I have been thoroughly enjoying my recently acquired Catalina 22 this summer, and have hoped to spend a few nights on board, but the heat continues to hold me back. I understand that significantly cooling my cabin will not be cheap, but what is the most affordable way to cool my cabin to a comfortable sleeping level? Will I need to purchase a portable A/C unit (I have found some for around $100) and small generator? If so, can I get some suggestions? I am completely tolerant of the heat throughout the day, but am pretty particular about the temperature when it comes to sleep. Thank you.
