Question 739 Rules of the Road

The correct answer is C) stern light. According to the Rules of the Road, a towing light is a yellow light having the same characteristics as a stern light. The stern light is defined as a white light placed as nearly as practicable at the stern, showing an unbroken light over an arc of the horizon of 135 degrees and so fixed as to show the light from right aft to 67.5 degrees from the stern on each side of the vessel. The other options are incorrect because an all-round light, sidelight, and masthead light have different characteristics than a towing light as defined in the regulations.
