Bezo, one class you forgot, and which actually did have the double row of casemates, was the Japanese Tsukuba Class, the class I sorta based my Artemis off.

[bezobrazov]

Fair enough. I did forget that class. However, the Tsukubas were not particularly successful. If you study photos of the ships, you'll notice the very low command of her 6"- guns. Also, it should be noted that it was only the positions fore and aft that received double casemates, not the entire battery. And, most of the time the lower casemate positions were left empty, with the casemate doors shut. (Though they probably leaked profusely). - Again, I would reiterate that if you absolutely need double-storied secondary batteries - and I'm not opposed to them - you need to do the following things: lengthen your ship some 15 meters and add a weather deck to bring the lowermost broadside positions up. Then it will become far more reasonable to have them!

[Zephyr]

Reasonable. I believe my primary motivation for this class is to be my navy's prime example of "what not to do in future ACR's", as in, this sounds like a good idea on paper but holy crap why did we build this??

[bezobrazov]

Hahaha! I can buy that! Good save mate!

Updated Orion Class, with a few modifications by Bezo

[Thiel]

Nice, but I can't help but notice that you've lost your propellers in the confusion.

[Zephyr]

We're manly men in the GHRN, we use oars! We don't need no stinking propellers.

The sailors got tired and threatened to mutiny, so props have been re-added and the correct image edited in.

With the data you gave I tried to sim her, having to totally guess at armor. She works but is a poor seaboat with a _very_ high recoil factor...
