- Boat/Watercraft Registrations are valid from January 1 through December 31.
- All watercraft with a motor must be registered.
- They MUST be registered in the municipality that you live in as they have excise tax like vehicles.
- Fees vary based on the year, length, horsepower.
What to bring to register your Boat:
You will need to bring your old registration, if you cant find it you can write down or take a pic of the registration number on the boat, or the last sticker on the boat with the year of the sticker.
If you have registered your boat before, you can renew your registration online. There will be a 2.5% fee of the total as charged by the card processing company. Click here to register online
For New Registrations:
Dealer Sale: Bill of sale showing tax paid. Bill of sale should have year, make, model, length, and horsepower of boat, if not we will need that information.
Private Sale: Bill of sale clearly stating the year, make, model, length, horsepower and vin number of the boat. ME registration number if it has one already on it.
Non-Residents: If your boat is going to be in Maine for more than 75 days you must register it in the town where the boat is moored, docked, or located. If you are not going to have it on a lake in Maine for that long you will still need to obtain a lake & river protection sticker provided it has been registered in another state. The cost of a sticker for a non-Maine registered watercraft is $45 and may be purchased online in advance. The stickers are normally mailed within 1-2 business days. Stickers are also available at select agents throughout the state. For more information, please contact MDIFW at (207) 287-8000.
