When overtaking another vessel, which action is required by the overtaking vessel?

When overtaking another vessel, the overtaking vessel is required to give way to the vessel being overtaken. This is in accordance with the navigational rules that state that the priorities of vessels at sea require that the vessel that is not constrained by its ability to maneuver, which is typically the overtaken vessel, retains the right of way.

The overtaking vessel must ensure it allows the vessel ahead to continue its course and speed without any alterations. This action is critical for the safety of navigation as it prevents potential collisions and ensures that the overtaken vessel can proceed unimpeded.

Other choices may seem plausible; however, they do not accurately reflect the obligation of the overtaking vessel as defined by maritime rules. Sounding a horn or maintaining speed and course would not prioritize the safety and right of way of the vessel being overtaken, while warning other vessels, while a good practice, does not specifically address the rule for overtaking vessels.
