Question 411 Rules of the Road

The correct answer is D) Change course or speed to avoid vessel "II". The International Regulations for Preventing Collisions at Sea (COLREGS) require a power-driven vessel to take early and substantial action to avoid collision with a vessel engaged in fishing within 1/2 a mile, as described in the scenario. The power-driven vessel "I" must maneuver to keep well clear of the fishing vessel "II" and avoid a collision, rather than relying on the fishing vessel to take action. Options A, B, and C are incorrect because they do not involve the necessary maneuvering to avoid the collision risk.
