They certified this ?? I am really surprized. I have to go back to our
classification society 
and tell them..  But I am not shure what my lead-acid batteries will do
with the crew 
if we roll over 180 degrees. But I have also a Diver hatch on the bottom
of the sub 
so it doesn't matter in which position the boat comes on the surface in
emergency case.. ;-)
