Jim these plastic pontoons look like they for sure will do the job.
I will have to get some pricing on them.
I had thought of the propane tanks as a solution, but do not know
what the condition of
a scraped tank might be and welding them together might be a
problem. I think I am
looking at about the 12,000 lb displacement
numbers.

Dean, For pontoons for a floating drydock, you might check with
propane distributors for junk tanks. One 250 gal. size is 30" in
diameter, 8' long, and has about 2,000 lbs. displacement. Some of our
central California yards are bulging at the seams with junk tanks. There
are segmented rotomolded plastic
pontoons: http://www.plasticpontoon.com/ Jim
