Miscellaneous weights: 25 tons, 5.0 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
1,164 lbs / 528 Kg = 10.2 x 6.1 " / 155 mm shells or 0.8 torpedoes
Stability (Unstable if below 1.00): 1.38
Metacentric height 1.2 ft / 0.4 m
Roll period: 10.1 seconds
Steadiness - As gun platform (Average = 50 %): 50 %
- Recoil effect (Restricted arc if above 1.00): 0.28
Seaboat quality (Average = 1.00): 1.83
Hull form characteristics:
Hull has raised forecastle
Block coefficient: 0.443
Length to Beam Ratio: 8.75 : 1
'Natural speed' for length: 15.15 kts
Power going to wave formation at top speed: 38 %
Trim (Max stability = 0, Max steadiness = 100): 27
Bow angle (Positive = bow angles forward): 5.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 16.40 ft / 5.00 m
- Forecastle (15 %): 16.40 ft / 5.00 m (8.20 ft / 2.50 m aft of break)
- Mid (50 %): 8.20 ft / 2.50 m
- Quarterdeck (15 %): 8.20 ft / 2.50 m
- Stern: 8.20 ft / 2.50 m
- Average freeboard: 9.43 ft / 2.88 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 70.2 %
- Above water (accommodation/working, high = better): 114.9 %
Waterplane Area: 3,823 Square feet or 355 Square metres
Displacement factor (Displacement / loading): 114 %
Structure weight / hull surface area: 38 lbs/sq ft or 186 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.92
- Longitudinal: 2.09
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is adequate
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
