I have no doubt that I've gotten at least one thing off and/or unreasonable, and am counting on my kind new neighbors to point them out for correction. ^_^

[Tanthalas]

only thing that realy jumps out at me right off the bat is the lack of an upper belt, other than that without knowing your tech status id say looked good 18 knots is a tad slow but you realy dont have anywhere to go so it should be fine.

[Borys]

Ahoj!
Lack of Upper Belt apart, why the raised poop deck? For a bigger splash?
Hurr-hurr?
Borys

[Valles]

Very early in the progress of my attempt to produce an image of her, but it should give a clear idea of why her freeboard looks that way.

[Borys]

Ahoj!
The Big Splash is now understood.
Tough to sim.
And I think that the twin MG turrets should be "raised" - I could be wrong, though.
Borys

[The Rock Doctor]

Cool.  I disagree with the main turrets - if anything, I'd put the singletons below the deck, if SS allows it.

Your operating range is really short, and your deck armor quite heavy; maybe increase the former at the expense of the latter?

[Borys]

Ahoj!
Good point on the deck - 2 inches is OK. 3 inches - immpressive and/or wasteful at this time.

SS does not allow turrets below freeboard.

Dreadnaught's fore turret is "raised", the wing turrets are "on deck".

now im the one that feals stupid lol I have spent forever trying to come up with a way to do just that in SS

Revised version! Elevated main turrets, upper belt added, tweaked deck armor. Lesser stability but it's not like she didn't have it to spare. Top speed is limited by the age of her machinery - 20,000 hp will only push a ship this size so fast. Range is not considered a priority; her reason for existence is to smash intruders, not to go overseas looking for trouble, and the legs she's got are plenty long enough for that.

[Tanthalas]

Looks like a good BB for a mostly reclusive culture, Im eager to see a pic of her ^.^

[Valles]

Updated with GUNS! ^_^

[Tanthalas]

you might want to make the guns a tad taller.   unless of course your People are Pigmis (only Pacific Islanders I have ever known were Samoans, and they wouldnt even fit in the palatial french turrets =P)

[P3D]

1902 steam turbines are worse than VTEs of same year.

Ship is just insanely large. Too high freeboard. About a thousand ton wasted on that alone. Length is excessive for such a mediocre speed. The armament and armor would fit nicely on a 18000t ship of 150m length.

Turrets usually had entrance in the 'bustle' floor, and they were raised above the deck by ~1.5m. If not, you must have a door at the back face with weak armor. AFAIK no navy choose that option. And turrets height should be ~3m.

Turret side armor is thin.

Quarternary armor for the 75mm guns... 6"??

Range is unacceptable. Even the KuK Marine, confined to the Adriatic, had longer ranged ships.

[Valles]

With potential homeports on the order of 6o degrees south latitude, I kinda can't see any seakeeping measure being excessive.

Turrets usually had entrance in the 'bustle' floor, and they were raised above the deck by ~1.5m. If not, you must have a door at the back face with weak armor. AFAIK no navy choose that option. And turrets height should be ~3m.

I've yet to be able to find a detailed enough depiction of turrets of the period to properly gauge their dimensions; these are guided by what I understand must happen within them... and tank turrets. The turret's machinery, in my mind, extends down into the barbette in a rotating 'cage' that hangs from the rollers around the edge. Crew access is by ladder, either from above or below.

Range is unacceptable. Even the KuK Marine, confined to the Adriatic, had longer ranged ships.

Unwise, I'm prepared to say that it may well be. But given a design mandate of 'local' defense and the availability of resupply by train anywhere along the defended coast, I think that 3000 nm is quite adequate.

I'd very much rather avoid scrapping my existing visual work for this class, also. After all, I have to do all this in MSPaint, so it's kind of labor intensive.

[P3D]

Turret access from above means large holes on the very thick (6-8") turret roof. Below access is problematic, as the barbette is a closed cylinder, and your solution would offer entrance/exit only through the magazines. Forget leaving the turrets in any kind of hurry.

And here's what I managed to get on 17000t.
