In fog with other vessels detected by radar, which statement is TRUE regarding maneuvering?

• A. You should maintain course and speed
• B. You should stop immediately
• C. You should maneuver in ample time if a close-quarters situation is developing
• D. You should accelerate to pass quickly

Answer: (C)

In fog you rely on radar to spot other vessels and gauge how close you might come, so the safest practice is to act early if a potential close-quarters situation could develop. Maneuvering in ample time means adjusting your course and/or speed well before proximity becomes critical, creating space and reducing risk for both vessels. This proactive approach aligns with the need to avoid last‑minute or sudden changes that can cause confusion or collision. Stopping suddenly, rushing ahead, or sticking to your current path don’t reliably reduce risk in limited visibility and can actually worsen the situation.
