When navigating in thick fog with the radar on, what should you do?

In navigational situations involving thick fog, a multi-sensory approach is vital for safety. Keeping a lookout stationed as low down and far forward as possible is advantageous because it allows for a broader and clearer visual range. The person on lookout can better spot any hazards or other vessels that may not be reflected on radar. This positioning maximizes the lookout's ability to detect subtle changes in the environment, such as the presence of land, buoys, or other vessels that may not be immediately apparent through radar alone.

Although radar is an essential navigational tool, it has limitations, especially in poor visibility conditions. Relying solely on radar without a visual lookout may lead to missing critical information, such as the proximity of other vessels that could pose a collision risk. Thus, incorporating visual observation with radar monitoring enhances situational awareness and contributes to safer navigation.

In this scenario, the other options do not prioritize the combination of visual and technological aids that is crucial in thick fog. Turning off the radar would eliminate a valuable source of information, while simply monitoring radar without a lookout overlooks the need for direct visual assessments. Reducing speed and waiting for better conditions is a prudent choice in some circumstances, but it does not address the need for active monitoring of the
