I'm not sure, however, what would my fleet use it for ....

[The Rock Doctor]

I think your powerplant needs to be trimmed back to 48,000 shp.

I agree it's good to have a use for things before they get built...

[Carthaginian]

Powerplant is above 48k SHP.
I think that the main belt warning will come back to haunt it.
If that could be fixed, it's not a bad ship.

[Borys]

Ahoj!
Thanks guys. Now fixed. The difference a single knot makes ....

[Carthaginian]

Biggest difference is in price...
Those last few tenths of a knot can raise the price by a dollar or more!

[Tanthalas]

looks kind of uhm farmiliar =P

[Borys]

Ahoj!
I shamelessly admt to using your hull dimensions as starting point.
She's not as good as I'd had liked, but a quite good AC nonetheless.
Borys

[Tanthalas]

check out the final production 10" in my post

[Borys]

Ahoj!
I have more armour cover, am faster, better stability.
You have better seakeeping* and minimally fire platform.

Comparable, tough to make a judgement.

* seakeeping is clculated for maximum speed, which is 2 knots higher in my case, possibly explaining the difference.
Borys

[Tanthalas]

 Mine will serve the purpose I intend for her quite nicely I think, Colonial Cruiser to be escorted by 2-3 Light Cruisers so for me Africa/Atlantic squadron(2 squadrons same composition) 2 of the 10" variant and 4-6 light cruisers.

[Borys]

Ahoj!
So you will use her as 2nd class Battleship? Fair enough.

Borys

[Tanthalas]

Essentially for the moment yes.  My light battle ship program just isn't working the way I would like it to, just not fast enough, or able to pack sufficient guns to be the impact type ship I'm looking for hence I decided on 2 smaller cheaper ships to do the job of one more powerful ship... for now

[Borys]

Ahoj!
IMO a quiet valid concept.

Ahoj!
Thanks guys. Now fixed. The difference a single knot makes ....

Not a bad ship by any count, as far as I can see she is optimized for destroying light and protected cruisers, she would be at best equal with older armoured cruisers.

[Borys]

Ahoj!
The question now is - build two Radetzkyy's, or five of the 5x6 inch 4600 ton cruisers?
