After reading Matt Broze's article on survival rafts in Sea Kayaker Magazine's
book "Deep Trouble" I decided to get one.  Unlike Matt I had no trouble
finding one.
Fair Radio Sales  http://www.fairradio.com  has them in their catalog for
$59.50 plus postage.
After mine came I inflated it manualy and left it for a week with no signs
of leakage.
It folds up about the size of a Sears catalog and weighs only five pounds.
I plan to
keep it on the floor of my boat under my knees and attach a line from the
sea anchor
loop to a tab on my pfd via a quick release.  This way if I exit the boat
so does the
raft.  I will probably loosly wrap it in some foam for floatation when
uninflated.
I then have the option of inflating the raft to A. get out of the cold water,
B. use it as a super paddle float to re-enter and pump out my boat, C. use
it as a
life raft if my boat is blown away.  I can think of many other uses.

Question...  How does one rig up a CO2 cartridge to the inflation valve?
Inflating
by mouth is a bit slow.  It did not come with instructions and I don't know
the
military manual number. 
 
Even if I never need it (and I hope I don't) it makes a nice toy.
  
Hmmm... they even have the orange survival box kite.  Hook a strobe to it
and send it up
a few hundred feet at night.  Ought to attract some attention.

Have had about 30 years working with and testing water survival systems, and if this raft did not come equipped with a threaded bronze fitting for a cartridge and an inflation toggle --- along with specs for the cartridge --- it was not designed to inflate by a cartridge device, Gary.  There's no viable way to retrofit a cartridge to a orally inflatable raft, nor is there a safe way to figure out which size cartridge to install, anyway.  Without that, you have a neat water toy there --- not a survival system.  I wouldn't depend on it for serious rescue scenarios, from the sound of it, and I'd be really hesitant in connecting it to myself with a tether long enough to foul on anything else in the boat, as well.

Suggest testing it in real but controlled conditions, at the very least, Gary.  (You can't assume a raft will remain functional by inflating it to normal pressure and leaving it in a static state --- has to have the weight of your body in it and the dynamics of waves to really prove out its survivability.)
