Thanks for that Charlie.
I'm having to make certain assumptions, since the vessel was built for the Greek Navy, but all info I have is that they followed us in the main. Any contemporary photos I've seen, however, only show officers or ratings or, with the aid of a large magnifying glass, the whole crew.
I would have thought that, with a gunboat whose 11" gun was primarily used for shore bombardment, there would have been a greater ratio of Warrant Officers than normal in the crew and therefore on deck. Also, since the Ambrakia was built for sail (2 masts) as well as steam the crew numbers would have been higher, and more obvious, than for steam alone.
