I am trying to remember whether you can anchor at Havre Aubert. There were about five cruising boats there and all were tied up to the very substantial dock in front of the Club Nautique. There was a reasonably large bay next to the dock but I seem to remember that it was quite shallow. You could ask the locals about the actual depths since the chart was not very detailed.
It is lovely spot to visit, enjoy.
In South Africa doing lots of boat stuff. Departure north from Cape Town around December 15th. Arrival in the Caribbean around the beginning of February, after 5300 miles or so.
