What color light should be displayed at the masthead by fishing boats?

Fishing boats are required to display a red and white light at the masthead when they are under way. The red light indicates the vessel's port side, while the white light serves as a signal that the boat is engaged in fishing activities. This configuration enhances visibility and helps communicate the vessel's status to other boat operators, ensuring safe navigation and reducing the risk of collisions.

The color combination of red and white is essential, as it signifies to other mariners that the vessel is a fishing boat that may have specific restrictions regarding its maneuverability due to the nature of its operations. This is particularly important during low visibility conditions, such as at dawn, dusk, or in fog.
