Flota polska w XIX w. (cz. V)

W oczekiwaniu na upragniony pancernik - proponuję naprawdę solidną fregatę, o niebagatelnej jak na swoje rozmiary, sile ognia. 44 działom salwy burtowej dwóch takich fregat ówczesna flota pruska  nie bardzo miała by co przeciwstawić. A na pochylni (przepraszam, w okienku Painta;)) jest już rzeczony pancernik, więc przyszłość rysuje się w całkiem obiecujących barwach..

    Direct drive, 1 shaft, 2 122 ihp / 1 583 Kw = 12,70 kts
    Range 2 400nm at 7,00 kts
    Bunker at max displacement = 464 tons (100% coal)

Complement:
    341

Cost:
    £0,280 million / $1,120 million

Distribution of weights at normal displacement:
    Armament: 130 tons, 5,1%
    Machinery: 691 tons, 27,0%
    Hull, fittings & equipment: 1 091 tons, 42,6%
    Fuel, ammunition & stores: 434 tons, 17,0%
    Miscellaneous weights: 213 tons, 8,3%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      783 lbs / 355 Kg = 31,5 x 4,5 " / 115 mm shells or 0,3 torpedoes
    Stability (Unstable if below 1.00): 1,24
    Metacentric height 2,3 ft / 0,7 m
    Roll period: 12,7 seconds
    Steadiness    - As gun platform (Average = 50 %): 100 %
            - Recoil effect (Restricted arc if above 1.00): 0,49
    Seaboat quality  (Average = 1.00): 2,00

Hull form characteristics:
    Hull has raised quarterdeck
    Block coefficient: 0,541
    Length to Beam Ratio: 4,02 : 1
    'Natural speed' for length: 13,60 kts
    Power going to wave formation at top speed: 52 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): 41,00 degrees
    Stern overhang: 9,48 ft / 2,89 m
    Freeboard (% = measuring location as a percentage of overall length):
       - Stem:        16,47 ft / 5,02 m
       - Forecastle (19%):    14,96 ft / 4,56 m
       - Mid (50%):        14,47 ft / 4,41 m
       - Quarterdeck (15%):    16,47 ft / 5,02 m (14,96 ft / 4,56 m before break)
       - Stern:        16,47 ft / 5,02 m
       - Average freeboard:    15,13 ft / 4,61 m

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 136,9%
        - Above water (accommodation/working, high = better): 89,3%
    Waterplane Area: 5 701 Square feet or 530 Square metres
    Displacement factor (Displacement / loading): 96%
    Structure weight / hull surface area: 111 lbs/sq ft or 542 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,80
        - Longitudinal: 7,04
        - 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
