INTERNATIONAL ONLY You are on a power-driven vessel "I" as shown in illustration D036RR below. Vessel "II" is a vessel engaged in fishing within 1/2 a mile of your vessel. Which action should you take?

Correct Answer: Option B — Change course or speed to avoid vessel "II".

COLREG Rule 18 mandates that a power-driven vessel underway must keep out of the way of a vessel engaged in fishing. When encountering vessel II within close proximity, you must take positive and timely action to alter course or speed.
