Newport/Martha's Vineyard/Nantucket--your feedbacked needed!
Yes I've got all that but where do you make the cut south? Woods hole or between Nashaweena and Pasque? I imagine you want to leave Cuttyhunk Harbour at slack tide? How does that work with the tidal current charts? I would think slack low tide would correspond to the flood starting in Buzzard Bay but at that time the current is ebbing out of Vineyard Sound.
