After-market cabin ventilation

[rapscallion]

I recently purchased a 1982 Carver 3007 aft cabin. Great boat, but there is no system for ventilating the cabin spaces while the boat is locked up and not being used. I live in the PNW where I don't have to fully winterize the boat, and where it rains a LOT. I'm concerned about mold and mildew as a result of poor air circulation in the cabin. I have a West Marine air dryer, which runs continuously when I'm not on the boat. I recently purchased, but haven't installed, one of those solar powered vents. I was thinking of installing it in the forward hatch, but there should be at least one passive cowl vent elsewhere to provide an air intake. Where to install one of those. I don't particularly like the look of the solar vent installed in the forward hatch.

I'm curious what others are doing to keep the air flowing in the cabin spaces of their older Carvers?

I have a 97 350 Mariner and last winter I left one port hole near the stove and the ladder hatch cracked with a 110V 1500 Watt West Marine Heater running and had no problems. The area on the bridge stayed warm because of the hatch (remember, this is the model with the ladder in the salon). My boat was also under cover. When it got really cold I put a heat stick in the ER to keep the H2O lines back there from freezing as well as one in the under dash area to keep the H2O lines running to the ice maker from freezing (always did like the idea of the wet bar right by the helm )

My boat 36 mariner has a lot of space under the bridge I was thinking of running a fan in there pulling from the galley
