Judy:
Wouldn't it be better to have something that wicks condensation and lets it
evaporate rather than someting slick like closed cell foam? The headliner
(carpet) is excellent for wicking and evaporating moisture. Closed cell foam
allows moisture to run and collect. The wicking material should have a low
affinity for water (allow it to evaporate easily). Such materials are
polypropelene and other plastics in a strand or filament like structure.
Wool has a higher affinity for water than the synthetics. As for the nuts
and bolts gouging into your skulls I would recommend wearing bicycle
helmets. They work anywhere (even on the boom) and provide additional
flotation, plus they are aerodynamic.

>I am in the midst of putting 1" thick closed cell foam on the cabin ceiling
on my P19. I need to, because I've put a zillion bolts thru the cabintop
and I need to protect the tops of our heads from getting gashed on the nuts.
I'll install the new carpet headliner over the foam.

>For the area under the regular headliner, that adds up to about 5 cubic
feet of flotation. Eventually, I plan to line the whole underside of the
deck to reduce condensation inside the boat when we sleep on board.
Eventually, it will add up to probably 7-10 cubic feet.

>That's really good placement for the foam, very high up. It will tend to
right the boat in the event of a roll over with the boards open.

>Another benefit is that I can remove some of the foam under the v-berth to
increase the available storage space. My target for total foam is about
35-36 cubic feet (the boat displaces several cubic feet with the cored deck,
fiberglass, etc). That should float a 1300 pound boat, 500 pounds of gear
and 600 pounds of passengers quite nicely... right side up too!

>But, I don't worry about knocking the P19 over... That's pretty hard to
do. Mainly, I'm putting the foam in to protect our heads from the bolts and
to reduce condensation when we sleep on board.
