Massachusetts sets 12 as the minimum age to operate a motorboat without direct adult supervision, if the operator satisfies the applicable boater safety certificate rule; personal watercraft operators must be at least 16. A child under 12 may operate a motorboat only while accompanied on board and directly supervised by a certificate holder at least 18. Direct supervision requires visual contact and verbal communication at all times while underway.

Certification is phased by birth date under Massachusetts General Laws chapter 90B, section 9E: people born after January 1, 1989, have been covered since April 1, 2026; those born on or before that date must comply by April 1, 2028. Rental operators set their own minimums, so confirm when booking.

Yes. Massachusetts requires a boater safety certificate, rather than a boating license, for motorboat and personal watercraft operators born after January 1, 1989; those born on or before that date must comply by April 1, 2028. Personal watercraft operators must be at least 16. Children under 12 may operate a motorboat only under direct onboard supervision by a certified adult age 18 or older.

Rental customers are not generally exempt, and temporary rental certificates are only under consideration for lower power boats. Exemptions include direct supervision, qualifying nonresident certificates, merchant mariner credentials, certain military and commercial fishing operators, and recent boat buyers carrying a temporary certificate. Massachusetts Environmental Police administers the program.

From Boston, you can boat Boston Inner Harbor, the Charles River Basin, Dorchester Bay, Spectacle Island and Nantasket Roads. Boston Inner Harbor follows the marked Main Channel past the city’s working waterfront; DCR lists a public landing on Day Boulevard. The Charles is popular with small craft above its dams and connects to the harbor through navigation locks, with put-ins at Clarendon Street, the Hatch Shell and the Charles River Dam. Dorchester Bay has extensive shallow flats near its channel. Spectacle Island has a marina and ferry dock. Farther out, The Narrows leads to Nantasket Roads, an anchorage with scattered shoals and rocks.

From Boston, boaters make Boston Harbor day trips to Spectacle, Georges and Peddocks islands. Spectacle draws crews for beaches, hiking trails and skyline views; Georges for Fort Warren and harbor views; Peddocks for shoreline, trails, open spaces and military and cultural history. All three have reservable park moorings, and the park also permits anchoring off islands at the boater’s own risk.
