Question 1428Navigation General

The correct answer is A) continue on the present course. When you are steering on a pair of range lights and the upper light is above the lower light, this indicates that you are on the correct course and should continue on your present heading. The vertical alignment of the range lights is designed to help the mariner stay on the proper course. As long as the lights remain in a vertical line, with the upper light above the lower light, you are following the channel or navigation path as intended. The other options are incorrect because: B) coming right or C) coming left would take you off the proper course indicated by the range lights, and D) waiting until the lights are no longer in a vertical line would be the wrong action, as that would mean you have already deviated from the intended course.
