Krążownik kolonialny

Dzisiejszy okręt to mały krążownik pancernopokładowy, przeznaczony do służby w koloniach. Dwa okręty tego typu mają zastąpić stare korwety parowo-żaglowe pochodzące jeszcze z końca lat 50-tych XIX w. Jako że okręt jest mały, nie imponuje specjalnie swoimi charakterystykami, ale do służby kolonialnej powinien się nadać w sam raz:)

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      951 lbs / 432 Kg = 27,1 x 4,2 " / 107 mm shells or 0,4 torpedoes
    Stability (Unstable if below 1.00): 1,20
    Metacentric height 1,2 ft / 0,4 m
    Roll period: 11,7 seconds
    Steadiness    - As gun platform (Average = 50 %): 100 %
            - Recoil effect (Restricted arc if above 1.00): 0,43
    Seaboat quality  (Average = 1.00): 2,00

Hull form characteristics:
    Hull has rise forward of midbreak, raised quarterdeck
    Block coefficient: 0,541
    Length to Beam Ratio: 7,16 : 1
    'Natural speed' for length: 14,70 kts
    Power going to wave formation at top speed: 49 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): -8,00 degrees
    Stern overhang: 0,98 ft / 0,30 m
    Freeboard (% = measuring location as a percentage of overall length):
       - Stem:        14,99 ft / 4,57 m

       - Average freeboard:    12,47 ft / 3,80 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 117,8%
        - Above water (accommodation/working, high = better): 86,5%
    Waterplane Area: 4 378 Square feet or 407 Square metres
