Flota polska w XIX w. (cz. I)

No to startujemy z okrętami dla naszej floty;) Na początek skromnie: pierwszym okrętem będzie żaglowy bryg z drugiej ręki, mający służyć jako okręt szkolny, stąd nazywający się oczywiście Gryf:)

Kolejne jednostki to dwie kanonierki parowo-żaglowe, o nazwach – by pozostać w konwencji mitologicznej – Pegaz i Meduza.

Wreszcie – dwa małe bocznokołowce, jakich pełno było w ówczesnych flotach. Sklasyfikowałem je jako pomocnicze kanonierki, ale to w zasadzie uzbrojone statki cywilne, przeznaczone do różnych drugorzędnych zadań (służba patrolowa, dozorowa, łącznikowa itp.).
