In visibility-restricted conditions, what is a crucial requirement for safety?

In visibility-restricted conditions, reducing speed is a crucial requirement for safety. When visibility is low, for instance due to fog, rain, or darkness, navigating at a slower speed allows a boater to have more time to assess their surroundings and react appropriately to any potential hazards.

Slower speeds increase reaction time when encountering obstacles, other vessels, or changes in the waterway. It also helps in maintaining better control of the vessel, reducing the impact of sudden maneuvers that can lead to accidents. Furthermore, it allows for a more cautious approach to navigating unfamiliar or potentially dangerous areas, enhancing overall safety for all waterway users.

Conversely, increasing speed in such conditions would heighten the risk of collisions, as the ability to see and respond to obstacles diminishes. Keeping a straight course may not accommodate necessary adjustments to avoid dangers, and using sound signals less frequently contradicts the principles of effective communication on the water, which are vital for safety in reduced visibility scenarios.
