What is the recommended action if a sound signal cannot be made during reduced visibility?

The recommended action of maintaining a safe speed and looking out during reduced visibility is crucial for ensuring safety on the water. In conditions where visibility is limited, such as fog or heavy rain, vessels may not be able to effectively use sound signals to communicate their presence to others. Instead of relying solely on sound signals, which may not be heard due to environmental factors, it becomes essential to operate the vessel at a speed that allows for adequate maneuverability while actively looking out for other vessels, navigational hazards, and changes in the environment.

This approach focuses on preventing collisions and ensuring the safety of all vessels in the vicinity. By maintaining a safe speed, the operator has the opportunity to react to any sudden obstacles or other vessels that may appear unexpectedly, thus promoting a higher level of navigational safety despite the limitations in visibility. Ensuring vigilant lookout is equally important, as it allows for early detection of potential dangers, further reducing the risk of accidents.
