First, thanks to everyone who weighed in on floation foam. sounds like
the blue sheet foam is what I need. It will be glued to under gunnels and
inside transom lockers, so expanding foam is ot an option.

Brian, Sounds like you did a lot of work. Thanks for sharing the process
and results. Blue foam it is, and a helluva lot less expensive then the
stuff I was finding.

Just one note - "Blue" is Dow foam; the "Pink" by Owens-Corning is very
similar in most respects The folks in Midland Michigan (Dow country) might
take issue. As I recall, Dow had a number of different blue foams, for
different applications. When I visited them some years back, they were even
developing a vermin/marine growth resistant formulation) Which you choose
depends on what lumberyard you frequent. There may be other brands, as well.
