Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
508 lbs / 230 Kg = 10.9 x 4.5 " / 115 mm shells or 0.3 torpedoes
Stability (Unstable if below 1.00): 1.10
Metacentric height 1.1 ft / 0.3 m
Roll period: 12.9 seconds
Steadiness - As gun platform (Average = 50 %): 50 %
- Recoil effect (Restricted arc if above 1.00): 0.63
Seaboat quality (Average = 1.00): 1.05
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.400
Length to Beam Ratio: 11.41 : 1
'Natural speed' for length: 21.86 kts
Power going to wave formation at top speed: 65 %
Trim (Max stability = 0, Max steadiness = 100): 48
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: 22.97 ft / 7.00 m
- Forecastle (20 %): 14.01 ft / 4.27 m
- Mid (50 %): 14.01 ft / 4.27 m
- Quarterdeck (15 %): 14.01 ft / 4.27 m
- Stern: 14.01 ft / 4.27 m
- Average freeboard: 14.73 ft / 4.49 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 170.9 %
- Above water (accommodation/working, high = better): 32.2 %
Waterplane Area: 7,459 Square feet or 693 Square metres
Displacement factor (Displacement / loading): 76 %
Structure weight / hull surface area: 36 lbs/sq ft or 175 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.51
- Longitudinal: 2.04
- Overall: 0.58
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is extremely poor
