Great Lakes navigation guides
I need to transit the Great Lakes from Lake Superior to East Coast. Preferable via Hudson River, if not, then Gulf of St Lawrence. Nordhavn 46 with 5’5” draft, 27’ air draft mast up and 19’ mast down. From what I can find on line, I might be able to transit the Oswego to Erie Canal route mast down. I see text indicating 21’ air draft, but looking at Bluechart there appears to be 19’ fixed bridge. Can anyone recommend best cruising guides and route for this trip?
