What action is suggested when a thunderstorm is approaching?

When a thunderstorm is approaching, heading towards the nearest shore is the safest action to take. This allows boaters to seek shelter from hazardous weather conditions, including high winds, lightning, and heavy rain, which can create dangerous situations at sea. Approaching the shore gives boaters a chance to secure their vessel and ensure their safety when the storm conditions become severe.

While continuing to sail as normal may seem like a viable option, it could expose the boat and its occupants to the significant hazards posed by the storm. Turning off all navigation lights is not a safe choice, as lights are crucial for visibility and avoiding collisions, especially in poor weather. Changing course to another waterway may not guarantee safety; it's essential to get to the nearest shore to mitigate the risks associated with the storm.
