What should you do if visibility is limited due to fog?

When visibility is limited due to fog, it is crucial to reduce speed to avoid collisions. Navigating at a slower pace gives the boat operator more time to react to potential hazards, such as other boats, buoys, and land formations that may not be easily seen. Slowing down also allows for better control of the vessel in unexpected situations, ensuring safety for everyone on board and nearby vessels.

Anchoring and waiting for the fog to clear could be a safe option, but it may not be feasible in all situations, especially if there are other boats in the area that might not see you. Speeding up is dangerous as it increases the risk of colliding with unseen obstacles. Maintaining usual navigation practices without adjusting for the significantly reduced visibility is also risky and does not take into account the need for heightened caution. In fog, the priority should always be safety, which is best achieved by reducing speed.
