"At that point I would ask the question " where does the water go ? ".
To the coolest place it can get to and then condense.
Usually its the glass (with almost no R value) that will show the water first, but it will be condensing any place thats cold.
*Lockers , under the bunk matress , or behind any insulation on the hull thats not air tight .
I lived aboard for a couple of decades in NYC , coldest was a 3 -4 day snap to -17F.
Unreal, pouring the spagetti water down the drain would cover the bronze great cabin aft ,windows white with condensation that Immediatly froze.
Simple breathing caused enough condensation that the aluminum campanionway slide had to be beat on to slide open.
As G. Orwell would have remarked MUCH UNGOOD!
