the outer hull the thicker hull and use that as the pressure hull but that
forces the issue of pumping out the water if I want to use it as a ballast. If
not then it would be better to give the outer hull the thicker hull and use
the supports holding the inner hull for reinforcing beams for the outer.
Having the inner hull as the pressure hull also allows me the luxury of a
safety shell before anything makes it to the inner main pressure hull. 
 
     Any thoughts from anyone? So many things to consider...
