70% to pass

When using a buoy as an aid to navigation which of the following should be considered?

A The buoy may not be in the charted position.
B If the light is flashing the buoy should be considered to be in the charted location.
C The buoy should be considered to be in the charted position if it has been freshly painted.
D The buoy should be considered to always be in the charted position.
AI Explanation

The correct answer is A) The buoy may not be in the charted position. This is because buoys are subject to displacement by currents, tides, and other forces, and may not always be exactly at their charted position. Navigators should be aware that the buoy's actual position may differ from what is shown on the chart. The other answer choices are incorrect: B) The flashing light does not guarantee the buoy is in the charted location. C) The buoy's paint condition does not indicate its precise position. D) Buoys cannot be assumed to always be in the charted position.
