At a Glance
Registration
All motorboats of any size, including airmobiles and personal watercraft, must be registered in Maine. Residents register through their town office and pay excise tax to their town of residence. Non-residents register through the town where the watercraft is primarily moored, docked, or located. Registrations are valid through December 31st of the year issued. A portion of each inland boat registration fee goes to the Lake and River Protection Program. Racing boats with valid racing association numbers are exempt. Non-Maine registered watercraft properly registered in another state do not need Maine registration if not kept in Maine for more than 60 consecutive days, but must still have a Lake and River Protection Sticker.
Safety Education
Maine enforces boater education requirements for operators of motorboats. The Maine Department of Inland Fisheries and Wildlife provides information on boating safety. Online boating safety courses are available for certification.
Safety Equipment
All vessels must carry required safety equipment as specified by Maine and US Coast Guard regulations. Specific equipment requirements vary by vessel type and length.
Boating Laws
All boaters must follow Maine boating laws including navigation rules, speed regulations, and operating requirements. Boating under the influence of alcohol or drugs is prohibited.

Invasive Species
Boaters must help protect Maine waters from aquatic invasive species. A Lake and River Protection sticker is required. Boaters should clean, drain, and dry their vessels before launching. It is illegal to launch with aquatic plants attached to the vessel or trailer.
