What does it mean if you are the stand on vessel in and overtaking situation?

In an overtaking situation at sea, the "stand-on vessel" is the ship that has the right of way and should maintain its course and speed. The other vessel, known as the "give-way vessel," is required to take action to avoid a collision by altering its course or speed. It is crucial for the stand-on vessel to remain vigilant and aware of the give-way vessel's actions, as it still needs to be prepared to avoid an accident if necessary.
