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.
Heading back to Lake Ontario for this summer. Relatively few stops along the way from Grenada. Martinique, Guadeloupe, St. Martin (must have something to do with the French food), then Bermuda, New England and up the Hudson/Erie Canal. We were going to go via Newfoundland and Labrador but June remembered that one of the kids is getting married this summer - details, details!
