HMS Conqueror

Previously raised Admiralty plans featured a pair of new, revised Dreadnoughts, to be laid down in 1909. With the realisation that the original plan was unaffordable, and noting some slack in the Military budget of the Kingdom, the Navy opted to build a ship to a design more similar to that of the original Dreadnought type vessels
The Result of these revisions in HMS Conqueror, which possesses  a very similar hull to HMS Dreadnought, but despite having larger bulges still sits 2 feet lower in the water. The Design features a number of revisions including thicker armour, larger magazines, and a different calibre tertiary battery.

Bulges are not kosher - at least I hate them, myself, they are just a cheap way to save on deck armor.

Actually, the UNK having seen the effects of both mines and torpedo's on its warships opted to build the Dreadnought type Battleships, with Bulges. Another thing that pushed the idea was the successful use of primitive Norman designed Bulges on the French Battleship Greater Napoleon, to provide extra strength, something of great interest to the Battleship Designer.

Bulges are only know as a patch, a cheap and second rated way to camoflage a known problem.

Earl822

A problem like a known lack of strength.

Bulges do not provide much  extra strength. The only savings come from having a smaller armored deck area. Torpedo bulkhead is there for mine and torpedo defense. While bulges are just unarmored additions that will get flooded by a non-penetrating hit and start listing or even sinking without vital damage.

Therefore I accept that risk, if we all stick to the same rules, totally, all our ships will be identical. By using bulges the UNK accepts the risks of any flooding being made more serious.

Why would they not be ok? After all, pretty much ever French and Russian battleship had them, and (if going forward in time a bit) both Hood and R-class were designed with them.
The only real problem with excessive bulging is that the water plane decreases as the ship rolls, witch increase the risk of capsizing if suffering lots of flotation damage on one side in a short space of time.

And they do help protect the vitals of a ship against the effect of underwater damage, as space and distance is the only real defence against those threats.
