If it's for a kayak or canoe you may look up sponsons.
Sponsons have become a nasty word in the kayak news groups because
there were some safety accusations made concerning their lack of use.
That or you could make something up with PVC pipe and end caps.
( The latter is great for Hiding guns in. (Water tight and tough should
you want to burry them : )).

I'm looking for something more about this size:

Maybe PVC would work...


I'd like to hear of what you might find (or what anyone might know about
pricing for 12"d pipe.) A quick calculation says that a 10 foot section
would be (roughly) good for 500 lbs at full submersion. A pair would be
good for 500 lbs at half submersion... I couldn't find the weight per foot
of the pipe itself. If it is cost effective, I could see a project or 2
that it would be perfect for.
