Maintenance on that boat will be far more than maintenance of a home even if you do most of the labor yourself; gas on that boat will be more than the gas of your car and the electricity bill; you'll spend more on maintaining the water pumping and filtering than you pay for water in your home, mooring fees to dock for your supplies will be far more than you've ever paid for parking a car, etc, etc. "Cheap" is relative, but you're comparing apples with oranges if you compare the purchase price of a boat to all the expenses of living in a house - all the expenses are still there, and everything is more expensive in the sea.
