I think this comes from boats used for free time. They cost a lot and you spend relativly little time on it.

Now if you live on the boat you are using it which would make it more economical however I'm sure the upkeep and fuel costs more than a house would.

From my talks with boatowners / boatlivers on the river Cam in Cambridge, UK, the upkeep and fuel ain't too bad.
