What the numbers are for
The crane number is not bureaucracy; it is the rope’s name. When a line comes back to the bench twenty years later, Dan reads the whipping and finds the entry, and the crew knows what walked that day, who topped it, and what the weather was like off the river. A rope with a number has a history. A rope without one is just cordage.
