BOTH INTERNATIONAL & INLAND When a vessel signals her distress by means of a gun or other explosive signal, which firing intervals should be used?

A Once every 10 minutes
B Once an hour
C Once every minute
D Once every 3 minutes
AI Explanation

The correct answer is C) Once every minute. When a vessel signals distress by means of a gun or other explosive signal, the firing intervals should be once every minute. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which specify that distress signals using gun or other explosive signals should be fired at intervals of about a minute. The other options are incorrect because a firing interval of once every 10 minutes (A) or once an hour (B) would be too infrequent to effectively signal distress, while once every 3 minutes (D) would be more frequent than the COLREGS requirement.
