I think I remember the product was called "Boat Saver" .... It didnt
work !!!! What happened is that on most boats, the hull to deck joint
is not designed structure-wise to contain pressure from the inside-out;
In all the cases of testing when the bag inflated when the boat was
submerged, the deck to hull joint failed, the joint was compromised,
the bag 'escaped' through the newly created hole in the joint, .... and
the boat sank anyway.

Subject: suggestions for emergency air bags to be deployed between watertight
bulkheads ?
From: Courtney Thomas

There was a company that made a system much like what you are describing.
Can't
recall the name off the top of my head. They are out of business as I recall.
Very costly and took up a lot of space.
I think they used CO2 as the inflating gas.

Of course, if your watertight bulkheads really are, why would you need it? :-)
