Not Too Bad
I bought the larger 9,000 btu Heier unit at "Target" a few years ago and this particular item has the condensation evaporation feature, thereby eliminating any water discharge. For the money and convenience they are fine on cooling down our Catalina 30 cabin after a day of sailing, but in the heat of the summer it would require a 16,000 btu built in marine AC unit to cool us down below. They really are perfect for a good nights sleep aboard. The vent hose does give off heat but you the shorter you can get the hose or the closer the unit to a porthole for ventilation, the better! When the season is over it goes back in the garage. I looked at many portable options and the concensus was more in favor of the standard home AC window unit, followed by these stand up units then the cruise-air hatch units. For me trying to navigate over a window unit in the hatchway was enough to back off. The Heir is a great system and its portability and exhaust feature allows you to set it up at any part of the vessel where ventilation is possible. For the money they are worth it, but if you can buy the 9,000 BTU unit, especially since your in Florida. Bob30 Catalina
