What action should a vessel take when it is determined to be the give-way vessel?

Answer: B — Alter its course or speed to avoid a collision

When a vessel is determined to be the give-way vessel, it is required to take action to avoid a collision by altering its course or speed. This principle is grounded in maritime navigation rules which prioritize safety and the prevention of accidents on the water. The give-way vessel is typically in a position to maneuver and must do so to afford the stand-on vessel the opportunity to maintain its course and speed. This action can involve shifting the vessel's path to either starboard or port, or reducing its speed to create safe distance and time to ensure that a collision does not occur. Adhering to this rule fosters responsible navigation and helps ensure the safety of all vessels involved. Other options, such as continuing at the same speed or increasing speed, do not align with the responsibilities of the give-way vessel, as these actions may heighten the risk of an accident. Signaling intentions is important and can assist in communication but is not a substitute for the obligation to take action to avoid collision.
