			The saturated foam does not come just from standing water on the bottom of the bilge.  When I redid my V21 I had to do so because the wood under the deck was completely rotted.  No water was ever standing on that wood.  I was all because of humidity.  The PO never vented the bilge area after use or during the winter.  SO my thought is that if humidity is enough to rot wood it might be able to be absorbed into the foam in the same way.  Understand, this is just theory with no proof on my part.  If I was going to seal the foam in the voids I'd make sure that it was, indeed, a seal.  No weep holes, no top holes, no penetrations of any kind.  If there's no way for water to get in then there's no way for water to saturate the foam.
