Being short of time this year with two boat projects under way, I elected
to have the yard shrink wrap "Strider". I just went up to pull the
hatches (see other post) and it was like a shower inside. My back quickly
became soaked bumping into the plastic. Maybe it was later in the season
but there never seemed to be a hint of moisture under the tarps. The wrap
has three of the little triangular vents on each side.

I had earlier opened up the portlights to let the gaskets spring back and
vent the inside of the boat. I wonder now if I'm letting more moisture in
than out.

I'm thinking of adding vents, perhaps one of those galvanized wind turbine
vents in a length of stove pipe taped into the double wrapping at the end.

Anyone else found a good way to get air flowing through a shrink wrapped
boat? Can I count on this moisture production slowing when the weather
gets colder and the boat has dried out?

I can now understand the warning never to shrink wrap a wooden boat.

It should be possible (although I haven't tried it) to install Nicro solar
day/night vents directly into the shrinkwrap covering. You'd need to find
flat horizontal spots in which to put them, one forward and one aft, but if
you already have a pair installed in your boat (or if you plan on installing
a pair) it's just a matter of moving them. Another option would be to find a
place both fore and aft which faces down -- under davits and bowsprit/pulpit
for example -- and cut large ventilation openings.
