What action should a vessel take when it enters a situation with restricted visibility?

  1. Increase speed

  2. Stand by for action

  3. Reduce speed and navigate with caution

  4. Change course immediately

The correct answer is: Reduce speed and navigate with caution

When a vessel enters a situation with restricted visibility, the most prudent action is to reduce speed and navigate with caution. This approach is essential for several reasons. Firstly, reducing speed helps to extend the time available for detecting other vessels or obstacles. In restricted visibility, such as fog or heavy rain, the ability to see and identify other vessels is compromised. Slowing down provides the operator more time to react if a situation develops unexpectedly, minimizing the risk of collisions. Secondly, navigating with caution involves staying alert to sounds and other indications of nearby vessels since visual cues may be limited. This includes the use of sound signals as required by the navigation rules, ensuring a safe and responsible passage. Increasing speed or changing course immediately could lead to dangerous situations where other vessels may also be operating without visibility awareness. Rushing may result in a loss of control, while sudden course changes could catch other mariners off guard, increasing the risk of accidents. Remaining prepared for action is also vital, but it does not supersede the importance of reducing speed in enhancing situational awareness and safety in these conditions.
