Question 371Navigation General

The correct answer is C) you are in the vicinity of the ICW (Intracoastal Waterway). The yellow triangle on a buoy indicates that the buoy is marking the Intracoastal Waterway, a navigable inland waterway along the Atlantic and Gulf of Mexico coasts of the United States. Buoys with yellow triangles are used to delineate the path of the ICW, helping vessels navigate this important waterway. The other answer choices are incorrect because: A) a special mark buoy would have a different color scheme, B) a sharp turn in the channel would typically be marked with a different type of buoy, and D) an off-station buoy would not have a standard symbol like a yellow triangle.
