Niszczyciel z działami 102 mm

Czas pokazać kolejny, długo już zapowiadany okręt. Jest to wariant niszczyciela prezentowanego ostatnio (post z 12 kwietnia), wyposażony w działa kal. 102 mm. Z różnych względów, na tym kadłubie udało się zmieścić tylko 2 takie działa. Przewiduję, że kolejne typy niszczycieli będą już wyposażone w liczniejszą artylerię tego kalibru (3 działa minimum).

    Hull, fittings & equipment: 146 tons, 21,5%
    Fuel, ammunition & stores: 110 tons, 16,3%
    Miscellaneous weights: 0 tons, 0,0%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      131 lbs / 59 Kg = 4,0 x 4,0 " / 102 mm shells or 0,2 torpedoes
    Stability (Unstable if below 1.00): 1,67
    Metacentric height 1,4 ft / 0,4 m
    Roll period: 8,6 seconds
    Steadiness    - As gun platform (Average = 50 %): 40 %
            - Recoil effect (Restricted arc if above 1.00): 0,08
    Seaboat quality  (Average = 1.00): 0,64

Hull form characteristics:
    Hull has rise forward of midbreak
    Block coefficient: 0,478
    Length to Beam Ratio: 10,13 : 1
    'Natural speed' for length: 15,77 kts
    Power going to wave formation at top speed: 69 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): -10,00 degrees
    Stern overhang: 3,48 ft / 1,06 m
    Freeboard (% = measuring location as a percentage of overall length):
       - Stem:        14,96 ft / 4,56 m
       - Forecastle (20%):    13,48 ft / 4,11 m
       - Mid (30%):        13,48 ft / 4,11 m (7,97 ft / 2,43 m aft of break)
       - Quarterdeck (14%):    8,46 ft / 2,58 m
       - Stern:        10,43 ft / 3,18 m
       - Average freeboard:    10,11 ft / 3,08 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 206,2%
        - Above water (accommodation/working, high = better): 52,4%
    Waterplane Area: 3 986 Square feet or 370 Square metres
    Displacement factor (Displacement / loading): 20%
    Structure weight / hull surface area: 20 lbs/sq ft or 97 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,45
        - Longitudinal: 1,26
        - Overall: 0,50
    Hull space for machinery, storage, compartmentation is extremely poor
    Room for accommodation and workspaces is cramped
    Caution: Lacks seaworthiness - very limited seakeeping ability
