I have Nexus and Global Entry because I fly every week for work but I almost never have a full crew with Nexus so I don't depend on that. On the west end of Lake Erie there are several video phones that can be used for reporting into the U.S. but in Cleveland there is only 1 and it's in a marina that doesn't have good transient dockage for bigger boats so most people docking in Cleveland skip the check-in process. Checking in to Canada is simple because they provide an 800 number to just call and report in. They also patrol the transient docks and you are expect to have your reporting number displayed on the dockside of the vessel if you are a non-Canadian flagged vessel.
