When we stay on the boat for extended cruising, all in is about $3,800 per month. This includes towing the boat with tolls to Florida, stay at a hotel one night on the way down (too cold, no campgrounds), fuel for the boat, groceries, restaurants, sightseeing, marinas, and of course libations. Can you do it cheaper, probably, but we want to have fun and see all we can see, so we don't skimp. Now keep in mind that staying at marinas in Florida is more expensive then where you may be cruising. We like to break up being on the hook anywhere from 1 to 4 nights. In order of expense, food and liquor is number one, then marinas and then fuel. There is always debate about food and liquor being included, because you will do that at home as well. I find it hard to believe that with what I have included one can do it on $1,000 per month.
