A couple more downsides to shrink wrap: there's no ventilation in a
shrink-wrapped boat..it traps and holds humidity, resulting in moldy
musty interiors next spring. You can't go aboard on any of those
occasional amazing days in the middle of winter to open it up to let it
air out, or check on anything--like finding out whether any critters
have decided to homestead your cabin--or do any of those little projects
you should do this fall, but didn't and COULD do if you could go aboard
for a day.

IMO, you're a lot better off giving your hull and deck a heavy coat of
wax to protect the fiberglass...and then cover it instead of
shrinkwrapping it.

A couple of winters ago, when the guy I crew with used shrink wrap on
his Mirage 33, he had at least two vents and a zippered access door
taped in. It worked great...but is a bit expensive.
