Question 375Navigation General70% to pass
When a dual purpose marking is used, the mariner following the Intracoastal Waterway should be guided by the _______________.
AI Explanation
The correct answer is C) shape of the yellow mark.
When a dual purpose marking is used, the mariner following the Intracoastal Waterway should be guided by the shape of the yellow mark, not the color of the aid, the shape of the aid, or the color of the top band. The shape of the yellow mark indicates the side of the channel the aid is marking, which is the key information for a mariner navigating the Intracoastal Waterway.
The other options are incorrect because the color and shape of the overall aid, as well as the color of the top band, do not directly indicate the side of the channel being marked for Intracoastal Waterway navigation, which is the critical information needed when a dual purpose marking is in use.
