Krążownik szkolny

Dziś krążownik szkolny pomysłu kolegi JKS, któremu również zawdzięczamy rysunek. Starą korwetę Strzybóg, którą doraźnie przystosowałem do podobnej roli, chyba w końcu wyślę na złom (albo do kolonii:)) Uważnych czytelników bloga, którzy z pewnością zauważyli istnienie jednostki z 1819 r. o tej samej nazwie spieszę wyjaśnić, iż okrętowi temu zdarzył się przykry wypadek, otóż w 1896 r. we mgle wszedł na skały i na tyle się poturbował, iż naprawę uznano za nieopłacalną i okręt skreślono z listy jednostek floty. Tym samym zwolniła się nazwa dla nwoego krążownika szkolnego..

    Miscellaneous weights: 2 tons, 0,1%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      2 013 lbs / 913 Kg = 18,8 x 6,0 " / 152 mm shells or 0,6 torpedoes
    Stability (Unstable if below 1.00): 1,18
    Metacentric height 1,5 ft / 0,4 m
    Roll period: 12,5 seconds
    Steadiness    - As gun platform (Average = 50 %): 100 %
            - Recoil effect (Restricted arc if above 1.00): 0,78
    Seaboat quality  (Average = 1.00): 2,00

Hull form characteristics:
    Hull has raised forecastle
    Block coefficient: 0,486
    Length to Beam Ratio: 8,53 : 1
    'Natural speed' for length: 17,54 kts
    Power going to wave formation at top speed: 46 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): -20,00 degrees
    Stern overhang: 0,00 ft / 0,00 m
    Freeboard (% = measuring location as a percentage of overall length):
       - Stem:        18,96 ft / 5,78 m

    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 124,4%
        - Above water (accommodation/working, high = better): 99,6%
    Waterplane Area: 7 307 Square feet or 679 Square metres
    Displacement factor (Displacement / loading): 108%
