I am going to disagree with the great holding in great harbor. Before the moorings balls were put in it was noted as a tough place to get a anchor properly set. It was rare that I could back down on the anchor at my desired RPM and not have it drag. It often took 3 or 4 attempts to get a set I was happy with. The good news is that’s it’s generally well sheltered unless you get a storm generating a strong south wind.
