Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
52 887 lbs / 23 989 Kg = 38,5 x 14,0 " / 356 mm shells or 7,3 torpedoes
Stability (Unstable if below 1.00): 1,04
Metacentric height 5,8 ft / 1,8 m
Roll period: 18,2 seconds
Steadiness - As gun platform (Average = 50 %): 61 %
- Recoil effect (Restricted arc if above 1.00): 0,79
Seaboat quality (Average = 1.00): 1,22
Hull form characteristics:
Hull has raised forecastle, rise forward of midbreak
Block coefficient: 0,650
Length to Beam Ratio: 6,74 : 1
'Natural speed' for length: 26,60 kts
Power going to wave formation at top speed: 50 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 20,70 degrees
Stern overhang: -4,00 ft / -1,22 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 33,00 ft / 10,06 m
- Forecastle (20 %): 30,00 ft / 9,14 m (29,50 ft / 8,99 m aft of break)
- Mid (50 %): 27,50 ft / 8,38 m (19,50 ft / 5,94 m aft of break)
- Quarterdeck (15 %): 19,50 ft / 5,94 m
- Stern: 20,53 ft / 6,26 m
- Average freeboard: 24,62 ft / 7,50 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 93,4 %
- Above water (accommodation/working, high = better): 182,0 %
Waterplane Area: 56 903 Square feet or 5 286 Square metres
Displacement factor (Displacement / loading): 99 %
Structure weight / hull surface area: 201 lbs/sq ft or 982 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,97
- Longitudinal: 1,32
- Overall: 1,00
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Good seaboat, rides out heavy weather easily
I like the part where is says that the natural speed for the length is 26 kts, when that was my imagined top speed for the ship.
