Question 529Navigation General

70% to pass

Charts should be corrected by using information published in the _______________.

A Notice to Mariners
B American Practical Navigator
C Light List
D Coast Pilot
AI Explanation

The correct answer is A) Notice to Mariners. Notices to Mariners are the primary source of information used to update and correct nautical charts. These notices provide the latest updates on changes to aids to navigation, depth soundings, and other critical information that affects the safety of navigation. Navigators are required to use Notices to Mariners to ensure their charts are current and accurate. The other options are incorrect because: B) The American Practical Navigator is a reference book, not the source for chart corrections; C) The Light List contains information on lights and other aids to navigation, but does not provide the comprehensive chart updates found in Notices to Mariners; and D) Coast Pilots provide descriptive information about coastal areas, but do not contain the specific chart correction data.
