I need this explained simply: how does foam attached INSIDE the boat help flotation?

Once again we ignore the question posed by the OP. This isn't a discussion of the merits of types of flotation. It went off track after 6 posts and turned into a black hole of nothingness.

DumDum - If you other questions about flotation, please start another thread. Sorry about the potholes.

Closed.
