BOTH INTERNATIONAL & INLAND What is TRUE when operating in fog and other vessels are detected by radar?
AI Explanation
The correct answer is C) You should maneuver in ample time if a close-quarters situation is developing.
This is the correct answer because the International Regulations for Preventing Collisions at Sea (COLREGS) require that vessels take early and substantial action to avoid a close-quarters situation when operating in restricted visibility, such as fog. Waiting until the last minute to take action increases the risk of collision. Maneuvering in ample time allows you to make a safe and controlled change in course or speed to avoid a dangerous situation.
The other answer choices are incorrect because: A) Determining contact courses and speeds at 6-minute intervals is not a requirement, B) A port change is not the automatic maneuver, and D) Long-range scanning cannot guarantee detection of all vessels within radar range.
