Flota polska w XIX w. - kolejne kanonierki

W nawiązaniu do poprzedniego postu dziś prezentuje okręt, mający być szybszą wersją małej kanonierki. Jak widać efekty nie są jakieś specjalnie porażające – przy ówczesnym poziomie technologicznym (który jest przez algorytm springsharpa uwzględniany) nie da się zbudować specjalnie szybszej jednostki o tak małych rozmiarach jak kanonierka z poprzedniego posta. Stąd też wariant drugi – który wobec niemożności zbudowania okrętu szybkiego ma przynajmniej cięższe działo. Obydwa projekty uważam jednak za nie stanowiące nowej jakości wobec poprzedniego typu, stąd są tylko w pojedynczych egzemplarzach..

    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 162,5%
        - Above water (accommodation/working, high = better): 50,8%
    Waterplane Area: 1 413 Square feet or 131 Square metres
    Displacement factor (Displacement / loading): 79%
    Structure weight / hull surface area: 40 lbs/sq ft or 196 Kg/sq metre
