Ok, this has been robbing my every minute of sleep the past 2 nights, so I'm posting it before I go mental. The three Hydra class Battleships were built in 1885 and commisioned in 1889 and were at the time the best warships of eastern Mediterranean. They fought in the Greco-Turkish War (1897), in the Balkan wars of 1912-1913, and in the WWI. They served until 1929. There is a lot of info about them, Hydra and Spetsai were identical, where Psara had 3 masts somewhat different funnels. Their original paint of white hull and yellow superstructure changed later to the standart grey, which I might do, but first I have to draw Psara with the different upperworks. Here is more info of each ship:
