What type of signaling is required in low visibility situations?

In low visibility situations, light signals become essential for communication and signaling distress or navigating safely through waters. This is primarily due to the limited visibility caused by fog, rain, or other environmental factors, which makes visual signals like flags ineffective and difficult to see.

Light signals can be seen from a greater distance compared to other forms of signaling and are more effective in conveying messages despite the low visibility. They can be utilized in various ways, such as using an all-round white light or a distress signal light, which are designed to attract attention and indicate a vessel in need of assistance or alert nearby vessels to danger.

While sound signals are also useful in low visibility to indicate a vessel's presence or intentions, they do not convey distress messages as effectively as light signals in terms of immediacy and visibility. Thus, in situations where visibility is compromised, utilizing light signals is paramount for safety and effective communication on the water.
