...oh, yes, and:
i]Warrior[/i] and Matador are follow-ups to the armored cruiser Luchador.  Apart from improved horizontal protection and speed, they are also designed to incorporate centralized fire control and an experimental Huelsmeyer device.

Warrior, laid down 1911 (Engine 1912)
Tricky ship to evaluate:
Her protection is very good for s hip of her type, maybe even a bit over the top.
Her speed is what can be expected of a ship like her, more would be nice, less would be useless.
Her firepower is adequate, but not impressive.
In short she is a very solid ship. While unimpressive in any single aspect, she have a solid balance; i think i would consider her as a baseline ship for comparison among ships of her class. :)

Since other folks have already built 12" BCs, I think it's logical for GC to design its BCs to be armored against 12" fire.

35 cm guns were an option, but I'd either end up with six guns or a larger, more expensive vessel.  I decided the 12" compromise was, on the whole, better in this case.

I could get up to 27.5 knots by shaving down the deck armor, but reckoned the additional armor was more important.

Overall, a "solid" ship is fine with me!

Valles

I don't think I'd call her a battlecruiser at all; she lacks the foolish fragility that's the defining trait of the type. A good fast battleship on less tonnage than I'd've believed possible, and pretty besides. Well done.

Thanks.  She's actually a bit more pretty and modern-looking than I want, but I'll take it.  If I'd had room for five funnels, I'd probably had done that.

Sorry, I spoke out of place there - Gran Colombia thinks of these as armored cruisers, as they're defined.  More a historical German-style BC than a historical British-style BC.

Korpen

Gran Colombia might be looking for a more pious design:
The four turrets atop the chapels are to be named for the four apostles. The three engine plants and funnels are a reminder of the holy trinity. The ten 14cm guns in the hull is a symbol of the ten commandments.
Compared to a more conventional design the ship have less firepower on the broadside, but more over the stern and bow. The main battery is arranged four abreast in two levels.

That's almost too cool for words.  Just shooting at such a ship would be blasphemous.

Korpen,

I'd get some extra armor on the casemates, you have like only 4m length armored for each big gun.

Which of the casemettes? And explain further what you mean? As if i am not mistaken, the transerse bulkheads is the ones most affecting the gun.
Strictly speaking, i think all of the big guns are above the belts...

I see i had forgotten to draw in the casemettes in the hull, nor have i put any real effort in calculating how high the belts should be (as it is i think the upper belt is longer then the raised freebord, scale of drawing is 1pixel = ~25cm).

If you convince yor enemy that, she is a sure winner! :)
At least as longs as they are not heritics, heathern or balsphmours... :)

I just calculated how much coverage that 300mm armor would be over the main battery - not enough IMO.
I'd move two guns on each level a bit forward-Aft so they'd be able to fire abeam. Only if you want to bother with the design, ofc. ;)

Hm, that list includes about three times the BP GC currently has.

Well, I assume that's why this ship is armed and armored.

...for now.  Soon it'll get better.  Or worse.

I didn't appreciate that this was a battlecruiser, rather than a battleship. 

Now the question is how this might be afforded...

Hello,

Now that is an 'inspired' design(sorry couldn't help it)  ;D

We need an award for most creative warship, that is just awesome. Reminds me of Warhammer. Thanks for the presentation.
