I thought I would try a German fast battleship from a sketch I had done way back
I have a sketch of a large, German fast battleship (30 knots) that I did way back. This is a ship with 9-18in and 20-5in guns. I had hoped to be able to do that on 50,000 tons, but with Springsharp, I had to go to 65,728 tons, normal displacement, to get a good ship. I had to guess at dimensions, as I don't see any on the drawing, itself. The ship has a vaguely Italian look with two funnels and a tower foremast with bridge structure around it. There is a pole foremast and a low pole mainmast.
