SHHHHHHHHHHHHHHH!!!!!!!!!!
Its big that is sure.

One can only wonder how he managed to put that much armor, guns & misc weight inside that hull.
Low speed, long hull. It helps.
If I would do Brittanie on 20 kts, I will free up a lot of weight for armor.

My memory is that the USN carried similar - though not identically laid out - identification flashes during WW2, so I really doubt that having that mark to aim for will do much to improve the ease of actually hitting.
Or accomplishing much if they do.
I know of no American warship that had just a bright verital line on the middle of their hull. I know of many that used dazzle paint jobs at mutiple angles and shades of blue and grey, fails bows and bow waves painted on to confuse submarines of where the front of this ship was, the size and distance to or of the ship, and what speed it was going.
No, not on the side. But IIRC there was a practice of painting the tops of specific - and varying - turrets in different bright colors to ease identification from the air.
The top yes, but it is hard to hide from an airplane anyway. At this point in time, that won't be so much of a worry, since only the larger land based bomber can even carry a bomb big enough to really do much damage to a ship like this.
I was mostly thinking of the side of the vessel.
I think in the current placement of the secondaries interfere with main battery firing angles (that damn amidships turret). I'd have one of those pairs of mounts superfiring.
What's the machinery arrangement? Turbines and boilers both before and aft of Q turret?
Now nitpicking, feel free to ignore.
Your ship should be more "full" at the end with a 0.707 block coefficient, unlike the drawings. This means that the propellers will get a pretty unoptimized (bad) flow, so the ship might not be able to reach its design speed IRL.
It's hard for me to really tell about the secondaries, but as-is, there really isn't a perfect solution to be had, since there isn't any room to speak of on the islands, either. Not for a full-sized gun mount, anyway. Cross Mirage is simply a fairly crowded design and isn't going to stop being so no matter what I do. Even moving the midships barbette fore or aft and giving up its 'full rotation' ability won't solve that - it'd just free up room to breathe.
You're right about the machinery; The boilers are towards the midships, with the turbines 'endward' and a generator room past them, then finally bus rooms right up against the magazines for B and X. Boiler and turbine rooms are both subdivided laterally once, and there are two longitudinal bulkheads dividing the entire length of the area protected by the torpedo defense system.
So, a total of twelve boiler rooms, six high-pressure turbine rooms, six low-pressure turbine rooms, six generator rooms, and two bus rooms. In theory, steam from any boiler can go directly to any turbine by a minimum of two different routes, but while the insulation around the 'midships' steam piping is as good as could be expected, it's not perfect - so those only get used in battle damage drills or testing cycles. All six generators also have their own direct lines to both busses, which are, in turn, separately connected to the shaft motors.
Unless I forget to write it, you can expect a bit of news about the shake-down cruise's engineering staff burning the Head Designer in effigy, as one expects the overall system to be a stone bitch to work in and around... but it'll be priceless for damage control.
...I really can't make myself face redrawing the hull profile right now. Not after I already redid the upperworks.
If the Mods want to assess some kind of penalty for the recognition bands, they can go right ahead. Maori doctrine has it that the benefits to coordination and internal identification are worth it.
A slightly more obvious target, yet a slightly faster one - probably cancels out.
All because of some red paint...

But that white stripe subtracts from the overall movement.
it is a BEAST - I'm intrigued by the extra 900 tons barbette re-inforcement - how used + why needed?
- does this mean 'normal' designs without re-inforcement are sub-standard in some sense?
The barbettes are designed to accept guns substantially more powerful than the ones currently mounted; I'd consider anything up to 40cm/L60 as possible to see from the Maori in the future, with either a 900 or 1000 kg shell.

Then I'd just sim the ship as if with 40cm guns at the first place.
Which SS2 would take as meaning 40cm/L40, which'd weigh only, what, two thirds as much? Less, given differing construction and recoil issues?
SS2 doesn't pay attention to gun length only bore size.
