How does a vessel at anchor signal using a fog bell?

A vessel at anchor signals its presence in foggy conditions using a fog bell by ringing it once every minute. This signal is a recognized maritime signaling protocol intended to warn nearby vessels of its position to prevent collisions. The practice of one ring per minute is a standard that allows other vessels, especially those navigating in reduced visibility, to locate the anchored vessel.

Understanding this protocol is crucial for safety while operating a pleasure craft, as it demonstrates the importance of communication between vessels in limited visibility. Clubbing together with other signaling practices, such as using the appropriate sound signals according to the International Regulations for Preventing Collisions at Sea (COLREGs), enhances maritime safety.
