Intend to lay two of these ships down as replacements for the 20 years old Evertsen class, and as a bit of a tryout to see if i am in full compliance with the rules. Of, and for the fun of it as well. ;)

The range is the minimum required, it is enough range to go from the Dutch or Scottish bases to Kongo without refuelling.

The picure need some work, as it is my first attemt at drawing such early ships.

8x150mm guns are a bit few.

Also, please have an armor that is effectively half inches/12.5mm after you use the correcction for armor quality.

So if you want 200mm effective armor, you have to build it 210mm thick.
The first purpose of a warship is to remain afloat. Anon.

I corrected for the efficiency of my armour, but i have not bothered to try and make that number divide nicely with 12,5 as that was simply to much math for me, as sitting around going back and forth with a calculator several time for each armour plate on the ship was simply mindnumbingly boring.

An 8000 tons frigate? 

More like an armored cruiser...

IIRC JLDOGG was calling his armored cruisers armored frigates.

Probably using an older style of naming (Ships of the Line than Frigates, sloops, barks, etc...) or something like what the Americans were doing until 1975 when we changed our maning system yet again because we'd finally retired all the World War II build warships and thus could redefine what cruisers, destroyers, and frigates were in the fleet.

Posted some drawing of my older armoured frigates.

Feel free to comment.  :)

There is also drawing of my battleships in the http://www.navalism.org/index.php?topic=676.0 thread.

Finally got around to looking at your armored frigates, since they're getting involved in some confrontational situations.  Nice drawings - I like the old five-funnel one in particular, very period-appropriate.

Thanks! :)
de Zevern Provincien? She is maybe the most historic one, but my personal favourite is the ridiculously overgunned Flandern. :)
But I am not pleased with the look of my newest class, but then that is the drawing i made first.

Ahoj!
I'd be inclined to term this ship a "2nd rate battleship".

I think that could be used for most of my armoured frigates, as most of them carries at least 8 24cm guns, and fairly good armour. Speed is another matter...
So when more moden ships start entering service, they will be re-classified as 2nd rate battleships, or something similar. As with most Netherlands ships, firepower is the priority.

Hiya all

Korpen is right I did call my large(armored) cruisers frigates and the smaller protected type sloops and the ships between sloops and DDs were corvettes.

While I do not intend to do this at the moment, I played around with what a rebuild of Flandern would look like. The turbines and bunkers have been replaced on a ton-by-ton basis.
Guns and turrets would be repaired and upgraded to a slightly more powerful version.

The most intressting question is if it would be worth it.
