[Sachmle]

Your casemates are all "on centerline, evenly spread" instead of "on sides, evenly spread" and you only armored your forecastle deck

- Armoured deck - multiple decks:
   For and Aft decks: 0,00" / 0 mm
   Forecastle: 3,00" / 76 mm  Quarter deck: 0,00" / 0 mm

Other than that, the only thing 'off' is the caliber the guns. Most guns were not 45cal in 1880. Examples to follow:

UK: 12"/25 Mark I and II (1882), 9.2"/26 Mark I and II (1881), 5"/25 BL Marks I, II, III, IV, and V (1875)
US: 8"/30 Marks 1 and 2 (1883), 6"/30, 35, and 40 Marks 1, 2, 3, 4, and 7 (1883)
RUS: 12"/30 Pattern 1877, 12"/35 Pattern 1886
Spain: 28cm/35 Model 1883

ledeper,

Again with the 45 caliber guns?
Chop them to a historic caliber, and you will save a lot of weight.

[Carthaginian]

Are you intentionally ignoring the fact that no nation on earth at the time had guns of that length?

[Tanthalas]

per lower the Caliber on the Guns mate, /35 and /45 is way to long for the period, You need 12/25, 8/30, and 6/30.  Might want to find an armored belt somewhere, as your last 2 Spring Sharp reports show no belts whatsoever.

[Tanthalas]

Looks good if a little heavy to me, what ship are you using for your baseline or is it just random? the BC feals high same with the forward freeboard, and for 1880 I think the minimum Composite is 1.10.  SS3 takes some geting used to, if you want ill take a stab at her see what I can do.

[Jefgte]

I agree with lenght/caliber-20/25/30 are more current for that period.

look at NAVWEAPONS

http://www.navweaps.com/Weapons/index_weapons.htm

No TBkh - the first TBs were built in 1875 with poor performances, so, 47 or 37mm guns were added vs early TB.

Your belt is idealy 100% , not 115%.

Add
Shells per gun, main battery: 80 to 100
Misc weight : 100 to 200t


Jef  ;)

[Sachmle]

I'm starting to wonder about the mixed 8" 6" battery. The 8" won't have a sufficient RoF advantage over the 12" nor a sufficient range advantage over the 6" to make them worthwhile, IMHO. I'd just go 12"/6" and maybe leave enough misc weight to allow the addition of some 47mm or 57mm Anti-TB guns later, if warranted (IC of course).
