For any action taken to avoid collision, what is a key requirement?

A key requirement for any action taken to avoid collision is that it must be positive and made in ample time. This means that the maneuver must be clear and decisive, ensuring that the intended action will effectively prevent a collision. Taking timely action is crucial because delays in decision-making or execution can lead to dangerous situations, especially in congested or fast-moving areas. A positive action implies that the change in course or speed is not ambiguous, allowing other vessels to recognize and understand the maneuver, thereby enhancing overall navigational safety.

While signaling the action or requiring all nearby vessels to recognize the maneuver could be beneficial in some situations, it is not a foundational requirement for collision avoidance. The focus is on the promptness and clarity of the action taken rather than additional communication efforts that may vary depending on the circumstances.
