How do you get the different parts of your hull to match up with each other?
I also tried to deal with shrinkwarp and solidify modifiers

until I found an EXCELLENT add-on
object_intersection.py written by our Polish Blender colleague - Witold Jaworski. You can find it here:

Witold is a strongly dedicated man. He has also written a complete blender manual for aircraft modelers (unfortunately still only in Polish although he plans to translate it into English):

I hope it is going to help you. Good luck with your attempts.

Of course still much work to do with it:
