We visited White Bay for the first time last June with a E-SE wind and it felt pretty exposed - even on the north side of the mooring field. It is a nice place, but our 43 cat was putting enough pressure on the mooring ball that it was under water in a 15 kt. wind. We are pretty confident on anchor, but I would have preferred a mooring ball on this day. My assumption is that things died down some that evening, but we left in the afternoon so I can't speak to overnight conditions.
