: Have to remember you need volume to make this work. Fresh water
: weights about 60 lbs. a cubic foot and sea water about 63 lbs.
: Subtract the weight of the materials used for floatation and
: you'll get the weight the floation will float. If it won't float
: the boat and you, there's no point in adding it in the first
: place, the frame will float itself just fine.

: For an average boat and average paddler, say 40 lb. boat and a 180
: lb. paddler you'll need something over 3 1/2 cubic feet of
: floatation. Takes more than a 4x8 sheet of that 1" foam to
: do it, more like 1 1/2 sheets and that's using all of the foam
: with no waste.

Hmmm you guys have me worrying now... It is really difficult to figure out how much foam I put in there, but there wasn't too much room left over in the boat for any more (except under the chines but there really isn't that much space available there either)... I'm not sure an airbag would get much more flotation than that... overall I would estimate there is about the same amount of flotation as if I had stuffed in 2-3 life vests. That may only be 30-45 lbs though then... is that going to help at all?
