What action should a boat operator take if they encounter another vessel in poor visibility?

Reducing speed and monitoring your position is the best action for a boat operator to take when encountering another vessel in poor visibility. This approach enhances safety by allowing for better control of the vessel and providing more time to react to the actions of the other vessel. Navigating at a reduced speed increases the operator's ability to observe the surroundings and make necessary adjustments.

In poor visibility conditions, such as fog or heavy rain, the capacity to see and predict the movements of other vessels is significantly compromised. By slowing down, the boat operator is in a better position to avoid collisions, as they can more easily stop or change course if needed.

Keeping an eye on the vessel’s position is also critical to ensure awareness of nearby obstacles or traffic. This vigilance can help the operator maintain a safe course and be ready to take evasive action if another vessel approaches unexpectedly.

The other actions do not contribute positively to safety in poor visibility. For instance, speeding up could lead to a collision by reducing reaction time and increasing stopping distance. Turning off navigation lights is dangerous as it makes the vessel less visible to others, increasing the risk of accidents. While signaling with a horn has its place in alerting others to your presence, it does not replace the need for careful navigation
