We have no ‘Windows’ lol. We have 6 large port lights in the saloon, 1 small one in the double guest port and 4 smaller ones toward th bow in the master berth and head. None of them open except the small one in the double berth. The rest are all new deadlights. I probably wouldn’t mess with it anyway for a wk or 2 out of the year. That’s why I said inside the companionway. It would be portable/moveable.
Well...window meaning home window A/C unit. Easy to install in a cabin cruiser sliding window. I thought if a portlight doesn’t open, then it’s a deadlight.
Went to `companionway hatch’. You’ve probably figured out by now I’m a former stinkpotter (more headroom).
If I owned a sailboat & wanted A/C while in port, it would involve blowing refrigerated air downward through the companionway using a dismountable unit that would be stowed while under way.
That was then. Now we go to our oceanfront timeshare, walk on the beach & watch the sailboats in open water.
