The nice thing is that I can include Springsharp reports with documents

I can produce vastly superior documents about the Anglo-German Naval Race building program game, in that I have been generating Springsharp reports for them. I also have the ability to run my Warship General Design program on the designs. The advantage of my program is that I can generate pretty good power curves for a design. I believe Springsharp is using an empirical equation to compute SHP for a speed. For fast destroyers, it seems to be too inaccurate to be useful. Springsharp is generally superior in other ways, particularly with respect to strength calculations and seakeeping ability.
