And the Huron Spirit

 Since the Ronnie is a salty, it would stand to reason that I would be seeing the pilot boat.

All saltwater vessels on the Great Lakes are required to have a Great Lakes certified pilot.

One of the pilot change points is Port Huron.  From here, the pilot will take the ship either to Detour where there will be another pilot change or to their destination in Indiana.

Another pilot change point is Detroit.

Anyway, this is a pretty neat looking boat.
