BOTH INTERNATIONAL & INLAND A power-driven vessel is underway and fishing with trolling lines. Which statement is TRUE?

Correct Answer: Option B — it must keep out of the way of sailing vessels

Rule 18(a)(iii) dictates that a power-driven vessel underway shall keep out of the way of a sailing vessel. Even when engaged in fishing with trolling lines, a vessel is not considered 'engaged in fishing' under Rule 3, and therefore must yield to sailing vessels as a power-driven vessel.
