BOTH INTERNATIONAL & INLAND Vessels I and II are underway as shown in illustration D033RR below. Vessel I is a sailing vessel with the wind dead aft. Vessel II is a power- driven vessel trawling. Which statement is TRUE?

Correct Answer: Option A — Vessel I is to keep clear because the other vessel is fishing.

Rule 18 dictates that a sailing vessel must keep out of the way of a vessel engaged in fishing, regardless of the sailing vessel's wind orientation or relative positioning.
