Tennessee boat registration is handled by the Tennessee Wildlife Resources Agency (TWRA), and you'll need to register any motorized vessel or sailboat over 14 feet before operating it on state waters.

Registration happens through your county clerk's office or online through the TWRA website. The process takes about two weeks by mail or a few days online. You'll need proof of ownership (a bill of sale or manufacturer's certificate), proof of your Social Security number, and a completed process form. The cost varies based on boat length and type, but most registrations run between $30 and $100 for the first year.

Once registered, your boat receives a hull number and registration decals that must be displayed on both sides of the vessel. Registration is valid for three years, and renewal notices arrive by mail about 60 days before expiration. If you're buying a used boat, the previous owner's registration transfers to you once you complete the paperwork with the new ownership information.

What boats require registration in Tennessee

Any motorized vessel must be registered, regardless of size. This includes boats with outboard motors, inboard motors, jet skis, and pontoons. Sailboats over 14 feet also require registration. The 14-foot rule applies only to sailboats — motorized boats of any size need to be registered.

Boats that do not require registration include non-motorized sailboats under 14 feet, canoes, kayaks, rowboats, and inflatable boats without motors. If you're unsure whether your specific vessel needs registration, the TWRA office can tell you based on a description of the boat and its motor.

How to register online through TWRA

The fastest route is the TWRA online registration system at the agency's website. You'll create an account, enter your boat information (hull identification number, length, type, and motor details), and upload a photo of your boat's hull number. The system accepts payment by credit or debit card. Once approved, you receive your registration number and can print temporary decals when ready while permanent decals arrive by mail within five to seven business days.

Online registration takes about 15 minutes to complete and costs the same as in-person registration. You'll need your Social Security number, proof of ownership (bill of sale or manufacturer's certificate), and the boat's hull identification number. If your boat doesn't have a hull number, TWRA can assign one during the registration process.

How to register in person at your county clerk's office

Visit your county clerk's office with your completed process form (available on the TWRA website or at the clerk's office), proof of ownership, and proof of your Social Security number. Bring a photo ID as well. The clerk will process your registration on the spot and issue your registration number and decals when ready. This route works well if you prefer to handle everything face-to-face or if you don't have online access.

Processing takes a few minutes, and you walk out with your decals ready to install. The cost is the same whether you register online or in person. If you're registering a used boat, bring the previous owner's registration certificate along with your bill of sale showing the transfer of ownership.

Registration costs and what affects the price

First-year registration fees are based on boat length. Boats under 16 feet typically cost around $30 to $40, boats 16 to 26 feet run $50 to $70, and boats over 26 feet cost $80 to $100 or more. These are approximate ranges — the exact fee depends on your specific boat's length and type. Commercial vessels and rental boats have different fee structures.

Renewal fees for years two and three are usually lower than the first-year fee. If you register late (after your registration expires), you may owe a late fee in addition to the renewal cost. The TWRA website has a fee calculator where you can enter your boat's length and type to see the exact cost before you register.

Installing and displaying registration decals

Your registration decals must be placed on both sides of the boat's hull, near the waterline or in a location clearly visible from the water. The decals show your registration number and are required by law. If you register online, print the temporary decals and install them when ready — they're valid until your permanent decals arrive. Permanent decals are more durable and should replace the temporary ones once they arrive.

If a decal becomes damaged, faded, or illegible, contact TWRA to request a replacement. Operating a boat without visible registration decals can result in a citation. Keep your registration certificate on board — law enforcement may ask to see it during a water safety check.

Renewing your boat registration

Registration is valid for three years from the date of issue. About 60 days before expiration, you'll receive a renewal notice by mail. You can renew online through TWRA or at your county clerk's office using the same process as initial registration. Renewing online takes about 10 minutes and new decals arrive within a week.

If you miss the expiration date, you can still renew, but you'll owe a late fee. Operating an expired registration is a violation and can result in a citation. If your boat's registration has been expired for more than a year, you may need to re-register rather than renew — contact TWRA to confirm the process for your situation.

Transferring registration when you sell or buy a boat

If you're buying a used boat, the previous owner's registration does not automatically transfer to you. You'll need to complete a new registration in your name using the bill of sale as proof of ownership. Bring the previous registration certificate, the bill of sale, and your proof of Social Security number to your county clerk's office or register online through TWRA.

If you're selling a boat, notify TWRA of the sale so your name is removed from the registration. The new owner must register the boat in their name before operating it. Some sellers and buyers handle this at closing; others complete it separately. Either way, the boat cannot legally be operated under the old registration once ownership changes.

Frequently Asked Questions

Do I need to register a boat I only use on private property?

If the boat stays on private property and never enters public waters, registration is not required. However, once you launch it on any public waterway in Tennessee — including rivers, lakes, and reservoirs — it must be registered. If you're unsure whether a body of water is public, contact TWRA.

What if my boat doesn't have a hull identification number?

TWRA can assign a hull number during registration if your boat doesn't have one. This is common with older or homemade boats. You'll need to bring the boat or provide detailed photos so TWRA can assign and mark the number. Once assigned, the number becomes your boat's permanent identifier.

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

Yes, you can register a boat with a lien on it. The lienholder's name may appear on the registration certificate, but this doesn't prevent you from registering or operating the boat. Bring proof of ownership (bill of sale or manufacturer's certificate) along with any loan documents showing the lien.

What happens if I lose my registration certificate?

Contact TWRA or your county clerk's office to request a replacement certificate. You'll need to provide your boat's registration number and proof of identity. A replacement certificate typically arrives within one to two weeks. You can continue operating the boat while waiting for the replacement.

Do I need to register a boat I'm importing from another state?

Yes, any boat operated on Tennessee waters must be registered with TWRA, even if it was previously registered in another state. Bring your out-of-state registration certificate, proof of ownership, and proof of your Social Security number to your county clerk's office or register online. Your previous registration does not transfer — you'll receive a new Tennessee registration number.
