The international regulations for preventing collisions at sea state that a vessel of any length must sound a signal of seven short blasts when operating in restricted visibility. This includes fog, hail, heavy rain, snow, or strong winds.
This signal indicates that a vessel is in an environment with limited visibility and is trying to warn other vessels to be extra cautious while navigating in order to prevent a collision. This signal is also known as a danger signal and is used to alter other boats of the vessel’s presence, position, and direction.
Additionally, vessels that are operating with restricted vision are required to sound this signal once every 2 minutes. Vessels that are under way should also sound this signal twice before crossing paths with another vessel.
This system is in place to help reduce the number of potential collisions on the water.
What is the signal for man overboard?
