Nautical Term: Masthead light
Definition of Masthead light
A masthead light is a powerful white light that is mounted at the top of a vessel’s mast. This light is essential for ensuring the safety of the vessel and other nearby ships, particularly during periods of limited visibility such as fog or nighttime.
For example, consider a steam vessel that is underway during the night. In order to comply with international maritime regulations, this vessel must display a masthead light at the top of its foremast. This powerful white light helps to ensure the safety of the vessel and other nearby ships by making them more easily visible to each other.
