Anyone knowledgeable about warships and naval history?

[Olumin]

I’m currently designing a fictional class of battleship. I would like some input regarding design improvements and overall feasibility of the design, however, I myself am not an expert. If you yourself are knowable about warship design and/or naval history, or perhaps know someone who is, I would appreciate hearing from you. You might be able to help me out. 

Furthermore, if you know some forum or website otherwise I could be looking into for advice, that would also be greatly appreciated. Thank you.

Perform a Google search for whatever on-line forums are talking about the "Springsharp" ship design simulator. Naval history enthusiasts use that tool to design fictional warships within the limits of a particular time period.

The people who rigorously or enthusiastically use it are found on forums where there is a wealth of knowledge on this subject.

The Paradox Interactive forums might also contain people like that.

And you can ask around on AlternateHistory.com
