What action should a boater take if they become lost?

When a boater becomes lost, staying calm and assessing the situation is crucial for ensuring safety. Instead of panicking or racing in different directions, which can lead to accidents or worsening the situation, a boater should take a moment to gather their thoughts and analyze their available navigation tools. This may include a map, compass, GPS device, or any other equipment that can provide direction or help determine their location.

If after assessing their situation they feel it's necessary, signaling for help is a wise course of action. This can involve using flares, sound signals, or even radio communication to reach nearby boats or rescue services. Staying in one place can also help make it easier for rescuers to find the boater.

Turning off all electronics, while perhaps a means to conserve battery, removes potentially vital tools for navigation or communication. Swimming to the nearest shore can also be unsafe due to various factors including current conditions, distance, and the unknown nature of the shoreline. Therefore, the recommended action is to remain calm, utilize navigation tools, and signal for help when needed, making option B the best choice.
