Must a Search and Mission Coordinator (SMC) launch an assist for every automated distress call?

• A. Yes, always
• B. No; only if there is a reasonable search area or correlated evidence
• C. Only if the call includes a vessel identification
• D. Only during daylight

Answer: (B)

Determining when to launch an assist for automated distress calls hinges on evaluating credibility and available evidence rather than acting on the signal alone. An automated distress alert can indicate trouble, but without a credible search area or corroborating information, simply responding to every alert risks wasting resources and chasing false positives. The best practice is to proceed when there is a reasonable search area or other corroborating data—such as a known vessel in the vicinity, last contact or position, AIS or radar contacts near the last known point, or other evidence that points to a plausible distress scenario. This approach ensures that actions are justified by where a vessel might actually be and what information supports that possibility, while remaining prepared to respond promptly if clearer, actionable details emerge.

If a vessel identity is provided or a concrete location is known, that strengthens the case for a response, but even then the decision rests on whether the information creates a credible distress profile within the search parameters. The other options are too absolute or ignore the need for evidence: distress responses aren’t limited to daylight, and an alert with only a vessel ID or no locating information doesn’t automatically mandate a full assist.
