Greetings shipbucketeers.
I understand the priority of the community is to draw more Real Designs to fill the archive, however, my first Real Design has proven to be a bit more...challenging than what I anticipated, mostly due to lack of sources, but I'll post that on the appropriate forum once you do a quality check on me!
In the meantime, I'd like to present you some fictional designs I've been working on.
The tabletop and videogame universe of Crimson Skies https://en.wikipedia.org/wiki/Crimson_Skies created by Jordan Weisman and Dave McCoy presents a universe where the United States is dismembered for totally believable and thorough reasons and gives way to a world dominated by gigantic airships (hooray!).
However, it totally disregards the fact that a world where the Washington treaty expires and London never comes around to happening has immense consequences to our dear and loved naval aspect of things.
So bla bla bla, goodbye treaty limitations, take a look at the Confederate States of America Ship, first of class, commerce raider Chickamauga!

Internal arrangement (based on Surrey sketches in John Jordan's Warships after Washington ) and blatant confession on all the bits I took here and there to make my life less miserable!

Camell Laird & Co. proposal for a commerce raiding cruiser of about 15000t.[/spoiler]
Just about everything else is greatly influenced by Hood's Surrey Mod, since both ships share a similar origin and timeframe, so thank you and please point out any crediting issues or nonconformities.
So please, do tell me what you think could be better, what you think is wrong and what is evidently wrong under any circumstances so maybe I can later go ahead and post this on the AU forums.
I appreciate your input.
