I seem to have found the formula for a good ship

My German battlecruiser design for 1911 really is good, if you don't mind all the guns forward (6-12in/50). I actually was able to give the ship 31 knots instead of the planned 30 knots. The armor is light, but what I had planned. The armor deck is 5in, so that helps the ship be well protected, along with the 2in A/T bulkhead. The deck is flush with a good freeboard. That always helps a ship.
