Boating is part of life in East Tennessee. From Fort Loudoun Lake and Norris Lake to Melton Hill, Watts Bar, Tellico Lake, and the Tennessee River, people around Knoxville spend summer weekends on the water with friends and family. But the law still applies out on the water.

In Tennessee, you can be arrested for Boating Under the Influence, often called BUI, if law enforcement believes you operated a boat or other covered vessel while impaired by alcohol, marijuana, or drugs. It is not the same charge as DUI, but it is still a criminal offense, and it can carry jail time, fines, and the loss of your boating privileges.

At The Bell Law Firm, PLLC, we take these cases seriously because the same issues that matter in DUI cases often matter on the water: what the officer saw, what testing was done, whether procedures were followed, and whether the State can prove its case.

What Counts as Boating Under the Influence?

A BUI can involve more than a large boat. Depending on the vessel and registration requirements, the law may apply to many types of watercraft commonly used around Knoxville and East Tennessee. That can include allegations involving:

  • Motorboats
  • Personal watercraft, including jet skis
  • Fishing boats
  • Pontoon boats
  • Commercial vessels

The State still has to prove the case. Being on the water, having alcohol on the boat, or being a passenger is not the same as operating a vessel while impaired.

BUI Is Not the Same as Drinking on a Boat

There is a major difference between having alcohol on a boat and operating the boat while impaired.

A passenger drinking on a boat is not the same as the person operating the vessel. The legal focus in a BUI case is whether the accused person was operating a covered vessel and whether they were under the influence or over the legal limit.

That distinction matters, especially in cases where several people were on board, the boat was stopped near a dock, or it is unclear who was actually operating the vessel.

What Are the Penalties for BUI in Tennessee?

For a first-offense BUI, Tennessee law generally treats the charge as a Class A Misdemeanor. Penalties can include:

  • At least 48 consecutive hours in jail
  • Up to 11 months and 29 days in jail
  • A fine between $350 and $1,500
  • Suspension of boating privileges for 12 months

The minimum jail time can increase in certain situations, including cases involving a very high blood alcohol concentration. Penalties can also increase for repeat offenses or when a child is present.

Will a BUI Affect Your Driver’s License?

A BUI is different from a DUI. A Tennessee BUI conviction generally affects your privilege to operate a vessel, not your driver’s license.

That said, the consequences are still serious. A criminal conviction can affect employment, background checks, your reputation, and future criminal exposure if you are charged again.

How BUI Cases Can Be Challenged

A BUI charge is not automatically proven just because an arrest was made. These cases still depend on evidence, procedure, and proof. Important questions may include:

  • Did the officer have a valid reason to stop or board the vessel?
  • Who was actually operating the boat?
  • Was the vessel anchored, docked, or moving?
  • Were field sobriety tests reliable under the conditions?
  • Was a breath, blood, or urine test properly requested and handled?
  • Was the officer’s conclusion supported by the facts?

Boating cases can raise issues that are different from road DUI cases. Wind, waves, sun exposure, heat, dehydration, boat movement, and uneven surfaces can all affect how someone looks or performs during an investigation.
