Yes — Maine requires an MDIFW-approved boater safety and education course for younger operators, and the exact cutoff depends on the vessel. A person born on or after January 1, 1999 must be at least 12 and have completed the course to operate a recreational motorboat over 25 horsepower. A person born after January 1, 1999 must be at least 16 and have completed the course to operate a personal watercraft (PWC), such as a jet ski. Both rules apply on Maine's inland waters and territorial sea.
The requirement took effect January 1, 2024; operators born before these cutoffs are grandfathered and exempt, and motorboats of 25 horsepower or less are not subject to the education requirement. The certificate is earned through a NASBLA-approved course — online or in person, with free and low-cost options through MDIFW — and does not expire. A safety course is recommended for every boater, even where it isn't legally required.
