We locked down through the Soo Locks today. Our trip from Duluth took us through Marquette, Munising, Grand Marais and Whitefish Point. I can give you up to date info on all harbors.
We went down the American locks because we did not want to confuse the CBP. It's tough enough already to comply with the regs and interpretation varies. There was no delay and the locks were equipped to handle small boats. Easier than locking down the big Mississippi
locks in Minneapolis. Hail "American Lock" on channel 14.
Enrolling in the CBP SVRS system might make dealing with CBP easier because it is easy for them to verify you are legit. We were stopped by them as we exited Lake Superior
We were also stopped by the USCGS earlier in our trip. They are very professional and friendly but you need to make sure you have your passport, boat registration
in order. The USCG will also check your safety equipment
, holding tank
and bilge/oil pads.
