Armour disposition and torpedo defense system for BB11-12

You have to sim it with a bulge narrower than the waterline - and that'd leave you no TDS to speak of.

Why? The slope of the hull could just as well imply a low block coefficient.

However I do think that it would be much better to have the hull go straight down from the bottom of the belt rather then continue the inclination of the belt.
Also, I think the 15-degrees inclination of an external belt look very strange, and would recommend at last making the upper belt vertical to reduce the overhang. Given the shape of the hull as illustrated the seakeeping of the ship would be severely affected due to the high topweight and overhang.

That might be, but the BC is 0.637.
Also, broad beam helps stability and underwater volume - with the shear extending down below the WL you won't have either.
And in a fast ship you'd need the underwater volume.

The big disadvantage of a hull sloping like that is that the deck becomes a lot wider than the beam on the waterline.

A wide deck means a lot of weight in deck armor.
