If you are operating a power driven vessel that is underway in conditions of restricted visibility, what should you do?

When operating a power-driven vessel in conditions of restricted visibility, sounding a prolonged blast every 2 minutes is an essential practice. This action serves as a signal to other vessels nearby, providing an audible warning of your position and presence. In restricted visibility, such as fog or heavy rain, visual cues are limited, making sound signals crucial for safety.

The regulations governing navigational safety, particularly in poor visibility, emphasize the importance of using sound signals to communicate your location and movements to other mariners. By sounding prolonged blasts at regular intervals, you enhance your visibility to others, reducing the risk of collisions.

Other options may suggest varying approaches, but they do not align with the best practices for safety in restricted visibility. Reducing engine power to idle could risk being overrun by other vessels or impair maneuverability, increasing potential hazards. Increasing speed and navigating quickly is contrary to safe boating practices in low-visibility conditions, as it can diminish your ability to react to unforeseen obstacles. Relying solely on radar for navigation might lead to information overload or misinterpretation without being aware of your surroundings, especially in an environment where sound signals are vital for communication.
