What does an all-round white light on a vessel signify?

An all-round white light on a vessel is designed to provide visibility from all directions. This type of light combines the functions of both a masthead light, which is visible from the front, and a stern light, which is visible from the rear. It is essential for ensuring that the vessel can be seen by other boats and objects in the water, especially in low-light conditions or at night. This function is crucial for promoting safety on the water, allowing other mariners to determine the vessel's position and heading.

This feature can be found on various types of vessels, not limited to anchored boats or specific types of vessels like fishing or sailing. It serves a broader purpose, enhancing the visibility of any vessel regardless of its activities.
