In Springsharp 3.0b2, the original concept for the Ger/BB/1905 works great

I had this idea for a rather fast German battleship, to be laid down in 1905, that would carry 8-12in/45 BLR and 12-4in QF guns. The speed was to be 23 knots, the armour basis 11in and the decks 3in+1in. In Springsharp 3.0b2 Beta, the ship works well. The original idea was to have a Standard Displacement of 22,000 tons. My design is 21,765 tons Standard. This is a photograph of one of the ships:
