Retirement Living TV is an interesting site with various videos concerning, what else, retirement living. They have advice segments and various special interest clips. This one covered a man living on a 49′ boat, and then had an interview with a Yacht broker concerning some of the facts of life of buying and living on a boat.
It was an interesting five minutes, and the hosts actually seemed somewhat surprised by several of the answers. Make sure and listen to the last 30 seconds… they discussed the social aspects of boating and living aboard, with a lot of stress given to the fact that it wasn’t a "loner" lifestyle.
