Question 574Navigation General

The correct answer is D) World Port Index. The World Port Index is the primary publication that provides general information about the location, characteristics, facilities, and services for U.S. and foreign ports. This publication, produced by the National Geospatial-Intelligence Agency, contains detailed descriptions of over 3,700 ports and terminals around the world, making it the comprehensive reference for this type of information. The other options are incorrect because: A) Distances Between Ports does not contain the level of detail about port characteristics, B) Coast Pilot focuses on navigational information for specific coastlines, and C) Sailing Directions provide navigational information for specific routes, but do not have the breadth of port data found in the World Port Index.
