I would suspect that the reasoning behind the shape is to keep it short enough to be repaired in colonial drydocks.  A couple posts ago Jef suggested that he was, at least for the moment, going to be limiting his protected cruisers to 120m in length, which isn't helpful at this time for speed.

KW is right

There are some issues with the design, though:

1 - It's lacking the upper belt armor needed to sim a protected cruiser.

2 - The 5.5" guns can't decide whether they're breech-loaders or quick-firing (should be breech-loaders).

3 - The 100mm guns should be quick-firers.

4 - Still not sure why the MN would be using a 7.6mm machinegun, the period French machine gun is the Hotchkiss Mle 1897, in 8x50R Lebel.

Work on this class is in progress...

I have an other option, the reuse of AT3 concept, actualy in France Shipyards, with more displacement, guns & protection.

Heh, well, with more displacement, guns, and protection, the AT3 might be OK.  :)  Won't be a lot left of the design, but that's OK.

arnt the belts kinda IDK Verticly challenged on that AC jef? id think you would want more than 2.4 meters on the main belt anyway, even if it is just a station ship.

OK, now, the upper belt is just 1 deck height : 2.4m & the main belt is now 3.00m height.
Finaly a better ship...

On ships like these, and other vessels that carry fuel, should we sim them using extra range or make use of the fact that SS3 already has the capability to sim below-decks cargo?  If you sim the fuel cargo as ship fuel, the ship's displacement is artificially low, compared to a ship designed to carry cargo or passengers.  This was neccessary with SS2, because it assumed cargo was on the deck, but SS3 doesn't make that assumption and allows you to place your cargo as needed.
