Question 282Navigation General

The correct answer is D) quick flashing. A buoy with red and green horizontal bands indicates that it is a preferred channel marker, which means that vessels should pass the buoy on the side indicated by the color of the top band. The light characteristic for a preferred channel marker buoy is quick flashing, which means the light will flash repeatedly at a rate of 60-80 flashes per minute. The other answer choices are incorrect because Morse code is not a light characteristic, interrupted quick flashing is not the correct light characteristic for a preferred channel marker buoy, and quick flashing is the proper light characteristic.
