Nowa kanonierka pancerna

Oto nowy okręt, kanonierka pancerna wzorowana na rosyjskiej Chrabryj, a jednocześnie rozwinięcie okrętu Hydra z 1888 r.: http://springsharp.blogspot.com/2014/03/kanonierka-pancerna.html

Wielkością, siłą ognia i opancerzeniem przewyższa nie tylko wszystkie dotychczasowe kanonierki, ale i wiele z naszych małych krążowników (mających po 1200-1500 ton), które z tego powodu chyba trzeba będzie rychło przeklasyfikować na kanonierki...

    Seaboat quality  (Average = 1.00): 2,00

Hull form characteristics:
    Hull has rise forward of midbreak, low quarterdeck
    Block coefficient: 0,533
    Length to Beam Ratio: 6,25 : 1
    'Natural speed' for length: 15,51 kts
