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.

The home improvent stores around here sell regular and high density. I'd
use the regular. It's cheaper and lighter so it has more floatation. The
higher density board is stronger, heavier, and costs more.
