First thing my father in law taught me about navigating his sailboat was RED RIGHT RETURN. Keep the Red Nuns on the Starboard side when coming back into the harbor/river from the ocean. Therefore, keep the Green Cans on the port side.
Then it is just the opposite when going out to sea.

Does a ship like this have a Pilot for navigating the entire Chesapeake Bay or just going into the port of Baltimore?

Good question:

“By state law, every ship that enters Maryland waters must have a state-licensed pilot at its helm, steering massive ships from the sea into port. That means that every vessel bound for Baltimore must be met by a pilot at the mouth of the Chesapeake Bay, where she or he takes command of the ship. Throughout this voyage, pilots steer their ships through a 50-foot deep channel, with sometimes as little clearance between the bottom of the ship and the bottom of the Bay as three feet. Once the ship reaches the Key Bridge, a docking pilot takes over the helm and brings the ship into its berth in the Port.”
