Re: Air conditioner for 1979 carver mariner
A year ago I bought a 16K home portable unit on CL. I "plumbed" the 6" exhaust to one of the portlights (used an old one that was all scratched up). Works great cooling our salon on a 35' aft cabin, but doesn't circulate back to the aft cabin. The downside with these kind of portables is that they are constantly sucking in outside air (hot, humid) into the boat that it has to fight. It stills works, but not nearly as good as a true marine unit.
This year I picked up a 7K marine unit that I'm going to install in the aft cabin. I have it temp'd in right now, and it's cooling things just fine.

Your boat is a big plastic "terrarium" with no insulation, it takes a lot to keep it cool.

KM what is a space blanket......

It's a really, really thin piece of plastic that has a really really thin piece of foil on both sides. They are also called survival blankets because they are light and compact but you can wrap yourself up in it to conserve heat if stuck outdoors. The foil reflects nearly 100% of the IR radiation back to your body to retain heat, or away from you to keep you cool.
It's amazing how much the cabin heats up when the sun is beating on it. A week ago I was cleaning the dingy cover, and needed to stretch it back out when it was drying. I hooked it in four corners and put it over the cabin to dry out. You would have thought I turned on the A/C by how quickly the cabin cooled off!!
