Detroit and St. Claire Rivers
This is a reply I received on the same question. I think I have a more detailed reply at home. I will check tonight.
If you have enough crew to go round the clock, can make it from Cleveland to
the N/C in about 48 hours, give or take.
If you spent 10-12 hrs/day, takes about a week.
Takes 2 days to get to Metro Beach, another day to Port Huron, then another
3 days up the Mi side to Rogers or Mac City and then a day across.
Another 12-14 hr day from "Tub" to ? (forgot name, about 70 miles South and
past the Nuke Plant on the Canadian side), than another long day back to
Stay well off shore and go straight in on the Canadian side, especially
around Pt Clarke.
