Yes, you're nuts. We all
are, so you're in the right place and I trust you'll feel right at
home!
:) Now to the
question. I'm afraid that idea is one that is proposed quite regularly
but doesn't hold water. You are correct in that water is almost
incompressible. But unfortunately it's still a fluid. From a structural
perspective it is as if it is not there at all, because it will transmit the
pressure from the outside hull to the inside hull yet will not resist it in any
way.
Double hulls in
submarines do exist, but they contain air and their purpose is to allow a
military sub to survive a hit from a torpedo.

ONe idea I have been tossing around is building a double hull around my
1atm
compartments.
The Idea here is to weld up say a 1/4 inch steel facetted hull, with
windows and all and then
build an outer hull of steel and acrylic with about a 1/4 inch space.
I would fill that space
with water and remove all air. To my way of thinking it would add strength
to the
over all hull as liquids will not compress.
My reasons for this thought are many, but mostly to use thinner steel and a
cheaper
way to increase outside viewing area.
Am I nuts?
Wait thats not the right question, for sure I am nuts but is it
feasable? The contents of this e-mail are intended for the named addressee only. It contains information that may be confidential.
