I am trying to choose between this large armored cruiser design and a semi-dreadnought battlecruiser design to determine the direction my heavy cruisers will go for 1905 and later. You can see both of the designs I am looking at in this post.

8 heavy guns in turrets is no-go, AFAIK. This applies to both ships.

Just 6 main guns in turrets max on all ships, but, you could increase secondary caliber

8 turreted main guns is legal as long as no more than 6 of them can bear on any point, so as long as these are wing turrets not en echelon. I think it's legal by the rules.

"centerline casemates" would be firing fore-and-aft, not to the sides, so first I doubt there's room for 14 of them, and I also doubt that that's how you want them arranged.

The same issue popped up with Walter's semi-dreadnoughts earlier and Carthaginian said that semi-dreadnoughts are legal, specifying that the limit applies only to main gun armament. You could have up to eight uniform guns on a ship in turrets and still be within the rules as long as they are divided between one fore, one aft, one starboard, and one port turret, if all of them are twins and the wing turrets are separated by the superstructure.

Walter

Quoteone fore, one aft, one starboard, and one port turret
Actually, you can have two port and two starboard turrets...
... as long as they only house one gun...
... unless you got a single forward and single aft, in which case they can be twins. :)

We are only allowed 999 tons or less for 1909, right?

If you want the ship completed at the start of the game, then yes. You will be allowed to continue to work on ships layed down pre-startup afterwards, but for bookkeeping reasons it may be easyer not to do so (my preferred choice).

Who cheer when solider lads march by
Sneak home and pray that you'll never know

Main belt does not fully cover magazines and engineering spaces
Bad. Very Bad.

Not as bad as you make it sound, Nobody. The belt is only a foot or so off... Probably because Delta Force used the default setting and missed the fact that that would not give complete coverage. It should be an easy fix.

I forgot to adjust the belt after editing some of the engine settings. It was only about a meter off. I had to bump the displacement up slightly but other than that and the armor changes it is the same:

KWorld

Solid smaller AC, with a better main battery than the historical vessels (4 x 24cm vs 4 x 21cm).  Speed may be a bit slow for AC service, though this will be more clear when compared against ships from your own continent.

Jefgte

I agree with KW, speed is a bit slow for an AC.

IMO
Choose 18kts for an EC or 21kts mini for an AC.
