Hull, fittings & equipment: 509 tons, 37.0 %
Fuel, ammunition & stores: 170 tons, 12.4 %
Miscellaneous weights: 50 tons, 3.6 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
430 lbs / 195 Kg = 8.6 x 5.0 " / 127 mm shells or 0.2 torpedoes
Stability (Unstable if below 1.00): 1.45
Metacentric height 1.3 ft / 0.4 m
Roll period: 9.8 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.11
Seaboat quality (Average = 1.00): 2.00
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.440
Length to Beam Ratio: 10.00 : 1
'Natural speed' for length: 16.43 kts
Power going to wave formation at top speed: 40 %
Trim (Max stability = 0, Max steadiness = 100): 35
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 15.00 ft / 4.57 m
- Forecastle (20 %): 10.00 ft / 3.05 m
- Mid (50 %): 10.00 ft / 3.05 m
- Quarterdeck (15 %): 10.00 ft / 3.05 m
- Stern: 10.00 ft / 3.05 m
- Average freeboard: 10.40 ft / 3.17 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 174.0 %
- Above water (accommodation/working, high = better): 78.5 %
Waterplane Area: 4,613 Square feet or 429 Square metres
Displacement factor (Displacement / loading): 92 %
Structure weight / hull surface area: 54 lbs/sq ft or 263 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.90
- Longitudinal: 2.43
- Overall: 1.00
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is cramped
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
A handy little ship!
Good for paroling in the Gulf- cheap, speedy and pretty simple.
I like it, DF... really like it.
Thankfully, that's not in the gulf.
*Makes note to add a lot of secondary guns to future ships*
I presume that she use sails too.
I like the concept of torpedo gunboat
Because torpedo boat concept in 1875-77 is really short, poor, delicate, breakable...
