What color of lights indicates that you are the stand-on vessel?

The designation of the stand-on vessel is crucial in marine navigation and safety. When a vessel is identified as the stand-on vessel, it means that this vessel has the right of way in a crossing situation. According to international navigation rules, the stand-on vessel displays specific signaling lights.

The correct answer, which is green and white, reflects that the vessel is likely to be a power-driven vessel underway at night. The green light indicates the starboard side, while the white light is the masthead light, which helps other vessels determine the position and heading of the stand-on vessel. These colors are essential for other vessels to recognize which vessel has the right of way and to ensure safe navigation.

Understanding the specific combination of lights associated with each type of vessel is critical for all mariners to avoid collisions and adhere to maritime traffic rules. The other combinations of light colors either do not correspond to the identification of the stand-on vessel or are not standardized under the rules governing navigation safety.
