What type of distress signaling devices are required for larger vessels?

For larger vessels, VHF radios and Emergency Position Indicating Radio Beacons (EPIRBs) are essential distress signaling devices. VHF radios enable direct communication with other ships and shore stations, providing a necessary means to send out distress calls and receive assistance quickly during emergencies. They are equipped to broadcast on distress frequencies, ensuring that they can reach nearby vessels and maritime authorities effectively.

EPIRBs are crucial because they are specifically designed to alert search and rescue services. When activated, they transmit a distress signal that includes the vessel's location via satellite, which significantly increases the chances of a timely rescue. This capability is particularly important for larger vessels, which may operate far from the nearest help.

In contrast, while hand flares and smoke signals can serve as visual signals in distress situations, they are less reliable than electronic communication methods, especially in larger emergencies where rapid response is critical. Visual flags and lanterns might not provide the immediate notification and location tracking that VHF radios and EPIRBs can. Satellite phones and distress beacons also have their place but are not as standard or required as VHF radios and EPIRBs for larger vessels under maritime regulations.
