What visual aide should you use to navigate through fog?

Using a sound signal or horn to navigate through fog is crucial because visibility is significantly reduced in these conditions. The primary concern while navigating in fog is the inability to see other vessels or markings, making auditory signals vital for safety.

Sound signals help communicate your presence to other boaters, which is essential to avoid collisions. For instance, boats are required to use sound signals at regular intervals while in fog to alert others of their location.

While electronic navigation tools and GPS can assist in determining your position and course, they do not replace the need for sound signals in low visibility conditions. Additionally, relying solely on visual markers or GPS can be dangerous, as they may not be immediately visible or accurate in foggy weather. Thus, using sound signals is an important practice that enhances safety on the water during foggy conditions.
