The wife and I are planning on doing it if our 401(k) ever gets to the right number. We've been starting to pay more attention to the live-aboard type boats at boat shows lately. We got interested when we ran our Formula 600 miles down to North Carolina in 2004. We met tons of live-aboards who had done the trip several times and had nothing but great (and not-so-great but funny) stories to tell about the things that they had seen and done. Like RV retirees, there are lots of people doing this. Very, very cool trip.
