The starboard and port running lights are how many degrees?

The starboard and port running lights are each visible for 112.5 degrees on their respective sides of the vessel. This configuration allows vessels to be seen from a significant angle, facilitating navigation and safety on the water. The placement of the lights is designed such that the visibility arcs help other vessels identify the heading and orientation of the boat, which is crucial in avoiding collisions. The 112.5-degree sector ensures that boats can be seen from a wide swath of their approaches, particularly from the sides and rear, thereby enhancing situational awareness for all mariners.
