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.
You are approaching a sailing vessel - head-on
The other vessel is coming directly toward the observer, so both the port and starboard running lights are visible.

You are approaching the starboard side of another vessel
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.
In darkness or reduced visibility, the white light indicates a vessel's stern, while red and green lights indicate the port (left) and starboard (right) sides, respectively. A vessel displaying a red light is facing another vessel, while a green light indicates it is on the starboard side. This color coding helps mariners determine the direction and type of vessel they are encountering, ensuring safe navigation.
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.
You are approaching the stern of another vessel
You are approaching the stern of another vessel and may be overtaking it
A visible white light indicates that the other vessel is a power-driven vessel.
A white light seen on a vessel in darkness indicates that the vessel is approaching you directly or near head-on. It suggests that both vessels should alter their course to avoid a collision, typically passing to the starboard (right) of the other vessel.
If you see a vessel displaying only a white light, it indicates that the vessel is a power-driven vessel. This vessel is approaching you head-on or is overtaking you. In both cases, you should be prepared to take action to avoid a collision.
