How much does it cost to live aboard a boat?
A pretty critical question, and fortunately, there are several resources available from sea-going bloggers who have kept track. Reading these over, it seems about $2000-2500 a month. The question on every cruisers lips is, “how long can I last?”
The best compiled resource seems to be The Cost of Cruising

Another good set of records that have been shared are several years worth

Being really frugal (and I mean REALLY) it would mean about $25,000 a year. I would think we would be closer to $35,000 by the time we figure in three hungry boys.
