What's possible is not the issue. The issue is would I want to be stuck inside the cabin of a boat, a slave to the AC. I just don't see the point, but then, I live in SoCal and sail in the Pacific Ocean. We sometimes want a little heat cause that water is cold and it makes the air cooler and dryer. I was in Florida once, Tampa Bay, walking around a small marina. The place seemed deserted, until someone told me everyone was below, hanging out in the AC.
