No Agenda, We've made the trip from Port Clinton to the North Channel 3 times with the limitation of a two week vacation. I'd suggest making the trip to Port Huron the weekend before your vacation. You can leave your boat on the wall of the Black River for a reasonable price. In a 30' boat the best SOG you will achieve is 4 knots and the south light of the Detroit River to Port Huron is 80 miles.
