There's yet another downside: Bnb patrons have a bad rep at the marinas
: they get drunk and do destructive things like turning boats loose. No way I'd want one in a marina I was staying at. Landlubbers do not know how to BE on boats.
Please understand, this is not against the OP, but it is how it is in the world. Nobody who cares about their boat
like a cruising couple does will want bnb boats there. You've been out sailing, you come "home", and there's a loud party, or boats have been cast loose in the marina, creating a hazard, nope, no way.
