The masthead light covers how many degrees?

Explanation:
NAV lights are designed with specific visibility arcs to communicate a vessel’s orientation. The masthead light, a white forward light, is visible over a 225-degree arc. This means it can be seen from straight ahead and across the vessel’s sides to a point behind the beam on the other side, but not directly aft—the area behind is covered by the stern light. So the masthead light covers 225 degrees. The other options aren’t correct because the stern light covers 135 degrees, and an all-around 360-degree light is used for different situations (like when anchored), not the masthead light. An arc of 180 degrees isn’t the standard for any main navigation light.
