Question 569Navigation General

The correct answer is B) Sailing Directions (Planning Guide). The Sailing Directions (Planning Guide) contains information on ocean routes, including details on prevailing winds, currents, and other navigational considerations for planning a voyage across the open ocean. This publication is the appropriate reference for planning a long-distance voyage like the one from San Francisco to Japan. The other options are not the correct references for this type of information. Sailing Directions (Enroute) provides more detailed, localized information for coastal navigation. The World Port Index contains information on ports and harbors, but not on open ocean routes. The Coast Pilot also focuses on coastal navigation, not on ocean voyages.
