I am really finding "Springsharp" to be interesting and useful

Springsharp has inherited the Springstyle approach, but Springsharp is good enough and easy enough to use that I find that I can live with it, even though I would not choose to do it the way they do. What I do differently in my warship design program is that I don't freeze the displacement and start subtracting weight from the hull structure as features are added. Instead, I let the displacement increase as features are added, and show the results with respect to displacement, draft, speed, and stability.
