I agree, ferro must be a possibility  and it should work in theory but it
could be hard to get certified. I guess that like in yacht hulls it has a
poor reputation and for a sub hull you can't afford to experiment. Certainly
it has merits in the way of cost and hull forms that could be made.

Good luck,

The US Navy did a bunch of research on concrete pressure vessels back in the 
60s. They abandoned it and turned to the metal ceramics that were ultimately 
developed and used with such success. I looked once before through my stuff 
but never located the picture I remember. Info should be available somewhere, 
if you were interested enough.
