A short blast is typically about how many seconds in duration?

• A. 3-4 seconds
• B. 1-2 seconds
• C. 0.5 seconds
• D. 5-6 seconds

Answer: (B)

A short blast is a quick, concise sound signaling used to convey immediate action or intent on the water. It should be about one second in duration, with some guidance allowing up to roughly two seconds. Anything longer—three to four seconds or five to six seconds—would be considered a prolonged signal, not a short one. A half-second burst is generally too brief to count as a standard short blast. So the best answer is that a short blast lasts about one to two seconds because that short, clearly timed burst is the recognized standard for quick maritime communication.
