How much of an arc over the horizon does a sternlight cover?

135 degrees
225 degrees
360 degrees
112.5 degrees

The correct answer is: 135 degrees

The sternlight of a ship covers the area behind the ship, also called the stern. This light should be visible to an observer from a certain distance, indicating that a ship is approaching or moving away. Option A, 135 degrees, is the correct answer as it accurately represents the angle of the sternlight's visibility. Options B and C are incorrect as they cover a wider arc which would not be specific enough for an observer to accurately determine the direction of the ship. Option D, 112.5 degrees, is also incorrect as it does not cover enough of an arc to provide sufficient visibility for other ships. Therefore, it can be concluded that option A is the most appropriate and accurate choice.
