For the most part, one rarely doesn't have a reasonably good breeze in most anchorages in the Tampa Bay area or anywhere on the southwest coast of Florida except, perhaps, for the really urban locations that most wouldn't choose to
anchor in anyway. With the breeze; and, some good awnings to keep the sun off the deck, most boats are reasonably comfortable. Once the sun sets, except on rare occassions, things cool off pretty well and one is usually quite comfortable with only a few fans to keep the air moving below. We have a generator and can run the AC while anchored out, if necessary, but rarely have. Note, however, that in most marinas, where there is little wind, one does need AC unless one is made of sturner stuff than we!
FWIW...
