All motorboats used on Maine waters (with Maine as the state of principal use) must be registered with the State. If your boat is registered in another state and you wish to use the vessel here in Maine, you will need to purchase a $19 Mil Foil Sticker.
Registrations are issued for the calendar year and expire December 31st. Registration fees and excise tax vary depending on the length, model year, use and horsepower.
Owners of new boats need to bring in a sales receipt showing the serial number, and will be required to pay sales tax.
For more information on boating laws and facilities, visit the Maine Department of Inland Fisheries and Wildlife at 284 State St. in Augusta or check out their website.
