Which devices are commonly used for electronic distress signaling on boats?

• A. EPIRB and DSC.
• B. Smoke signals and hand flags.
• C. Flares only.
• D. Radio mics with no distress features.

Answer: (B)

Electronic distress signaling devices are those that actively transmit an alert and location to rescue services, rather than just being seen. The best answer is EPIRB and DSC. An EPIRB automatically sends a distress beacon detected by satellites and relayed to search-and-rescue authorities, providing your vessel’s identity and location, even if you’re unable to communicate. DSC, used with marine VHF radios, sends a digital distress signal that notifies rescue services and can include GPS position, allowing responders to locate you quickly. The other options rely on visual signals or non-distress audio gear. Smoke signals and hand flags require line-of-sight and good visibility, and they don’t transmit electronic alerts. Flares are visual signals as well, but they are pyrotechnic and not electronic. A radio microphone with no distress features won’t automatically alert authorities, so it doesn’t meet the need for recognized electronic distress signaling.
