Well, yes, this is true, but an industrial fiberglass pipe is likely to be
very heavy and quite costly. A sonotube is cheap, or perhaps even free. Cut
one in half, you have two round bottom outrigger floats.

Look out! Look out! <grin>. You do have to "core" the PVC tubes with
something or they are too limp. I've wondered about using the spray-can
polyurethane foam insulation and letting it fill the PVC up.
