All the previous replies seem to be valid tips for remote owners to visit their boat for extended periods. Of course, if the marina has a hard-line policy against extended stays you would be wise to follow the rules there or find another, more flexible marina. When you find a marina with a relaxed policy for your exteneded visitations, please contact the marina prior to each trip to your boat to inform them of your intentions (and get de-facto approval). Doing so may mitigate the live-aboards' objections. Chat up your neighbor boaters, especially the residents, to let them know your situation. For locations, please consider any port other that Marina Del Rey.
