Using bulges has its advantages and disadvantages, Hooman. If you add them, you gain HS, but at the cost of reducing the beam for all your stuff to fit. So don't forget to check if your main belt still covers the magazines and engineering spaces if you add the bulges and lengthen them when necessary. Also I noticed that by adding bulges, torpedo resistance goes down. So you can reduce armor, but I would keep the torpedo bulkhead as it is.
I would have to check at home if bulges have any other effect on the design.

Barbet armor always costs you a lot ... :o(

Don't forget to keep an eye on stability when increasing barbette thickness.

Another - minor - point is..... I don´t like bulges. :o/ Doesn´t look that elegant to me.... ;o)

I don't go for bulges myself because I think they are ugly. They reduce the amount of deck needed to armour, but then you have less space for your stuff to fit on.

Hooman, read the treaty again, you are unable to lay down replacements for ships until 1931. There was a 10 year no-building limit for all navies, but those with ships older than 1910 were able to lay 2 replacement hulls before 1931.

Aha so that is where the HS points are coming from. Looking at it now, that does seem logical.

Quoted

Was but not any more. If I am not mistaken, Nations that are not yet at their limit can lay down BBs before 1931 (like me). Also if you lose a BB, you can immediately start building a replacement before 1931 (like France)

Back to business again: Walter inspired me to work on my design again using bulges. RA raised a valid point too, as the CT in fact does not allow me to lay down any replacements before 1931. The two ships allowed because I retained vessels build before 1911 are OPHION and HYPERION. Anyway, below is the result of what I have now.

Modifications are

- change of date (1931)
- using adequate shell weights
- use of bulges
- increase in stability and of seakeeping
- increase in range (higher average speed)
- increase of barbet armor (now 380mm)
- deeper and thicker torpedo bulkhead (incresed underwater protection)
- increase of misc weight

Personally I think the design reached a point where it probably doesn´t make much sense to spend more time on it, trying to find another 10mm of armor somewhere or squeeze even more misc weight into her hull.

Thanks for your input.

You're suggesting that it is a submarine/battleship?! O_O

Either that or the artist has a very low opinion of their naval architecture! (sorry, misconstrued the picture as one of an Italian not SA warship.)

I'm more partial to Sun Tzu, who focus's on "the art of war" rather than just "art" or "form".
