Chartered a cat there a few years ago out of San Pedro. As has been said, it is very shallow, and GPS not accurate in places. The man who checked us out to us how to get free when (not if) we ran aground. Nothing like BVI is today - more like it was 30 years ago. Very few places to stop and eat once you pass Caye Caulker but you can be sure to find secluded anchorages and beaches. We stopped at a couple of "fish camps for dinner only to find out they were closed. I recall it was one long reach going down south and another long reach coming back north. Not much tacking involved, if any. Caye Caulker was a favorite stop. We stopped there on the way down and back. Also stayed in a hotel right across from the airport for a few days post-charter. That was really nice - good food and a decent spa.
