Your vessel has been ordered to proceed to the United Grain Growers Wharf at Thunder Bay, Lake Superior, for the purpose of taking on a load of wheat. Which publication(s) would you consult for such information as the length of the wharf, the depth of the water alongside, and the loading capacity at the facility?

Correct Answer: Option C — The United States Coast Pilot #6

The United States Coast Pilot, specifically Volume 6 for the Great Lakes, provides essential information for mariners, including detailed descriptions of harbor facilities, wharf dimensions, depths alongside, and available services. It is the authoritative reference for planning arrivals at specific terminals within the Great Lakes basin.
