Not being a naval guy, I may be out of my league.
however, technically speaking, I wonder how effective this battleship was. It is essentially a motorized ship with conventional side pointing, muzzle loaded cannons ( with some turrets ), that is probably mostly wood but is armored plated. So it was probably very slow and maybe top heavy which is not a good thing in rough seas. However, if it is a river boat or shoreline ship, it may have been OK.
In addition, the sloping side armor at the waterline makes it easy to board the ship if it is swarmed by small row boats.
Anyway, looks like a magnificent ship. Full of character.
