What is the name of the vessel that is NOT the give-way vessel in a collision risk situation?

Answer: B — Stand-on vessel

In a collision risk situation, the vessel that is designated as the stand-on vessel has the responsibility to maintain its course and speed in order to ensure safe navigation. The stand-on vessel is typically in a position where it is not expected to take evasive action, whereas the other vessel involved in the situation, known as the give-way vessel, must take action to avoid a collision. The reasoning behind this distinction is rooted in the rules of the road as outlined in the COLREGs. These rules aim to promote safe and predictable navigation at sea. By having one vessel maintain a steady course and speed, it allows the other vessel, which is required to give way, to assess and execute appropriate maneuvers to prevent a collision. Other terms like "passive vessel," "leading vessel," or "yielding vessel" do not represent formal classifications recognized in the COLREGs, making them less relevant in the context of maritime navigation responsibilities during collision risk scenarios. The use of "stand-on vessel" is specifically established within the regulations to describe the vessel that must hold its path in such situations, distinguishing it clearly from the give-way vessel.
