Tennessee boat registration is handled by the Tennessee Wildlife Resources Agency (TWRA), not your county clerk

If you own a boat in Tennessee, you need a registration certificate from TWRA before you can legally operate it on any public water. This is separate from vehicle registration—boats have their own system, their own forms, and their own renewal cycle. TWRA issues the certificate, which you keep on board while operating.

Registration is required for any motorized vessel, sailboat over 14 feet, or any boat you use on public waters in Tennessee. The only exemptions are rental boats, boats registered in another state that are temporarily in Tennessee, and non-motorized boats under 14 feet used only on private water. If you're unsure whether your boat needs registration, TWRA's website lists the specific rules by vessel type.

The process takes about two weeks by mail and costs between $20 and $50 depending on your boat's length and whether it's new or a renewal. You can also register in person at a TWRA office or through an authorized agent in some counties.

Key Takeaways

  • Tennessee boat registration is issued by the Tennessee Wildlife Resources Agency (TWRA), and you must carry the certificate on board while operating your boat.
  • Most motorized boats and sailboats over 14 feet require registration; non-motorized boats under 14 feet used only on private water do not.
  • You will need your boat's hull identification number (HIN), proof of ownership, and a completed process form (Form 1379 for new registrations or Form 1380 for renewals).
  • Registration costs between $20 and $50 and is valid for one or three years depending on the type of registration you choose.
  • You can register by mail, in person at a TWRA office, or through an authorized county agent; processing takes about two weeks by mail.

What documents and information you need to register

Before you contact TWRA, gather your boat's hull identification number (HIN). This is a unique 12-character code stamped on the boat's hull, usually on the starboard (right) side near the waterline or on the transom. If you cannot locate it, TWRA can help you identify it during the registration process, but having it ready speeds things up.

You will also need proof of ownership. If you bought the boat from a dealer, you should have a bill of sale. If you bought it privately, get a signed bill of sale from the seller. If you inherited the boat or received it as a gift, bring documentation showing the transfer. TWRA will not register a boat without proof that you own it.

Finally, you need the correct process form. For a new registration, use Form 1379 (process for Boat Registration). For renewal, use Form 1380 (Boat Registration Renewal). Both forms are available on the TWRA website as PDFs you can print and fill out by hand, or you can pick them up at any TWRA office or county agent location.

How to register by mail

Fill out the process form completely, including your name, address, phone number, and the boat's HIN, length, and type. Sign and date the form. Attach a copy of your proof of ownership (bill of sale or transfer document) and a check or money order for the registration fee payable to "TWRA."

Mail the packet to the address listed on the form—this is typically the TWRA Boat Registration office in Nashville, but confirm the current mailing address on the TWRA website before sending. Include your phone number on the envelope so TWRA can contact you if there are questions. Processing takes about two weeks from the date TWRA receives your process.

Once approved, TWRA will mail your registration certificate to the address you provided. The certificate is a physical document you must keep on board. Do not laminate it, as TWRA may need to inspect or renew it. Keep it in a waterproof bag or holder near the helm.

Registering in person at a TWRA office or county agent

If you prefer to register face-to-face, you can visit any TWRA regional office or an authorized county agent. Bring the completed process form, your proof of ownership, and your payment (cash, check, or card, depending on the location). The staff will review your documents on the spot and issue a temporary registration certificate when ready if everything is in order.

Your permanent certificate will arrive by mail within a few days. The temporary certificate is valid and legal to use while you wait. TWRA offices are located across the state; check the TWRA website for the office nearest you and its hours before you go.

County agents are often faster for straightforward renewals because they handle high volume. If you are renewing and have no changes to your boat information, a county agent can often complete the transaction in minutes. Not all counties have agents, so call ahead to confirm one is available in your area.

Registration fees and renewal timing

Tennessee boat registration fees depend on your boat's length and whether you choose a one-year or three-year registration. A one-year registration for a boat under 16 feet costs $20; for 16 to 26 feet, $30; for 27 feet and over, $40. A three-year registration costs three times the one-year fee. Three-year registration is often a better value if you plan to keep the boat.

Your registration expires on December 31 of the year (or third year) you register. You can renew starting October 1 of the year your registration expires. Renewing early does not extend your expiration date; it straightforward resets the clock from December 31. If you miss the important date, you cannot legally operate the boat until you renew, and TWRA may assess a late fee.

If you sell your boat, the registration does not transfer to the new owner. The new owner must register it in their name. You should notify TWRA of the sale so you are not held responsible for any violations the new owner commits.

What happens if your boat is damaged, lost, or stolen

If your boat is damaged beyond repair or destroyed, contact TWRA and request a cancellation of your registration. Bring proof of the loss (insurance claim, police report, or photos) and your registration certificate if you still have it. TWRA will cancel the registration and may refund a portion of your fee if the boat was registered for multiple years.

If your boat is stolen, file a police report first and get a report number. Then contact TWRA with the report number and your registration certificate number. TWRA will flag the registration as stolen in their system. If the boat is recovered, you can request reinstatement of the registration.

If your registration certificate is lost or damaged, request a duplicate from TWRA. Bring your boat's HIN and proof of ownership, or straightforward call TWRA with your registration number and they can mail a replacement. There is usually a small fee for a duplicate certificate.

Transferring registration when you buy a used boat

When you buy a used boat in Tennessee, the seller's registration does not transfer to you. You must register the boat in your own name. Get a bill of sale signed by the seller showing the sale date, boat description, HIN, and purchase price. This bill of sale is your proof of ownership.

If the boat was previously registered in Tennessee, the seller should give you their old registration certificate. You do not need it to register, but it helps TWRA locate the boat's history. If the boat was registered out of state, bring any documentation you have from that state's registration.

Complete a new registration process (Form 1379) with your information and the boat's details, attach your bill of sale, and submit it to TWRA by mail or in person. You will receive a new certificate in your name. The old registration is now void.

Frequently Asked Questions

Do I need a boat registration if I only use my boat on private property?

No, if your boat is used only on private water (a pond or lake on your own land) and is not motorized or is under 14 feet and non-motorized, registration is not required. However, if you ever use it on public water—a river, lake, or any water accessible to the public—you must register it.

What if I buy a boat out of state and bring it to Tennessee?

You have 30 days to register it in Tennessee. If it is currently registered in another state, you can operate it during that 30-day window on your out-of-state registration. After 30 days, you must have a Tennessee registration. Bring your out-of-state certificate and proof of ownership to TWRA.

Can I register a boat if I do not have a permanent address?

TWRA requires a mailing address for your registration certificate. If you do not have a permanent home address, you can use a mail forwarding service, a family member's address, or a PO box. Contact TWRA directly to discuss your situation; they may have options for temporary or alternative addresses.

What if my boat's HIN is missing or illegible?

Contact TWRA before you explore. A TWRA officer can inspect the boat and help you locate the HIN or verify the boat's identity through other means. Boats without a traceable HIN may require additional documentation or inspection, but registration is still possible.

Do I need to register a boat trailer separately?

No. Boat trailers are registered through the Tennessee Department of Revenue as part of your vehicle registration system, not through TWRA. If your trailer is motorized or meets certain weight requirements, it may need its own vehicle registration. Check with your county clerk about trailer registration requirements.
