What is one key advantage of using radar during navigation?

Using radar during navigation provides the significant advantage of allowing quick fixes to be obtained. Radar can effectively detect and display the positions of other vessels, landmasses, and other navigational aids, even in poor visibility conditions such as fog, rain, or darkness. This capability is essential for maintaining situational awareness and making timely navigational decisions, thereby enhancing safety at sea.

The ability to obtain quick fixes means that boat crews can assess their position relative to navigational hazards rapidly, which is crucial in dynamic maritime environments. This quick assessment helps in avoiding collisions and ensuring safe navigation, making radar a vital tool in various weather conditions and at night, contrary to the suggestion that it only works in clear visibility.

The other options fail as they suggest limitations of radar usage that do not align with its capabilities, emphasizing why the ability to quickly obtain fixes is a key advantage in practical navigation scenarios.
