Some of the ideas are quite good. There are some things to be wary
of. I'm an old boat lover and cabin cruisers are my thing. As far as
sealing off the area, it's the same principle as winterizing a boat.
Most boaters reccomend leaving cabinet doors open as well as vents
through the boat covers and things like that. If air cannot
occasionally move through an area, condensation and mold will form and
in a sealed quarter, it might be minimal but it will be there. The
foam idea would work but like many of the boats I've re-decked that
had good fiberglass finishes, let one little spot crack open and
you'll later find the foam to be water logged and very heavy. You wont
know it until the damage is done. I really like the drain plug idea
and have personally seen the benefits of and unrestored old Amphi that
had the grease coating in there. You can see through it with a
flashlight and even bare metal looks like new after 30+ years. It
worked great in the bilge too although not eye appealing but hey, keep
it covered and you'll never be bothered by it. Bobby
