I may bore people, but I want to rework old designs in Springsharp 3.0

I want to rework designs from our 1971 naval building program wargame in Springsharp 3.0. I wish that there were a more convenient way to display the freeboard diagram, as I really like that feature from the 3.0 Beta. Anyway, some of the ships I want to try are:

The Ger/BB/1905

The Ger/CB/1905

And the Ger/CB/1906

I also need to see if I can improve on these photos.
