Question 572Navigation General

The correct answer is B) Sailing Directions (Planning Guide). The Sailing Directions (Planning Guide) published by the National Geospatial-Intelligence Agency (NGA) requires infrequent corrections compared to the other options. This is because the Sailing Directions provide broad, general information about coastal and offshore navigational features, which are less likely to change frequently than more detailed publications like the Coast Pilot, Radio Navigational Aids, or List of Lights. The other options, A) Coast Pilot, C) Radio Navigational Aids, and D) List of Lights, require more frequent updates to reflect changes in coastal features, radio beacons, and lighted navigational aids, respectively. These publications contain more detailed, time-sensitive information that is subject to regular updates and corrections.
