The ability of a teenager to operate a boat without supervision varies by state, as each has its own boating laws and age requirements.
In many states, teenagers who have successfully completed a boater safety course and possess a boater education certificate may be allowed to operate a boat without adult supervision.
However, specific age limits and additional regulations, such as a restriction on the types of boats they can operate or the horsepower of the boat, may apply.
It is essential to check your state's specific boating laws to understand the requirements and limitations for unsupervised boating by minors.
