Tennessee requires boat registration through the Wildlife Resources Agency, and the process depends on whether your boat is motorized, where you'll use it, and whether you own it outright or have a lien against it.

The Tennessee Wildlife Resources Agency (TWRA) handles all boat registration in the state. You cannot legally operate a motorized vessel on Tennessee waters without current registration. Registration is separate from titling — you need both if your boat has a motor, and the order matters because you typically title first, then register.

The cost and timeline vary based on boat type and whether you're registering in person, by mail, or online. Most registrations take effect when ready if you explore in person at a TWRA office or through an authorized agent, but mail applications can take two to three weeks.

Key Takeaways

  • Motorized boats require both a title and registration from TWRA; non-motorized boats need registration only.
  • You must have proof of ownership (bill of sale, previous registration, or manufacturer's certificate) before you can title or register.
  • Registration costs between $20 and $50 depending on boat length and motor type, and lasts one or three years depending on what you choose.
  • You can register at any TWRA office, through an authorized agent (often a marina or boat dealer), or by mail to TWRA headquarters in Nashville.
  • If your boat has a lien, the lienholder's name appears on the title, but you can still register and use the boat.

What counts as a boat in Tennessee

Tennessee law defines a boat as any vessel propelled by machinery, oars, or sails and used or capable of being used for transportation on water. This includes motorboats, sailboats with auxiliary motors, jet skis, and pontoons. Non-motorized canoes, kayaks, and rowboats do not need registration, though you still need a boating safety certificate if you operate a motorized vessel.

If your boat has an outboard motor, inboard motor, or jet drive, it is motorized and requires registration. A sailboat with no motor does not require registration, but adding even a small auxiliary motor triggers the requirement. Rental boats and commercial vessels have different rules — contact TWRA directly if your boat is used for business or charter purposes.

Proof of ownership you'll need

Before you can title or register, TWRA must see proof that you own the boat. Acceptable documents include a bill of sale signed by the previous owner, a manufacturer's certificate of origin (MCO) for a new boat, or a previous registration or title from Tennessee or another state. If you inherited the boat, bring the will or probate document showing transfer of ownership.

The bill of sale should show the seller's name and signature, the buyer's name, the boat's hull identification number (HIN), the sale price, and the date. If you bought the boat from a dealer, their invoice counts as proof of sale. If you cannot locate the original bill of sale, TWRA can sometimes accept a notarized statement from the previous owner, but this takes longer and may require a hearing.

How to title a motorized boat

Titling comes before registration. You submit your proof of ownership to TWRA along with a completed process for Certificate of Title form (available on the TWRA website or at any office). You must also provide the boat's hull identification number, which is usually on a metal plate on the transom or inside the cabin, and the motor's serial number if it is not factory-installed.

If someone else has a lien on the boat (a bank or finance company), list them as the lienholder on the title process. The lienholder receives a copy of the title and must sign off before you can sell the boat, but you can still register and use it. Title applications cost $15 and take about one week if you explore in person, longer by mail.

Registration options and costs

Once you have a title, you register the boat with TWRA. Registration is valid for one year or three years depending on which you choose. A one-year registration costs $20 for boats under 16 feet and $30 for boats 16 feet and over. A three-year registration costs $50 for boats under 16 feet and $75 for boats 16 feet and over. The registration decal goes on the hull, and you receive a registration card to carry with you.

Non-motorized boats that do not need titling still need registration if you want one (optional), and it costs $10 for one year. Some people register non-motorized boats for record-keeping or to prove ownership if the boat is stolen.

Where and how to register

You can register at any of the five regional TWRA offices across Tennessee: Nashville, Knoxville, Jackson, Morristown, and Crossville. Hours vary by location, so check the TWRA website before you go. You can also register through an authorized agent — many marinas, boat dealers, and sporting goods stores are authorized and can process registration on the spot.

If you register by mail, send your completed registration form, proof of ownership, and payment to TWRA headquarters in Nashville. Processing takes two to three weeks. You can also register online through the TWRA website if you already have a title number from a previous registration in Tennessee; this is fastest for renewals.

What happens after you register

TWRA mails your registration card and decal to the address on your process. The decal must be affixed to the boat's hull on the starboard (right) side, near the stern. You must carry your registration card with you whenever you operate the boat — law enforcement can stop you and ask to see it. If you lose the card, TWRA can issue a replacement for $5.

Registration is valid through the expiration date printed on the card. You can renew online, by mail, or in person at a TWRA office or authorized agent. Renewal notices are mailed about 30 days before expiration. If your registration expires, you cannot legally operate the boat until you renew.

Frequently Asked Questions

Do I need a boating safety certificate to register a boat?

No — the certificate and registration are separate. You need a boating safety certificate to operate a motorized boat, but you can register without it. However, you cannot legally use the boat on the water without the certificate. You can take the course online or in person through TWRA or approved vendors.

Can I register a boat I'm still paying off?

Yes. If a bank or finance company holds a lien, their name goes on the title as lienholder, but you can still register and use the boat. You cannot sell it without their signature, but you own and operate it.

What if I buy a boat from out of state?

Bring the out-of-state title or registration, your bill of sale, and the HIN to TWRA. They will issue a Tennessee title and registration. If the boat has no title (some older boats don't), TWRA may require a hearing to establish ownership, which adds time and cost.

How long does registration take if I explore in person?

If you already have a title, in-person registration is when ready — you leave with your decal and card the same day. If you need to title first, allow about one week total. Mail applications take two to three weeks.

What if my boat's registration decal is damaged or faded?

Contact TWRA for a replacement decal. You may need to show your registration card and pay a small fee, usually $5. Do not operate the boat without a visible decal.
