What procedure should be followed when moving a vessel in foggy conditions?

When navigating a vessel in foggy conditions, the primary concern is safety, not just for the vessel itself but also for other vessels and obstacles in the water. Keeping a close lookout and sounding signals is crucial in such situations. This practice involves being vigilant and using both visual observation and auditory signals to communicate with other vessels that may be nearby, enhancing overall safety.

In fog, visibility is severely reduced, and relying solely on speed or judgment to navigate can lead to dangerous situations, like collisions. Sound signals, such as horn blasts, are required by maritime law to help alert other boats to your presence and intentions. Failing to maintain a vigilant lookout while moving in low visibility significantly increases the risk of incidents on the water.

While anchoring until visibility improves and other options may seem reasonable, they don't address the need to maintain awareness of other vessels in the area, which is critical in foggy conditions. Ignoring fog and proceeding with caution is not a sound strategy because caution could lead to overconfidence and misjudgments. Therefore, the best procedure when moving in fog is to keep a close lookout and sound signals to ensure the safe navigation of your vessel and those around you.
