Boating under the influence is a crime in Nevada. Specifically, it’s illegal to operate a watercraft
- while under the influence of drugs or alcohol, or
- with a blood alcohol content (BAC) of 0.08% or higher.
Drunk boating or drugged boating is abbreviated
- BUI (boating under the influence),
- OUI (operating under the influence), or
- BWI (boating while intoxicated).
A first-time offense with no serious injuries is a misdemeanor; otherwise, BUI is a felony.
Nevada BUI offense |
Penalties |
NRS 488.410 – no victim was killed or seriously injured | Misdemeanor:
|
NRS 488.427 – BUI following a prior felony BUI conviction | Category B felony:
|
NRS 488.420 – BUI causing death or substantial bodily harm | Category B felony:
|
NRS 488.425 – BUI causing death, and the defendant has 3 prior BUI convictions | Category A felony:
|
Predictably, many of Nevada’s drunk boating cases occur in Lake Mead and Lake Tahoe.
Depending on the case, BUI charges could be reduced or dismissed as part of a plea bargain. There are several possible defenses, including:
- the breath- or blood-testing equipment malfunctioned;
- the police committed misconduct when investigating or arresting the suspect; or
- the boat operator had a medical condition that caused falsely high blood alcohol concentration results

Boating while drunk or high on a drug or other controlled substance is a crime.
1. What is “operating a boat while under the influence” in Nevada?
It is a crime in Nevada “to be in actual physical control of a vessel under power or sail” while either:
- impaired by drugs, alcohol, or other chemicals;
- having a blood alcohol content (BAC) of at least 0.08% even if the person is not impaired from the alcohol;
- having illegal blood levels of the following drugs even if the person is not impaired from the drugs:
Prohibited substance while driving a boat in Nevada |
Prohibited blood levels (nanograms per milliliter) |
Amphetamine |
100 |
Cocaine |
50 |
Cocaine metabolite |

Note that people face BUI charges no matter what kind of vessel they are driving. This includes:
- ships
- yachts
- motorboats
- sailboats
- jet skis1
1.1. Federal law
It is also against federal law under 46 USC § 2302 to drive a boat while under the influence of
- alcohol or
- a dangerous drug.
BUI suspects potentially face prosecution under both state and federal law if the lake or river is federal land. But in practice, it is rare for both state and federal prosecutors to press charges for the same BUI incident.
1.2. Enforcement
In the same way police patrol highways for erratic driving, police also patrol Nevada’s bigger lakes and rivers for erratic boating – especially during Memorial Day and Fourth of July. Nevada also participates in Operation Dry Water, where patrol boats heighten enforcement during one high-traffic weekend a year.
A recent high-profile BUI incident occurred at Lake Mead when a game warden spotted consumer advocate Erin Brockovich struggling to moor her motorboat. She subsequently failed a breathalyzer test and ultimately pleaded no contest in Henderson Justice Court.2
Nevada’s other popular water landmarks include:
- Colorado River
- Truckee River
- White River
- Lake Tahoe (Washoe & Douglas)
- Lake Las Vegas (Clark)
- Lake Mohave (Clark)
- Spooner Lake (Washoe)
- Overland Lake (Elko)
- Wild Horse Reservoir (Elko)
- Wilson Reservoir (Elko)
- Lamoille Lake (Elko)
- Lake Lahontan (Elko & Churchill)
- Topaz Lake (Douglas)
- Angel Lake (Elko)
- Washoe Lake (Washoe)
- Walker Lake (Mineral)
- Pyramid Lake (Washoe)
1.3. Breath and blood tests
Anyone who drives a boat in Nevada gives “implied consent” to take a breath or blood test if a law enforcement officer suspects him or her of operating while impaired.
1.3.1. Preliminary breath test
When an officer first approaches the suspect, the officer may administer a preliminary breath test for alcohol. The officer will arrest suspects who refuse to submit to the preliminary breath test, even if the results would have been negative for alcohol.
The results of the preliminary test may not be used as evidence against the suspect should the case eventually go to trial. This test’s sole purpose is to help the officer to determine whether the suspect may be intoxicated.3
1.3.2. Evidentiary breath or blood tests
Once a BUI suspect gets arrested, the suspect must submit to
- a breath test or
- a blood test.
The results of these tests could come in as evidence if the case were to proceed to trial.
If the officer believes the defendant is only drunk and not high, the suspect may choose a breath test over the blood test. Otherwise, the defendant must take the blood test – this is because breathalyzers do not check for drugs, only alcohol.
If suspects refuse to take any test, then law enforcement may get a court order authorizing them to administer a forced blood draw.4
2. Is boating under the influence the same as a DUI?
Boating under the influence (NRS 488.410) is a separate crime from driving under the influence (NRS 484C.110), but they are very similar. Both laws prohibit being under the influence of alcohol or drugs while driving. The primary difference is that NRS 488.410 refers to driving watercraft while NRS 484C.110 refers to driving on-land automobiles.
3. What are the penalties under NRS 488.410?
The punishment for BUI increases with each successive conviction. And predictably, the sentence is harsher when the incident causes serious injury or death.
3.1. Misdemeanor BUI

