Maine Boater Qualifications
If you're between 16 and 18 years old, the Maine Department of Inland Fisheries and Wildlife requires you to complete a boating safety course if you want to operate a personal watercraft unsupervised. Without a boating safety certificate, you'll need to be accompanied by somebody who's at least 18 years old to operate personal watercraft on Maine waters. There may be state age restrictions regarding piloting a boat, check with IFW for more details.
You can choose to complete the boating education requirement:
