Where we are we’re pretty lucky that it doesn’t usually get that hot. Yeah you can’t escape from the heat on a boat. We had a week of really hot temps here this last summer. Was 90 degrees in here. I actually drove to Lowes and walked up and down every aisle just to get cool. lol
Made me think about buying a small window unit to set in the companionway for just those days.
I googled “companionway hatch A/C”. Units that mount in the companionway seem to just block it off. One solution is a deck mounted window unit with a shroud that ducts cool air down into the bow hatch. All kinds of ways in the photos.
LOL, forty years later I’m still fascinated with air conditioning a boat cabin. As long as you’re connected to shore power, anything is possible. That 42’ Chrissie I mentioned had all the electric amenities, but no generator. Guess where it spent most of its days.
