Final answer:
In navigation, when one vessel is overtaking another, the overtaking vessel is the give way vessel, responsible for avoiding a collision by changing its course or speed.
Step-by-step explanation:
When one vessel is overtaking another, the rules of navigation dictate that the overtaking vessel is the give way vessel. This is similar across many different types of navigation, whether on the water or the road. The give way vessel is responsible for taking action to avoid a collision, which typically involves altering its course, speed, or both to ensure safe passage around the vessel being overtaken. The vessel being overtaken is known as the stand-on vessel and should maintain its course and speed unless it becomes clear that the give way vessel is not taking appropriate action.
