When a powerboat is operating at night, it should display a red light on its port (left) side. This red light is part of the boat's navigation lights, which help other vessels determine its direction and orientation. The starboard (right) side should show a green light, while a white light is typically displayed at the stern.
If you are operating a powerboat at night your green side light must be visible to boats approaching over an arc of the horizon 112.5 degrees and so fixed as to show the the light from right ahead to 22.5 degrees abaft of the beam on its respective side.
When a powerboat is operating at night, it must display a red light on its port (left) side. This is part of the navigation lighting requirements to ensure safe passage and to indicate the direction of the vessel to other boats. The red light helps other vessels determine the boat's orientation and direction of travel. Additionally, a white light is typically shown at the stern and a green light on the starboard (right) side.
When operating a powerboat at night, seeing a green light on another boat indicates that the vessel is facing you from the starboard (right) side, while the white light suggests it is likely a powerboat. According to navigation rules, the green light is a sidelights indicating which way the other boat is oriented. You should maintain a safe distance and be prepared to take evasive action if necessary.
That what you see is a sailboat. The green light means you must give way.
When a powerboat is operating at night, the white masthead light must be visible from both the front (fore) and the sides of the vessel. It should be mounted at least 1 meter above the sidelights and visible from an angle of 225 degrees. This ensures that other vessels can see the powerboat's position and direction of travel, enhancing safety on the water.
If you see both the bow lights, the approaching ship is coming at you head-on.
