I just a refit with a new unit on my '93 36'. I went with a reverse cycle, CruiseAir 16k BTU system. In my boat. I have a U-shaped dinette so the unit was installed below the foreward seat, located against the bulkhead common with the head. We have it vented to the V-berth, Head, Salon, Galley and Aft Cabin. What I learned was that in order to maximize the cooling power of the unit, you need to move the maximum amount of air through the system. Therefore, we increased the size of the vent and vent opening in the salon in oder to meet this need. We also installed a digital monitor with 2 fan speeds. So far, we have been very pleased with the system. Of course, its still a boat without insallation, so on very hot days like we have been having here on the Chesepeake, it can only cool so much. But at least it does remove the humidity. Beacuse this was a refit, my total cost was $2,250 installed.Hope this helps!
