Boat Laws in Tennessee (2026): Rules Every Boater Must Follow

Tennessee has some of the best water in the South. From the Tennessee River to Dale Hollow Lake, people come from everywhere to get out on the water. But before you fire up the engine, you need to know the rules.

Honestly, most people don’t realize how many boating laws Tennessee has. Some are simple. Others can land you in serious legal trouble. Let’s break it all down so you’re ready before you hit the water.

What Are Tennessee Boating Laws?

Tennessee boating laws are rules set by the state that tell you how to safely and legally operate a boat. They cover everything from who can drive a boat to what safety gear you must carry. The Tennessee Wildlife Resources Agency, called the TWRA, is the main agency that enforces these laws.

These laws exist to protect everyone on the water. Tennessee has over 50 rivers and countless lakes. That’s a lot of boats sharing the same space. Rules help keep things safe.

Do You Need a Boating License in Tennessee?

Okay, this one is important. Tennessee doesn’t call it a “license” exactly. But you may still need to pass a safety exam.

Any Tennessee resident born after January 1, 1989, must show a TWRA-issued wallet Boating Safety Education Certificate as proof of passing the TWRA Boating Safety exam. You need this card to operate a motorized boat with more than 8.5 horsepower.

Sound complicated? It’s actually not. Individuals born after 1989 are required to complete a boater safety course to obtain a Boating Safety Education Certificate. Sailboats and all other boats powered by an engine of less than 8.5 horsepower do not need a certificate.

The good news? Your official boating license will be good for life. You only have to pass it once. Pretty straightforward.

Vessel operators who are required to have a Boater Education Card must carry the card on board the vessel and have it available for inspection by an enforcement officer. Don’t leave it at home.

How to Get Your Boating Safety Card

You’re gonna want to get this done before summer hits. Here’s the process.

You must first purchase a Boating Safety Exam Permit from the TWRA GoOutdoorsTennessee website or any business that sells hunting and fishing licenses, like Walmart, sporting goods stores, bait stores, or marinas. You will need your Social Security number and driver’s license.

You can then take the Boating Safety Exam online or in an instructor-led course. If you fail, no big deal. You can retake it as many times as you need.

Out-of-state boaters, listen up. Out-of-state residents born after January 1, 1989, must show proof of completing a National Association of State Boating Law Administrators approved boating safety course. Tennessee accepts these from other states. Yep, that’s all you need.

Registering Your Boat in Tennessee

Wondering if your boat needs to be registered? Most likely, yes.

Tennessee law requires that all mechanically powered vessels, including federally documented recreational vessels, and all sailboats that are principally used in Tennessee must be registered. This includes electric trolling motors. It does not include boats powered only by oars or paddles.

The registration process requires proof of ownership and payment of applicable fees, with renewal periods ranging from one to three years. Unlike some states, Tennessee does not require boats to be titled, though proof of ownership must be maintained.

You can register your boat through the TWRA online portal called GoOutdoorsTennessee or at a local TWRA regional office. Once you’re registered, you get a temporary registration good for 60 days while your official paperwork processes.

Life Jacket Rules in Tennessee

Hold on, this part is really important. Life jacket rules could literally save your life.

All boats, including canoes and kayaks, must be equipped with one wearable life jacket for each person on board and for each person being towed on waterskis. Boats 16 feet in length or over, except canoes and kayaks, must also be equipped with one Type IV throwable personal flotation device.

Children under the age of 12 must wear a personal flotation device, also referred to as a life jacket, while on an open deck of a recreational boat in Tennessee. Exceptions arise only where the boat is anchored, moored, or aground.

Any person operating, riding on, or being towed by a personal watercraft is required to wear a Coast Guard-approved Type I, II, or III life jacket. Inflatable life jackets are not permitted on personal watercraft.

There’s one more rule people often miss. When operating a boat near a dam, each person on board is required to wear a Coast Guard-approved life jacket. This one catches a lot of people off guard.

Age Rules for Operating a Boat

Confused about who can drive? Let me break it down.

Children under the age of 12 are not permitted to operate a boat powered by an engine of more than 8.5 horsepower unless they are accompanied by someone over the age of 18.

Personal watercraft operators are required to be at least 12 years of age to operate a PWC without an adult supervisor on board. A personal watercraft means a jet ski or similar watercraft.

