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.
Back to Grenada in early December. Not sure I will remember how to sail. Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
