What is one critical aspect of navigating in close-quarters situations?

Detecting other vessels early is a critical aspect of navigating in close-quarters situations because it enables a vessel to assess potential risks and take timely action to prevent collisions. Early detection allows mariners to implement necessary navigational maneuvers, communicate effectively with nearby vessels, and make informed decisions that enhance safety. In close-quarters situations, where vessels are operating in limited space and may not have time to maneuver significantly, early identification of other ships is vital for maintaining safe distances and ensuring compliance with the rules of the road.

The other options reflect poor practices that could jeopardize safety at sea. Ignoring radar signals would prevent the navigator from being aware of other vessels in the vicinity. Maintaining a high speed to pass could increase the risk of collision, particularly if the vessel has not adequately assessed the situation. Relying solely on personal judgment over established navigation rules can lead to dangerous outcomes, as these rules are designed to provide structured guidance for safely navigating maritime situations.
