In maritime navigation, visible white lights indicate a vessel's masthead light or stern light, while green lights signify the starboard side of a vessel. When encountering another vessel in darkness, if you see a green light, it means the vessel is approaching from your right side. Conversely, a visible white light could suggest that you are either approaching the stern of the vessel or that it is facing you. Understanding these light signals helps in determining the direction and movement of nearby vessels to avoid collisions.
The other vessel is coming directly toward the observer, so both the port and starboard running lights are visible.
You are approaching the port side of another vessel
It depends on the configuration seen. There are different lights visible depending on the relative headings of the vessels and relative sizes etc.
The other vessel is coming directly toward the observer, so both the port and starboard running lights are visible.
In darkness, a vessel displaying red and white lights indicates that it is a fishing vessel engaged in fishing activities. The red light typically signifies that the vessel is at anchor or restricted in its ability to maneuver, while the white light may be used to show that it is fishing. It is important for other vessels to exercise caution and maintain a safe distance from such vessels to avoid collisions.
In darkness or reduced visibility, visible red and green lights on a vessel indicate its orientation and direction of travel. A steady red light on the port (left) side and a steady green light on the starboard (right) side signify that the vessel is underway and facing the observer. If you see both red and green lights, it means you are approaching the bow of the vessel. If only one light is visible, it indicates the vessel's side, helping you assess its direction and take appropriate navigational actions.
