In restricted visibility, which of the following is a recommended practice?

• A. Increase speed to pass others quickly.
• B. Use radar and communications as needed to maintain safe separation.
• C. Rely only on visual cues.
• D. Stop and wait for others to change course.

Answer: (B)

In restricted visibility you can’t rely on sight alone, so using radar and communications to maintain safe separation is the best practice. Radar lets you detect and track other vessels that aren’t visible, giving you a clearer picture of traffic and helping you judge safe passing distances. Open, regular communications (VHF or other) with other vessels clarifies intentions and coordinates maneuvers, reducing the risk of collision.

Relying only on visual cues isn’t reliable when visibility is poor, and speeding up to pass others quickly increases the chance of an overtake or crossing collision. Stopping and waiting is not a practical default; you should reduce speed and proceed with caution, using all available tools to stay out of danger.
