Why is it essential for vessels to maintain a safe speed near areas of restricted visibility?

Answer: B — Because collisions are more likely when both cannot see

Maintaining a safe speed in areas of restricted visibility is crucial because it directly relates to the increased risk of collisions. In such conditions, both vessels and other potential hazards may be difficult to see, making it challenging for mariners to assess the situation accurately. By operating at a reduced speed, a vessel increases its ability to react to unexpected obstacles or changes in the environment. This provides more time to recognize potential dangers and take appropriate action, thus helping to avoid collisions. In addition, operating at a safe speed contributes to better control of the vessel, allowing for safer maneuvers when visibility is compromised. This is particularly important in busy waterways or when other vessels may also be navigating the same area under similar poor visibility conditions. Prioritizing a safe speed is a fundamental practice that enhances navigational safety and minimizes the likelihood of accidents.
