With the look of the French ACs...

Nice looking ACR. I like the funnel layout.

I rework the drawing to place the 4 lateral turrets grouped in the middle of the ship, to have a kind of citadel disposition.

With this new disposition we could have 2 groups of stacks, fore & aft, similar to the old French ACs.

Jef

Ehh... I kinda prefer it the way it is now. I guess I never much liked the split funnel look.

The problem Brock is the internal disposition.
with the first drawing, boilers are around the magazines. Fresh water bunkers isolation are complicated.
If I group the disposition of the lateral turrets (citadel), boilers are really fore & aft, & the magazines in the middle.
Then, 2 fresh water bunkers are enough.

Jef

Modified with the engines room in the middle
, the boilers fore & aft with 2 group of stacks.