A first-time BUI is typically a misdemeanor.
A conviction in Nevada of operating a water vessel under the influence is a misdemeanor as long as no one gets seriously hurt or injured. The penalties carry up to six (6) months in jail and/or up to $1,000 in fines.
In practice, judges also order the defendant to complete
- an online boater safety course as well as
- community service.5
3.2. Felony BUI
Any BUI incident where the defendant has a previous conviction or where a victim was seriously injured or killed is a felony.
Note that judges may not grant probation or a suspended sentence to defendants convicted of felony BUI. Judges also may not dismiss felony BUI charges whenever there is probable cause to support the defendant’s guilt.
Also note that if the defendant’s boat had a passenger under 15 years old, the court will consider that an “aggravating factor.” This means that the judge will order a steeper sentence that he/she would otherwise.
In addition, note that every defendant sentenced for a felony BUI will be required to undergo an evaluation for alcohol and drug abuse.
Finally, note that people sentenced to prison for BUI are usually housed in a minimum-security facility and are segregated from violent offenders.6
3.2.1. BUI following a felony BUI
Getting a BUI after you have been convicted of a felony BUI is a category B felony. The penalty carries:
- two to fifteen (2 – 15) years in prison; and
- fines of $2,000 to $5,0007
3.2.2. BUI causing serious injury or death
A Nevada BUI that causes someone else to die or sustain serious bodily harm is a category B felony. The penalty carries:
- two to twenty (2 – 20) years in prison; and
- fines of $2,000 to $5,0008
3.2.3. Homicide by vessel
Causing death by a BUI when the defendant has three prior BUI convictions is a category A felony. The penalty carries:
- life in prison with the possibility of parole after 10 years; or
- 25 years in prison with the possibility of parole after 10 years9
3.3. Plea bargains

BUI could be reduced to reckless boating.
As with every criminal case, it may be possible to negotiate BUI charges down to a dismissal or a lesser offense.
A common plea bargain is when BUI is reduced to “reckless or negligent boating” under NRS 488.400. This is only a misdemeanor and carries less of a stigma than boating under the influence.
3.4 BUI vs. DUI
Unlike DUIs in Nevada, BUI convictions do not cause the defendant’s driver’s license to get suspended.
Also unlike DUIs in Nevada, BUIs have no “seven-year wipeout” rule: If someone gets a BUI conviction and then seven years pass, any subsequent BUI charges will be prosecuted as a subsequent charge – not as a first-time charge.
And whereas a second-time DUI is a misdemeanor (as long as no one gets seriously hurt), a second-time BUI is always a felony whether or not anyone gets hurt.
4. Can the charges be fought?
As with DUI, there are literally dozens of possible ways to fight Nevada allegations of operating a water vessel while impaired. Five common defenses are:
- The defendant was not the one driving the boat;
- The law enforcement officer did not have probable cause to arrest the defendant;
- The breath- or blood-testing equipment was defective;
- The defendant had a physical or medical condition that causes falsely high BAC results;
- The law enforcement officer committed misconduct (such as not giving the defendant the option to take a breath test when no drug use was suspected)
In every case, the defense attorney would conduct a thorough investigation. This includes everything from
- getting the weather report and interviewing witnesses to
- documenting what the defendant ate prior to the incident and gathering medical records.
Any of these factors could be the difference between a conviction and a dismissal.
If the defense attorney can show the prosecutors that they have too weak a case to prove guilt beyond a reasonable doubt, the state should dismiss the charges.
5. Can immigrant defendants be deported?
Boating under the influence is typically not a deportable offense. However, immigration laws are in a state of flux and are unpredictable.
Any non-U.S. citizen who faces BUI charges should consult an attorney to try to ensure that the case will not threaten his/her legal status.
6. When can the record get sealed?
A misdemeanor BUI conviction may be sealed one (1) year after the case closes. However, felony BUI convictions may never be sealed from the defendant’s record.10
Note that BUI charges that get dismissed can be sealed from the defendant’s record right away.11Learn about how to seal Nevada criminal records.
