70% to pass

When a buoy is in position only during a certain period of the year, where may the dates when the buoy is in position be found?

A On the chart
B Notice to Mariners
C Light List
D Coast Pilot
AI Explanation

The correct answer is C) Light List. The Light List is the definitive source for information on the dates when seasonal buoys are in position. The Light List provides detailed information on all aids to navigation, including the seasonal status and dates of operation for buoys that are only in position during certain times of the year. This makes the Light List the most authoritative reference for determining when a specific buoy will be in place. The other options are incorrect because: A) Charts do not typically specify the seasonal dates for buoys, B) Notice to Mariners provides temporary updates but not comprehensive seasonal information, and D) Coast Pilots provide general navigational information but not the level of detail found in the Light List.
