Another interesting piece of software from Rick Robinson: "Spring Style" (warship design)

Rick Robinson has another DOS program written in C that you can download. It is doing general design of warships. You can download the source in C, so that you can actually see what he is doing (just like the Big Gun program). I experimented with it, and he is doing "quite a bit" (in some ways). He is going "easy" on armor weight calculations, but he is doing strength and stability calculations, so this is not some lightweight thing.
