There is an interesting page about Dutch battleships considered prior to WWI

While I was looking to see if I could find anything about the Dutch navy during 1890-1910, I found this page, which tells about the ships that the Dutch considered building. The idea was to replace the older coast defense battleships with more potent designs. The page is titled: Road to Strength: Battleshipplan 1912. There is data and drawings. The Dreadnought-style design from Krupp-Germania (Project 743) is particularly interesting. The ship was to carry 8-13.5in and 12-5.9in guns. The speed was 22 knots. The displacement was to be 21,300 tons. The belt was a maximum of 250mm. There is only the drawing and no dimensions, but tried to estimate the size. This is a Springsharp report for what I tried:
