We had two power cats this last Feb. During the check out briefing, my friend was told his water maker worked and I was told "mine didn't" > end of story.
We just got back from chartering a 41.3 mono > water maker worked fine. It produced ~ 15 gallons per hour. We were told to monitor it (no auto shut off when tank was full"). We produced water while on the mooring ball with generator on and running on one of the two AC's at the time (We had issues running both AC's anyway).
I would think > 90% of the equation is making sure it works at time of check out.
We were flatly told > it didn't work on our first trip.
