Which of the following is NOT considered a standard distress signal under MARPOL and related regulations?

In maritime safety regulations, distress signals must be standardized and detectable by rescue authorities. Flares provide a clear, visible sign of distress that can be seen from a distance, and EPIRBs emit a radio beacon that directly alerts rescue coordination centers with your location. Electronic distress signals, such as those using DSC on radios or satellite beacons, automatically transmit a distress alert with your position to the appropriate rescue services. These signals are designed to be internationally recognized and monitored, ensuring a prompt response. A ship’s whistle or horn signaling alone does not meet those standards. It can attract nearby vessels, but it doesn’t convey a formal distress alert or location to search-and-rescue authorities, and it isn’t monitored by the rescue network. Therefore, while useful for routine signaling, it isn’t considered a standard distress signal under MARPOL and related regulations.
