sq ft or 327 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 3.19
- Longitudinal: 3.21
- Overall: 3.19
Hull space for machinery, storage, compartmentation is adequate
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
The external torpedoes are carried in tubes on the upper hull sides, facing forwards.
The external tube on each side can be replaced with a mine-laying tube, carrying 3 mines.
3 tons of the miscellaneous tonnage are for 2 reload torpedoes.
