Reply Nice design....
--------------------------------------------------------------------------------
..but some nitpicking:

Your turrets are very well protected while your belt doesn´t fully protect your magazins. Is this a good idea?

Your CT will not protect your commanding officers from heavy shells. So isn´t it a waste of weight?

I noticed with springstyle that sometimes a certain percentage of main belt would cover the same ammount assigned to machinery and magazines and other times it wouldn't. Here with springsharp you notice that the 85% won't cover the 85.7% machinery and magazines space. It wouldn't surprise me that with springstyle it would have been 86 % and you would be able to cover it with 86% belt.

Good ship, not bad armament/speed on the tonnage.

Lose the upper belt though, and add it to the conning tower, main belt & deck. As it is, it's a good deal of weight, but won't stop anything big.

Holy...
That is a bit of a problem. Looking at the historical Kaga it went down from the designed BB displacement of 39,900 tons to 28,000 tons. That's a good 11,000 tons off (What the hell did they throw of that BB ??). So if we were to utilize that, it'll mean you'll get to 36,000 tons and you'll be 3,000 tons over. Even if we were to allow a window of 2% to cheat, you'll still be 2400 tons over.
Perhaps you should design it a bit smaller.

Heres the carrier version, I added 7200 tons for michelanious weight and removed the upper belt, armored ends, main guns, CT armor and reduced the belt to 4 inchs. My big problem is the fact that I am basing these ships on models I plan to build, ironically on HMS Hood hulls that i have so the dementions can change only slightly. The funny thing is the dementions are not much larger than the Nagato but she comes out heavier,shes a behemuth!

Well, if you were to remove the turrets and the barbettes, remove upper belt armor and ends armor, shave 7 inches off the main belt this ship will lie higher in the water. Also for both the BB version as the CV you have quite some hull strength left.
Are the models waterline models ? If that is the case you can change depth of the ship more than the length and beam and of course you could adjust the block coefficient. But be carefull, changing these aspects could be tricky and something might drop below 1.00 pretty fast.
If you want it, you could also change your machinery so that it'll go slower but you'll free up some more weight.

BB
Armament: 1,530 tons, 3.0 %
Armour: 13,838 tons, 27.4 %

CV
Armament: 97 tons, 0.2 %
Armour: 6,431 tons, 12.7 %

You loose 1433 tons from the armament and 7407 tons to the armor. Total 8,840 tons.
This change will decrease your draft to about 27 feet (warning: this is a manual calculation and not done with springstyle)
While the planes may add more weight, you might stick to such a depth and kick some of that "Hull, fittings & equipment" stuff off (at least some of the fittings and equipment part). It's good for half the weight of the ship.

This is one way of doing it. The only things I changed are speed (decreased to 30 knots) and radius (increased to a lot). Without changing anything else on the ship (except a .3 ft increase in freeboard) and without dropping speed below 30 knots, this could be as close to 33000 tons as you can get...

However it has a range to sail from Atlantis to South Africa to India to Japan to Australia to Hawaii to the Panama Canal to New York to Nordmark to Germany to GB to Iberia to Italy and back to Atlantis without having to stop to refuel !

Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1.29
Shellfire needed to sink: 59,173 lbs / 26,840 Kg = 547.9 x 6 " / 152 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 6.8
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 67 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0.02
Relative quality as seaboat: 1.39

Hull form characteristics:
Block coefficient: 0.653
Sharpness coefficient: 0.41
Hull speed coefficient 'M': 7.27
'Natural speed' for length: 28.81 kts
Power going to wave formation at top speed: 54 %
Trim: 48
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)

Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 93.2 %
Relative accommodation and working space: 245.2 %
(Average = 100%)
Displacement factor: 151 %
(Displacement relative to loading factors)

On a carrier ?!?!?! [/quote]

Whoops !!
That's there because I accidentally hit "1" when asked if the secondaries are above the main deck. It'll convert the "1" to "no". Too hasty with the design.
