very simple way of doing it.......dont call yourselve a
liveaboard.. start using the term cruiser and you can uasally stay in a marina for 3 to 4 months without a problem..
we would stop in somewhere, mention that we were passing through and wanted to stop for a couple months and do some sight seeing.. completely different attitude when they know that you arnt moving in to stay and hanging your cloths line up on the
dock..
many times we negosheated (sp) the term and got the
price alot lower if we paid for two or three months up front,,
just call ahead and tell them that you are on your way south and would like to explore the area for awhile.. you'd be surprised at how receptive they are.. after a couple months, start looking for another place..
we hopped around the northwest for 5 years and whenever we would leave, they would always ask us to come stay again when passing through..
