Question 230Navigation General

The correct answer is D. Color sectors are not expressed in degrees from the light toward the vessel. Color sectors of lights indicate important navigational information, such as the location of turning points, shallow waters, or dangerous areas. However, the color sectors are defined in relation to the light itself, not in relation to the vessel. The boundaries of the color sectors are defined by specific bearings from the light, not by degrees from the light toward the vessel. The other answer options are incorrect because they accurately describe the purpose and meaning of color sectors, but they do not address the relationship between the color sectors and the vessel.
