A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards like rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. What is being signaled when you hear 5 short blasts from another vessel's horn? One prolonged blast is a warning signal for example, used when coming around a blind bend or leaving a dock.
Five or more short, rapid blasts signal danger or signal that you do not understand or that you disagree with the other boater's intentions. What does 6 blasts on a ship's horn mean? That is the signal for abandon ship and is directing the crew to their abandon ship stations. This signal is sounded on both the ship's whistle horn and the internal alarm.
What do fog horn blasts mean? The use of appropriate foghorn sound signals in foggy conditions indicate whether the vessel is sailing or motoring, aground, or at anchor. Fog horn sound signals are either prolonged four to six seconds or short one second. If agreement is not reached, then whistle signals shall be exchanged in a timely manner and shall prevail.
In or near an area of restricted visibility, whether by day or night, the signals prescribed in this subsection shall be used as follows:. When practicable, this signal shall be made immediately after the signal made by the towing vessel. In a vessel of one hundred meters A vessel at anchor may in addition sound three blasts in succession, namely one short, one prolonged and one short blast, to give warning of her position and of the possibility of collision to an approaching vessel.
