No. Boats do not have titles in Maine. The state has never adopted a boat titling system, so no certificate of title is issued regardless of a vessel’s size, value, or engine type. Instead, the Department of Inland Fisheries and Wildlife (MDIFW) registers watercraft annually and issues a certificate of number, and that registration is the closest thing to an ownership document you’ll get from the state.1Maine State Legislature. Maine Code Title 12 – Commissioner’s Powers and Duties Regarding Watercraft
Maine is one of roughly a dozen states that operate this way. The practical consequence is that registration doubles as the state’s ownership record: when you register, your name goes into the MDIFW database as the current owner, and the certificate of number you receive functions as your proof of lawful possession. That works for everyday boating. It gets more complicated the moment money, financing, or a private sale is involved, because there’s no title for a lender to hold or a buyer to demand.
What the Registration Certificate Actually Proves
A Maine registration certificate shows who currently has the boat registered. It does not carry the same legal weight as a car title. There is no state-maintained chain of ownership going back through prior owners, and no title document where a lender’s lien would appear. If you’re used to buying vehicles, this is the mental shift: the paper the seller hands you is a snapshot of the current registration, not proof that the seller actually owns the boat free and clear.
Because of that gap, the burden of establishing ownership sits on the parties to the sale. The state will accept a bill of sale and issue a new registration in the buyer’s name, but it does not verify that the seller had good title to give.
Buying a Boat Without a Title: Protect Yourself With the Bill of Sale
Your most important protection as a buyer is a thorough bill of sale. Insist on one that includes:
- The seller’s full name and address, and yours
- A complete description of the boat: year, make, overall length, and the Hull Identification Number (HIN)
- The engine’s make, model, and horsepower
- The sale price
- The date of sale
- Signatures of both parties
This document becomes your proof of ownership when you go to the town office to register, and it is your primary defense if an ownership dispute surfaces later. For an expensive boat, have the seller sign in front of a notary. The HIN is worth confirming in person against the transom before you sign anything: it’s a 12-character code where the first three characters identify the manufacturer, the next five are the serial, and the final four encode the build date and model year. A mismatch between the HIN on the hull and the HIN on the bill of sale is a reason to walk.
Sellers have obligations too. When ownership transfers, the seller must remove and destroy the validation stickers and notify the MDIFW of the transfer within 10 days. Stickers are not transferable, so as the new owner you start fresh with your own registration.
Check for Liens Before You Pay
This is the step most buyers skip in non-titling states, and it’s where they get burned. Because there’s no title, a lender’s security interest doesn’t appear on any document the seller hands you. Instead, lenders record their interest through Uniform Commercial Code (UCC) filings with the Maine Secretary of State. A boat can look completely clean and still be collateral for someone else’s loan.
Before you hand over money for any used boat of meaningful value, search the UCC database under the seller’s name. The Secretary of State runs a free online search tool that returns active and recently lapsed filings.2Maine Secretary of State. Search for a Uniform Commercial Code Filing If you need a certified result, submit a UCC-11 form by mail, fax, or in person at the Augusta office.
If a search turns up an active filing that lists the boat as collateral, the seller needs to satisfy that debt and obtain a written lien release before the sale closes. A lender holding a valid UCC filing can repossess the boat even after you’ve paid the seller in full and registered it in your name. The search takes a few minutes and costs nothing online.
Federal Documentation: A Real Ownership Record for Larger Boats
If your boat measures at least five net tons, you have another option that Maine’s registration system doesn’t offer on its own: voluntary documentation with the U.S. Coast Guard through the National Vessel Documentation Center. Five net tons is a measurement of internal volume, not length, so it depends on hull design, but many recreational boats around 25 feet and up qualify. Documentation assigns the vessel a federal identification and records it in a national database.
For owners in a non-titling state, the practical draw is the “preferred ship mortgage,” a federally recognized lien recorded with the Coast Guard. It gives lenders a clear priority claim on the vessel, which often makes financing easier to obtain and can improve loan terms. Without documentation, lenders in Maine rely on UCC filings, which some banks consider less protective.
USCG-documented vessels are exempt from Maine’s state registration requirement, though they still owe the annual municipal watercraft excise tax.3Maine Dept of Inland Fisheries and Wildlife. Boating On the hull, you’ll display your federal documentation number in place of a state registration number. For a larger boat or one you plan to finance, documentation is worth exploring as a more formal ownership record than Maine’s registration alone can provide.
Which Boats Still Need to Be Registered
No title doesn’t mean no paperwork. Every motorboat used on Maine waters, of any size and including personal watercraft like jet skis, needs a certificate of number from MDIFW before it launches.3Maine Dept of Inland Fisheries and Wildlife. Boating Operating without a valid certificate is a civil violation with a fine between $200 and $500.4Maine Legislature. Maine Code Title 12 – Certificate of Number, Identification Numbers and Validation Stickers
Non-motorized boats, including canoes, kayaks, rowboats, and sailboats without engines, don’t need registration. USCG-documented vessels are exempt, as are government and military boats, racing boats displaying a valid number from a recognized racing association, and ship’s lifeboats. A boat properly registered in another state can operate in Maine for up to 60 consecutive days without a Maine registration, as long as the out-of-state number is displayed; after that window, or if you change your state of principal use, you need to register in Maine.4Maine Legislature.

New registrations are handled in person at a municipal office that acts as a recreational vehicle agent, or at MDIFW headquarters in Augusta. Bring the bill of sale, the HIN, and a receipt showing you’ve paid the annual watercraft excise tax at your town office; the state won’t issue registration materials without that receipt.5Maine State Legislature. Maine Code Title 36 Section 1504 – Excise Tax Once processed, you’ll walk out with a certificate of number and validation stickers, and that certificate becomes your working ownership document until you sell the boat.
