What do green navigational lights indicate?

Green navigational lights indicate the starboard (right) side of the channel. In maritime navigation, lights are a critical part of the system that helps vessels understand their position and orientation in relation to navigational aids and the channel itself.

The color coding of the lights follows international standards whereby green marks the right side of the channel when entering from seaward. This convention assists mariners in identifying their course and ensuring safe navigation through narrow or congested waters.

This system of lights is integral to the overall regulatory framework guiding navigation and helps prevent collisions by providing critical information to vessel operators during both day and night. When a mariner sees a green light, they can be assured that they are on the correct path along the starboard side of the channel.
