[C320-list] Air Conditioning

[Warren Updike]

Irv, that's exactly what I did; and, am able to open the hatches and leave
the screens in-place. I leave them on when away from the boat and it helps
cut the heat load and temps in the cabin.

An idea just occurred to me.

If you were to attach fabric straps to the plug, you could put the
insulating plug on to top side of the hatch with the straps  under the hatch
so that if in evening,  you could open the hatch to let air in.

Just an idea
