Has anyone had any luck using a portable AC unit to cool their berthing area and wheelhouse. The way my boat is set up I am going to need alot of BTUs to cool off my "greenhouse" like wheelhouse. The wallet is getting thin heading into the final stretch of this refit and I was looking for a cheap simple solution to keep the crew cool and happy for the next few months. I have plenty of room to fit two 16k BTU units in the wheelhouse and it will be easy to vent straight through the winterback , Down below gets a little more tricky but can be done without too much trouble. Any first hand experience?
