>>28475560Depends mainly on where you want to live, size of your boat and what your docking fee is.
With some wrenching yourself and not picking some luxury sailing yacht but a fiberglass boat with good maintenance youll be looking at a minimum of 5k a year for savings to 15k a year for comfort. With a 25-40 foot boat you are living much more luxurious than any van desu, but you will have to pay up for that extra space and privacy. I couldnt live in a van and be treated like a homeless person needing to drive to the local 24/7 gym to take a shit at night.
