How about a composite system where you use small empty bottles encapsulated
in 2-part foam? Originally I was thinking of a system like that using
ping-pong balls, but if cost is a factor the bottles would fill the space
much cheaper. I like the idea of ping-pong balls encapsulated in 2-part
foam, though. Kinda like REALLY big microspheres in epoxy. Might be worth
some experimentation.

You can also "enhance" regular non regulation foam with two part. Pour
a little two part in. When it is set up put some blocks of cheaper
foam in the area and pour more two part around it to seal it in. You
could also use the soda bottles in such a manner, I would poke some
holes in them though.

Here are my conclusions regarding that long thread I started about using
Ping Pong Balls for floatation..

Ping Pong balls are not cost effective. $20/144
PPB burn real nice.
PPB are relatively fragile.

2 Liter Soda Bottles are cost effective.
2 LSB can withstand the temp changes here in New England.
2 LSB looses volume quickly under external pressure. Designed mainly for
internal pressure.

Both will degrade in direct sunlight.

What will I do? More than likely I will fall in with everybody else and
use 2 part. I'll just have to make allowances for moisture to be able to
flow from bow to stern. With either of the other methods I would not
have to do this.

Thanks to all that posted.
