Kingdom costal defence ship.

[Korpen]

While unlikely to be built, I find it an interesting study none the less.
Her shallow draft makes her usefull in all kinds of shallow and congested seas, such as the North Sea and around the Indonesian archipelago; it makes her less suited to high seas work however.
The 12cm belt and 25mm deck gives her adequate to very good protection against guns carried by ships of equal size as well as ships quite allot larger.
I would have preferred larger main guns, but that would have pushed size over 5000 ton. Still, combined with her firecontrol (250ton) it should be enough to give ships three times as large a run for their money. In fact just her 8x12cm gun secondary broadside is in fact greater then many similar sized ships got in for main battery.

neither fish nor fowl... its too slow to run away from anything, can't threaten the newest DN's, wait too small to take punishment.  Its slow speed makes it a sitting target for subs and torpedo boats.  As said while IMing I think some of the NPC's might like it or something like it.

IMO, too slow.

If 5000t is your limit, Increase to 5000t for higher speed.
( test in 120m hull max...?...)

IMO, too slow.

Not for a defensive ship. If the enemy run away from her, superb; mission accomplished and the thing she is defending is safe. If the enemy still press on they are likely to be several times stronger, and a ship such as this at least got the potential to strike outside her weight class. A hit or two from her main guns are likely to cause significant damage to a CL, making trying to swarm her a very risky proposition.   

Also bear in mind that in allot of areas were ships such as this operate larger ships are often incapable of going much faster if they want to avoid the sandbanks and rocks on the bottom anyway.

The ship is also cheap enough to have a degree of expendability, something usefull in close to shore operation with mines, reefs, rocks and costal defences. Risking anchoring a 20kton dreadnought in area were there is risk for attack is stupid, but the huge increase in accuracy might motivate doing so with a 4,5kton ship.

If 5000t is your limit, Increase to 5000t for higher speed.
( test in 120m hull max...?...)

Increasing size by 11%, length by 10m and speed would result in a ship just 3kts faster, something that would not affect tactical function at all.

I'm with Korpen on this one. Sit her in a nice deep defensive minefield and in nice shallow water and she'd be a tough nut to crack, and could tie up the enemy for a good long time, hopefully until some nice fast Dutch frigates come along to help.

My main criticism is that I think she ought to be better protected, so she can take punishment longer.

Still, for high enough value targets, unsinkable heavy shore batteries might be a better buy for the money.
