I live in Oriental, NC. There isn't a liveaboard
community as such, but most marinas
don't prohibit liveaboards, although some charge a LA fee. Live aboard slips for a 40'er will cost $3-400/mo, sometimes with and sometimes without utilities.
Oriental is a large boating
community with three times as many boats as residents, two boatyards
and lots of independent contractors working in the area. Port Supply makes a run to the small West Marine
store and surrounding yards weekly.
Transportation beyond can be difficult. It is a 45 minute drive to a small regional airport
in New Bern that flys to Atlanta and Charlotte. That gets us everywhere we want to go. Raleigh is another two hours away.
The climate is tough in the summer- 85-95 and humid in July and August, decent in the winter- lows in the 30s and highs in the 50s in Jan and Feb. And in between it is delightful.
Services are cheap
compared to other places suggested such as Charleston, although medical
care is more expensive than average IMO and you have to go to New Bern for almost everything.
