We may know that torpedoes are somewhat over-valued at this time, but our respective nations may not have an accurate grasp of their capabilities.  You'd probably get a faction in your navy that wrote them off as wastes of space, and another faction that couldn't get enough of them.  Your design philosophy would depend upon which faction controlled the decision-making process.

Thinking out loud, those 12" fixed guns might be better simmed as a quad turret with no side/top armor.  That'll give you the loading machinery and associated weight.  Alternately, maybe an open turret with barbette or something?

khymerion

Well... I don't get the joy of having quad turret anything and most likely would get chewed on for even thinking it.  I also want the afford the crews maximum protection considering the insane job this would bring them and I don't have the technology nor the superior guns and mounts to do anything more impressive.  While I would love to have an open barbette, that doesn't exactly scream protection, considering the wall of lead that will be pitched at them during the final closing moments that the ship will experience.  I know I should refine it more but having to play within the very very hard rules means I gotta cut some corners somewhere... wish there was a way to just put the mechanisms that go into a turrent and make them work on the large scale for the forward castemated 12" guns.

Then add some miscellaneous weight to represent it.  Unfortunately, I can't tell you how much to add...

One solution is to forgo all deck armor, and only armor the ends ,upper belt and front of the turrets. But to avoid golden twinkies, the barbettes as well
The close range this ship will fight won't allow for deck penetration.

Maybe no deck hits as such, but you still want some deck protection to stop splinter and force from shells that penetrate the belts or detonate above them from reaching the magazines and engineering spaces.

This monster has only 8 305 mm guns, all bearing the forward arc.
400mm armor for the ends and upper belt, and yes, even a bit of deck armor.
The  large battery of 152mm guns will cause havoc and soft kills alls over
The 10 casemated 104's are an aftertought to have at least an token effort agains enemy torpedo attacks.



And it's cheaper...

The main problem will be when you are passing through the battleline (assuming it suvives the approach), at that range the ships on either of your broadsides will have a nice ship of your profile at point blank range (might be too close for main battery hits on the main belt, but I don't know that for sure...though it would be their end on fire verses you broadsides then).  The Samwise with 6 inch secondaries should be able to rip into their end armor at that range (the 4.5 inch might even be able to do that on some ships at less than 1,000 yards), and if you could split fire your main batteries you'd have five guns per braodside.  With the French more normal twin turrets you'd have four guns per broadside, which should outgun or equal most ships end on fire.

You cannot armor your ship to the extent that it would be invulnerable to point-blank shots.

Ithekro

True, but also if you are charging a line of battleships with only a few of these, the ships at the end or there cruiser support can pull off and engage you on the broadside at range, at which point the French ship's thin 4" main belt could prove to be a problem.

khymerion

Well... now that I have heard all of these ideas, I would have to say it is a novel idea but till better guns are developed (and thus removing the need for such a ship)... this project will be relished on the "it will look good in a pulp fiction book" category of material, next to Mr. Vern's or Mr. Wells' recent books.

It will be counted among such unfeasible inventions like submarines and heavier-than-air aircrafts.
