Frequently Asked Questions

How old do you have to be to rent a boat in New Hampshire?

Under New Hampshire law, you must be 16 to operate a motorized vessel over 25 horsepower without the supervision required for younger operators. RSA 270:30 allows someone under 16 to operate that class only when accompanied by a person at least 18 who holds a valid safe boater education certificate; that adult is liable for resulting personal injury or property damage. RSA 270:74 separately requires ski craft operators to be at least 16. From age 16 onward, anyone operating a motorized vessel over 25 horsepower must hold the boating safety certificate required by RSA 270-D:10. The rental operator sets its own minimum age, so confirm it when booking.

Do you need a boating license in New Hampshire?

Yes. New Hampshire requires operators of motorized vessels over 25 horsepower on public waters to carry a safe boater education certificate; there is no birth date cutoff. Certificates are available at age 16. Anyone under 16 may operate such a boat only when accompanied by someone 18 or older with a valid certificate. The rule covers personal watercraft over 25 horsepower, and ski craft operators must be at least 16. Renters are not exempt, but someone 16 or older may pass an approved exam for a 14 Day Temporary Certificate, which can be used only once. Other accepted credentials are another state's NASBLA certificate, a US Power Squadron or Coast Guard Auxiliary card, and Coast Guard or New Hampshire commercial licenses. New Hampshire State Police Marine Patrol administers the program.

What are the best places to go boating in New Hampshire?

The best places to boat in New Hampshire span four distinct settings: Lake Winnipesaukee, Great Bay, the Pemigewasset River and the Connecticut Lakes. In the Lakes Region, Winnipesaukee is the state’s largest lake and offers broad water for boating and fishing. On the Seacoast, Great Bay provides saltwater estuary paddling near Portsmouth. The Pemigewasset has both serene stretches and moving water for river trips. Far north in the Great North Woods, the four Connecticut Lakes offer remote boating, kayaking, canoeing and wildlife viewing amid forests and mountains.
