When a vessel signals its distress by means of a gun or other explosive signal, the firing should be at approximately which time intervals?

🔍 Key Concepts

• Distress signals as listed in Annex IV of the Navigation Rules / COLREGS • The practical purpose of repeating a distress signal at a regular interval • Difference between very short, very long, and moderate time intervals for attracting attention

💭 Think About

• Think about how often a distress signal needs to be repeated so that other vessels and stations can notice it, but without wasting all resources immediately. • Compare each choice to what would be considered too slow to attract attention in an emergency versus so fast that you could not reasonably keep it up for a long period. • Imagine you are maintaining a gun or explosive signal by hand in bad weather—how much time between firings would still be realistic but urgent?

✅ Before You Answer

• Check Annex IV (Distress Signals) to confirm the recommended interval for repeated explosive or gun signals. • Verify which of the listed intervals would keep the signal clearly recognized as repeated and urgent, not a one‑off sound. • Eliminate any intervals that are obviously impractical for a sustained distress signal over many hours.
