Emphasis on armor and firepower.  Prefer fewer larger guns.

Maybe Chile is interested in a more Monitor style 'Juggernaut'?

Given how rough the seas are down along the southern end of Chile, I'd expect good seakeeping to be a requirement of the Chilean Navy, but I could be wrong too.

Given how rough the seas are down along the southern end of Chile, I'd expect good seakeeping to be a requirement of the Chilean Navy, but I could be wrong too.

Possible, but they didn't specify that.
Also small size plus big guns plus heavy armor plus high freeboard is an impossible combination.

An oversight on my part.  Nobody your design looked good, although a 14-15" belt would probably be sufficient, if there was any way to convert that extra strength into freeboard?  There may not be.

It would probably be similar to my previous entries.
But before I try, how much freeboard do you want? Or would you specify something else?

[Darman]

What would be a good sea-keeping?  1.20?  I was thinking about 1.15 for Chile.  If thats possible?

Damn, the brower ate my post...

If the value is above 1, SpringSharp gives no warning and at 1.2 and above it add the 'good seekeeping' message.

Well, still only 3m freeboard (just like my fist ship and only 50cm more than on the "monitor"), but this time its stable and the seekeeping is better. The price is about 800 tons as well as thinner armor and significantly smaller armored areas (end and upper belt can no longer be assumed safe against major guns).
I tried three and a half meters freeboard, but then you would end up with barely more than cruiser armor and a ridiculous slow ship.
Personally I think the "Juggernaut" would be much more fun. Maybe the Chilean would like to join the Congolese in their demonstration of the 35cm cannons?

Is there any way the Germans could replace the 350mm guns with 280/45 guns?  3 twins instead of 2 twins?  It would increase the volume of fire and be more competitive versus the newer classes of vessels currently being laid down. 
You can pare back the main belt down to 300mm if you need some additional tonnage.

It's a bit early for the 45s (otl wise at least).
Other than that, yes it is possible and I was able to increase the armor. However, it was better reworking the ship more extensively so it is actually stable:

I do have my doubts though, if you can fit 3 turrets and all smaller guns on a ship that is just 100 meter (~330 feet) long.
The engineers are scratching their heads though: What happened to "bigger but fewer guns"?

Given recent events in worldwide design, there appears to be a preponderance of designs with triple turrets.  The Chileans figured that triple turrets with slightly smaller guns but a faster rate of fire would allow them to throw more shells at an enemy. 

[Darman]

Lest there be any confusion, yes the Germans, previously awarded contracts for Chilean customs vessels, have been awarded the contract for Chile's first modern capital ship.

Possible elongated version to accommodate 3rd main turret in the center. I could make it 7200 tons as well, but then the armor would be unworthy its purpose.
