What direction should the masthead light be visible from while boating at night?

The masthead light on a vessel should be visible from the front and sides, specifically from 22.5 degrees on either side of the bow, extending to the stern. This light is white and must be displayed from sunset to sunrise, ensuring that other vessels can see your boat's heading and position. Proper visibility of the masthead light is crucial for safe navigation and collision avoidance at night.
