How about another cheap and lazy suggestion? During the summer you can get
swimming air mattresses at the local Walmart for $1.50. If they are well
protected against punctures, that sounds like a winner to me.
Unfortunately, I'm still searching for hardware to lash stuff in .... If
you've got that figured out, let me know!!!

good luck!

I'm looking for options to flotation bags for a plastic boat.

Will the heat generated by pourable two-part flotation foam damage a
plastic
boat?

What are the advantages/disadvantages to carving a block of minicell to
fit
the boat.
