Miscellaneous weights: 150 tons, 24.0%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
1,578 lbs / 716 Kg = 188.2 x 2.6 " / 65 mm shells or 0.8 torpedoes
Stability (Unstable if below 1.00): 1.15
Metacentric height 1.0 ft / 0.3 m
Roll period: 12.0 seconds
Steadiness - As gun platform (Average = 50 %): 52 %
- Recoil effect (Restricted arc if above 1.00): 0.03
Seaboat quality (Average = 1.00): 1.04
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.700
Length to Beam Ratio: 9.29 : 1
'Natural speed' for length: 18.16 kts
Power going to wave formation at top speed: 52 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 10.00 degrees
Stern overhang: 10.00 ft / 3.05 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 15.00 ft / 4.57 m
- Forecastle (20%): 9.50 ft / 2.90 m
- Mid (50%): 9.50 ft / 2.90 m
- Quarterdeck (15%): 9.50 ft / 2.90 m
- Stern: 9.50 ft / 2.90 m
- Average freeboard: 9.94 ft / 3.03 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 76.9%
- Above water (accommodation/working, high = better): 177.8%
Waterplane Area: 6,093 Square feet or 566 Square metres
Displacement factor (Displacement / loading): 157%
Structure weight / hull surface area: 34 lbs/sq ft or 167 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.97
- Longitudinal: 1.26
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
