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 D — Change course or speed to avoid vessel "II"

COLREG Rule 18(a)(iii) requires a power-driven vessel to keep out of the way of a vessel engaged in fishing. Since the fishing vessel is not restricted in its ability to maneuver, the power-driven vessel must take early and substantial action to avoid a close-quarters situation.
