Designed to fight at longer ranges, therefore belt armor is sacrificed to thicken the deck and turret/barbettes. Secondary is designed to maximize anti-TB defense. 8.8cm AAA guns can fire at lower angles, but lack size to be of much use except against merchants, surfaced subs, or older TBs (200-500t). All armor is +10% 1915 Improved Krupps and the main belt is inclined 12.5* (25cm listed * 1.10 = 27.5cm actual). Main belt effective height is 12.01ft and Line-of-sight thickness is 28cm. (TL = TN/cos12.5*), 27.5/cos 12.5 = 28cm).

me thinks the belt is too short(in height) for a long fast ship.
Me thinks a 250mm belt is too thin.

4' above and 8' below is too short? How deep would be deep enough then?

280cm equivalent, and why would 250cm(280cm) be to thin? She's not going BB hunting and at longer ranges belt hits would be coming in at a downward angle, helping the inclined belt even more. What would be thick enough? 30cm, 32cm? I could thin the deck down to 100-110cm and see if I can get the belt up to 260-270 input (286-297 post 10% improvement, 293-304 effective thickness).
yes, 4 feet above and 8 below is too short. This thing is carrying 5944 tonnes of fuel, or in other words, 13% of the full load displacement is fuel. I have not the math to calculate the change in draft, but it's going to be pretty considerable. I don't remember what percentage of total bunkerage SS uses for normal displacment, but difference between deep and light is likely to be something like 3.8 feet.
I think a belt height of something more like 5m is required in a fast, long-legged ship of our era.

Divide the change in displacement (in long tons) by the waterplane area (in m2), and you get the change in draught (in m).
That gives me 1.2m difference between light and full load, or 3.9 feet (if I worked the calculator correctly).

The 2500t difference between the normal (SS2 assumption) and full displacement is what counts here. That's still about 1.5' draught.
