How old do you have to be to operate a boat with a certificate?

The age requirement to operate a boat with a certificate varies by location. In many places, individuals must be at least 16 years old to operate a motorized vessel, while those younger may be allowed to operate under certain conditions or with adult supervision. It's essential to check local regulations, as they can differ significantly by state or country. Additionally, some regions may require completion of a boating safety course regardless of age.
