It is disappointing to read about other's experiences with poor chart briefings. A good chart briefing can be extremely helpful and a valuable use of time. I have chartered with Moorings in BVI, Croatia, and French Polynesia. I will say that the briefings in Croatia and FP were much more thorough and valuable than the BVI briefing.

But when done correctly, a good briefing can answer many of the questions posted on this site with up to date information. In addition to navigation questions, other questions like: "Do you know of any quiet anchorages that we should visit?" Or, "Are there new restaurants that we should try?" can be part of a good briefing. Maybe as paying customers we need to demand better chart briefings...
