I don't know how to design ship
1. Get degree
2. ....?
3. Profit!
I'm still trying to work out what #2 is...
Define "design". If you try to add *some* detail then you will rapidly need to add *much* detail. That being said, I think there is scope for some general guidelines on producing feasible ship designs. With those, you can do it all in Excel. Or if you are ancient like me, you can always do it by hand...

I still haven't come near step 2