There’s actually a bill moving through the Tennessee legislature right now. It proposes increasing the minimum age from 12 to 16 for operating a personal watercraft without direct adult supervision. This hasn’t become law yet, but it’s worth keeping an eye on.

Alcohol and Boating: The BUI Law

Now here’s where things get very serious. Tennessee takes drinking and boating just as seriously as drinking and driving.

A boat operator cannot have a blood alcohol concentration of 0.08% or higher, which is the same legal limit applied to drivers on roadways. The restriction exists because boat operators must stay sober enough to safely control the boat at all times.

Wait, it gets better. Passengers can drink. Passengers over the age of 21 are permitted to drink while on a boat in Tennessee. But the operator? Absolutely not.

Beginning July 1, 2023, there is no longer a meaningful difference between Boating Under the Influence and Driving Under the Influence in Tennessee. Courts now use the same sentencing for BUI cases as DUI cases. Think of it like a DUI, but on water. Same seriousness. Same consequences.

Tennessee applies its BUI laws to a variety of vessels beyond traditional boats, including any other powered vessel. Sun, wind, noise, and motion on the water actually intensify the effects of alcohol too. So even one or two drinks hits harder out on the lake.

Most people assume BUI is less serious than DUI. They find out the hard way. Don’t be one of them.

BUI Penalties in Tennessee

So what happens if you’re caught boating under the influence? You’re not going to like this.

A first-offense BUI generally carries up to 11 months and 29 days in jail, $250 to $2,500 in fines, and a maximum one-year boating privilege suspension.

If it’s not your first offense, you can expect harsher penalties under TN Code section 69-9-219. These include a mandatory minimum of 48 hours and up to almost one year in jail, possible suspension of boating privileges, probation or community service, and at least 120 days to nearly one year of jail time for more serious cases.

Under Nicholas’s Law, passed in 2023, prior BUI convictions are now treated the same as prior DUIs for sentencing and penalties. Law enforcement can also request search warrants for blood tests from BUI suspects.

Honestly, the penalties are steep. And there were more than 130 BUI arrests made in Tennessee in 2024. Officers are actively watching. This is no joke.

Speed and Navigation Rules

Tennessee has specific rules about how fast you can go and how close you can get to other boats and objects.

Boats must not come closer than 50 feet to a diver’s flag and must operate at a slow no-wake speed within 200 feet of the flag. A diver’s flag means someone is underwater nearby.

Boaters must slow to no-wake speed within 100 feet of a law enforcement vessel that is displaying flashing blue lights. This is similar to Tennessee’s Move Over law on highways. It went into effect in 2018.

The noise level of a motorized boat may not exceed 86 decibels at 50 feet or more. The engines of all motorized boats must have an effective muffling system.

Protecting Tennessee Waterways

Here’s something a lot of boaters don’t think about. You’re responsible for the health of the waterway too.

Discharging untreated sewage into public water is prohibited. It is illegal to operate a vessel that is capable of discharging untreated sewage.

Tennessee has aquatic invasive species laws, requiring boaters to drain all water from boats and remove vegetation before transporting their vessels. Invasive species travel from lake to lake on boats and equipment. This law helps stop that.

Personally, I think this law makes total sense. Nobody wants their favorite lake taken over by invasive plants or fish.

New Laws at Public Boat Ramps (2025)

You might not know about this one. A new law took effect in July 2025.

New regulations prohibit individuals from engaging in activities that interfere with or inhibit the proper use of public boat launches and marinas. This includes fishing or swimming in a manner that blocks access to boat launches, prevents the normal launching and retrieval of boats, or causes damage to docks, boats, or marina infrastructure.

So if you’re hanging out at the boat ramp and blocking traffic, you can now face penalties. It’s more common than you think, and now it’s officially illegal.

How to Report a Boating Violation

Wondering if this applies to you or someone you see on the water? Here’s what you can do.

If you see a boating violation happening, you can report it to the TWRA. To report a hunting, fishing, or boating violation, call the numbers located on the TWRA Law Enforcement page, 7:00 a.m. until 12:00 midnight, seven days a week.

You can also call the TWRA main line at (615) 781-6500 or visit tn.gov/twra for more information. Don’t worry, you can report anonymously in many cases.
