Question 338Navigation General

The correct answer is D) None of the above. A survey (special purpose mark) buoy is not required to have any type of light. These buoys are used to mark the boundaries or locations of various features or activities that are not for the purpose of navigation, such as the boundaries of a survey area or the location of a submerged object. Unlike navigational buoys, survey buoys are not required by regulation to have any specific lighting configuration. The other answer choices, A) fixed white light and B) flashing red light, are incorrect because they describe lighting requirements for other types of buoys, not survey buoys specifically.
