This is the Ger/BB/1907, from the Blue Booi, with adjusted weights

This is the Ger/BB/1907 design, tweaked to try and achieve the weights from the original specification. This is a ship with 8-12in/50 and 12-4in QF guns, and a 13in armour basis. The originally specified speed was 24 knots. I had followed closely the armour plan from the sketch. With that plan, the 7,547 tons protection is too light. The protection in the Springsharp design comes out heavier. This is the tweaked Springsharp design:
