Question 826 Rules of the Road

The correct answer is A) turn off the red over green, turn on the white masthead light. This is correct because when a sailing vessel is using its auxiliary engine, it is considered a power-driven vessel, not a sailing vessel. As a power-driven vessel, it must display the appropriate navigation lights, which include a white masthead light instead of the red over green light. Turning off the red over green light and turning on the white masthead light ensures the vessel is displaying the correct navigation lights for a power-driven vessel. The other options are incorrect because B) showing two green lights is not the proper light configuration for a power-driven vessel, C) turning off the stern light would be incorrect, and D) displaying a white light alone does not meet the requirements for the navigation lights of a power-driven vessel.
