I use Active
Captain or
Google maps to find
anchorages,
marinas and services by location. I don't use Yelp or other 3rd party reviews at all. I read the write-ups in Active
Captain and read the reviews with a grain of
salt.
I typically need a decent sample of reviews to glean commonalities. Standout/standalone Yelp-style (1 star) complaints are ignored unless there is a pattern of them. Usually they are a long list of criticisms and when you get down to it, it turns out the server spilled soup on their lap or forgot their side salad.
