Re: Putting a A/C Unit in the Hatch on a Cat 27
5000 BTU's won't do much during the heat of the day, but an hour or two after the sun goes down, the boat will start to be fairly comfortable. I used to have one of those CruiseAires that were made to work in a deck hatch. Mine was an older one that only had 4750 BTU's and I cooled my Cat-30 with it. By midnight, the boat would cool enough that the thermostat would start to cycle on and off.
