Final answer:
The overtaking vessel is the 'give-way' vessel and must ensure a safe pass, while the vessel being overtaken is the 'stand-on' vessel, maintaining its course and speed.
Step-by-step explanation:
When considering the rules of the road at sea, particularly when one vessel is overtaking another, there are specific maritime navigation rules that need to be followed. According to the International Regulations for Preventing Collisions at Sea (COLREGs), the vessel that is overtaking is referred to as the give way vessel. This means that it is the responsibility of the overtaking vessel to ensure that it can pass the vessel ahead safely without causing a collision or putting either vessel at risk.
The vessel being overtaken is known as the stand-on vessel, which means it should maintain its course and speed, allowing the give way vessel to make the necessary maneuvers to overtake safely. It's essential that both vessels communicate and understand their roles to prevent accidents. These rules apply to any body of water and are crucial for the safety of all at sea.
