Bear with me for a second.

I have been hearing about people using ping pong balls for floatation.
However, I can't find anyone who has actually done it.

It makes sense in that it will allow water to flow and not trap water in
the bilge. They should last a while and certainly easy to install.

Anyone have any first hand knowledge of doing this?

We had a rather long discussion about a year ago, do a google search.
I think the general concencus was that there are much better, cheaper,
safer, etc.. ways to do this. The "Safety standards for backyard boat
builders":

gives you a good starting place.
