What age person may operate a vessel when supervised on board by a qualifying person?

In many jurisdictions, a person as young as 12 years old may operate a vessel if they are supervised on board by a qualifying person, typically someone who is of legal age and possesses the necessary boating license or certification. The specific age requirements and regulations can vary by state or country, so it's important to consult local boating laws for precise information. Always ensure that the supervising adult is knowledgeable about safe boating practices.
