fishing at night
a sailing vessel is approaching head on and you must give way
Navigation lights, green starboard and red port. Masthead and stern lights should be white
You are seeing a vessel from the rear, or it is at anchor.
If you see green and white lights on another boat at night, it typically indicates that the boat is a power-driven vessel. The green light is on the starboard (right) side, while the white light is the masthead light, which shows the boat's direction. This configuration helps you determine the vessel's orientation and movement, allowing you to assess whether you need to yield or take action to avoid a collision.
It would mean that the other vessel is bow on to where you are looking.
A white light used by itself which can be seen in all directions is the anchor light, which means you are anchored. A white used in conjunction with bow lights (green and red) are your navigation lights. The white light indicates your stern ( back of boat). If all you can see is the white light, a boat is either anchored or underway going away from you.
Small boat light.
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.
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.
A green light is on the starboard side of the vessel. So it may mean that the starboard side is directly facing you.
