Not ugly enough.

A and Y are way too close to the ends, B and X should be superfiring to save space and move them more amidships.

The ugly comment I can support.

But the superfiring turrets. Not in this ship.Thanthalas is reworking her.

This better P3D?.
End On fire is reduced.  But lay out improved.


Thanks to Tanthalas, again.

Now is ungainly, lol.... Plus no longer kill admiral if Y turret fire directly aft
ADDED LATER:  Could do Truinfante side by side bow and make X and Q en echelon amidships.  Same # turrets and guns, better fire if chasing, less broadside though.

Ahoj!
I don't like the arrangment of either. I partly agree with Sachmle - Berta and Felix should be crossdecking, en echelon, amidships. Anton - alone fore, and Dora and Emil should be back to back aft.

B&D turrets will have horrible firing arcs, considering the spacing of the turrets i think that 90-100 degrees on each beam is the best that can be hoped for.

And i think the ship is over-armoured; there are no guns in existence that motivates that much armour. If (unlikely considering the tech of the day) the plate offer full protection for its thickness, it will stop a 38cm AP shell at around 20hm, and smaller shells at even shorter range.
It would be possible to reduce the main belt with 10%, and not suffer any real loss in protection, the saved weight could be used to make the belt deeper.

Go with the first version, Maddox.

So it's a bit cramped, and the turret placement for 1 & 5 are as close to the ends as some pre-dreads. If there is technically enough room for engines, then I'd say 'build it like that.'
I LIKE the lack of superfiring- it gives the ship character. It's not trying to be an uber-ship... just the biggest of the big, fitting right in with France's general desige to be 'Glorious' in all ways.

Sometimes, designing the BEST ship gets confused with designing the PERFECT one.

Actualy, there seems to be a matter of size/perspective. 
All the 6 centerline turreted ships I have found- albeit superfiring- weren't as long as the DeCreme with its 220m. 
They got all 6 turrets on, and with a larger superstructure than this Glorious design.

Even Agincourt achived 7 turrets in a useable lay out.

************************************************************************************
In the end, I think it will be a combination of the 2 drawings. 

Fun idea
Side profile 2 smokestacks, but in effect having 4, with 2 side by side stacks (like the Majestics)

The limiting factor is not the length of the ship, it is the length of the belt, as it is taken for granted that you want all the main gun inside the main belt. Superfiring will save at least 20-30m of belt.

She also had a belt covering around 75% of her waterline lenght.

And it was still to short. The belt only continues to the middle of the barbette of Sunday turret.  Also, she has to superfiring turrets, if they were all on deck the belt would have to cover the whole damn ship

Korpen... bluntly, what if he DOESN'T WANT to save that weight?
I mean, he's designed a good ship, and the art isn't actually to scale. Lots of room for error as to whether or not the drawing there is actually giving you a good impression as to what it looks like. SS might not be perfect, but it asumes that the turrets will fit; if it's good enough that way, it's good enough for the game, I guess.

If we knew the EXACT length of, asy, the British 15" turret, we could see if this would fit.
Anyone here know that or have a site we can use to find it?
