Question 139Navigation General

The correct answer is A) lighted with a white light. Vertically-striped buoys, also known as safe water marks, are used to indicate the center of a navigable channel or fairway. These buoys are typically lighted with a white light, which helps mariners identify the safe passage. This is in accordance with the U.S. Aids to Navigation System, which specifies the characteristics of different types of buoys and their corresponding lighting. The other answer choices are incorrect because: B) lighted with a red light is not the correct color for a vertically-striped buoy; C) striped black and yellow is the color scheme for a special purpose buoy; and D) striped black and green is the color scheme for a preferred channel buoy.
