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 allows mariners to assess potential risks in a timely manner and take appropriate action to avoid collisions. Early detection facilitates better situational awareness, enabling navigators to evaluate the intentions of nearby vessels, their speeds, and their courses. This proactive approach is essential in congested or narrow waters where the risk of collision is heightened due to limited maneuvering space and reduced visibility.

In contrast, ignoring radar signals overlooks one of the key tools available for collision avoidance, which can lead to dangerous situations. Maintaining a high speed in close-quarter situations increases the risk of collision, as it reduces the time available to react and maneuver safely. Lastly, trusting personal judgment over established rules is problematic because it can lead to inconsistent decision-making and increased risk, as navigators may overlook vital regulations that are designed to ensure safe navigation.
