State Boating Under the Influence Laws

Operating a motor vehicle after drug or alcohol consumption is dangerous and potentially deadly. But the dangers don't stop on the road. This also includes sailboats, yachts, motorboats, water skis, and other personal watercraft. You could face arrest for boating under the influence (BUI).

Federal law prohibits anyone from operating a watercraft while under the influence of alcohol, drugs, or a combination, with a blood alcohol content (BAC) legal limit of 0.08%.

The U.S. Coast Guard reports that one-third of recreational boating fatalities involve a drunk operator. Roughly half of boating accidents involve intoxication. Being out on the water, with the bright sun and the motion of the watercraft, can speed up alcohol's effects.

A rise in alcohol- and drug-related boating injuries and fatalities prompted state legislatures to enact BUI laws. As with driving under the influence (DUI), legal penalties can range from hefty fines to losing your boating license to even prison time for causing death or serious injury.

This table outlines the blood alcohol concentration (BAC) limits under state and other laws for boating under the influence.

Boating Under the Influence

Law enforcement, the Coast Guard, park rangers, and game wardens patrol waters to ensure the area is safe. They may stop you if they reasonably suspect you are under the influence. They can also conduct random checks or set up sobriety checkpoints.

If your boat gets stopped, the law enforcement officer or the authority responsible for boating safety will ask you to submit to field sobriety tests and chemical tests to determine impairment. Chemical tests may include a Breathalyzer or other breath test. You may need to submit to a urine or blood test. These tests assess your blood alcohol level and if you have drugs in your system.

Most states include an implied consent provision as part of your boating privileges. This works the same as the implied consent attached to your driver's license. "Implied consent" means you agree to cooperate with law enforcement when asked to submit to chemical testing. You can refuse these tests. You can still face arrest and charges. You may be subject to additional penalties, especially if you are later convicted.


Generally, for a first offense, BUI is a misdemeanor at a state level. However, you can face a federal misdemeanor charge, depending on who has jurisdiction over the waters where the arrest occurred.

If convicted, you will lose your boating privileges and pay huge fines. You may face jail time or probation and have your watercraft confiscated. You could need to complete a boating safety course before you can reapply for your boating license. Depending on your state, your BUI can impact your driver's license.
