Question 73Navigation General70% to pass
Coast Pilots and navigational charts are kept corrected and up-to-date by using the _______________.
AI Explanation
The correct answer is A) Notices to Mariners.
Notices to Mariners are the primary means by which the U.S. Coast Guard and other maritime authorities disseminate information to update navigational charts and publications, such as Coast Pilots. These notices provide information on changes to aids to navigation, depths, hazards, and other critical data that mariners need to safely navigate. Coast Pilots and charts must be kept current by incorporating the changes published in the weekly Notices to Mariners.
The other options are incorrect because tide tables and current tables provide information on tidal and current conditions, while pilot charts depict general wind, current, and other climatological data, but do not directly update the navigational information contained in Coast Pilots and charts.
