This is the 1914BB I'm laying down. She's not perfect, but w/ my limitations on slip size/total BP(Weight) and whatnot she's pretty decent if I do say so myself.

Pretty sturdy design. The freeboard's a little low for my liking, but it seems to work out for you. Certainly other folks work with similar freeboard.
Got a name for her?
Whaoooo
Nice drawing & very good general concept.
I note particulary the heavy protection - 40%
Jef ;)
Barbette protection is a bit problematic. For plunging shells, the upper belt does not defend the barbette - this is also true for the exposed part of the barbettes. Protection is almost the same as the Orange BBs. However:
Only the casemate turret mounts are armored, the casemates themselves are not. There's no armor between the mounts - I solve it by adding a few ft to UB height. Just compare the casemate armament armor weight to the weight of a belt that'd protect it, there's a big difference. Add ~3' to UB so that the guns would be armored.
Main external belt with 8' depth below waterline is a waste of steel. For external vertical belt below WL 6' should be enough IMHO.
Upper belt for Orange ships only covers the length where the casemates are located, perhaps the uptakes. I do not cover the barbettes themselves - but make barbette armor thicker.
So how does one handle casemate armor above the freeboard deck? You can't make the total of armored belts taller than freeboard, and the "other above deck" armor column for casemate batteries doesn't appear to do anything.
If SS2 screams of the high freeboard, increase thickness accordingly and make a note on it.
