Take an Official State-Approved Boater Safety Course
Quick Answer
Boating under the influence (BUI) in North Carolina is a Class 2 misdemeanor with up to $1,000 in fines and 60 days in jail. If your BUI causes injury or death, Sheyenne’s Law elevates charges to felonies carrying up to 25 years in prison.

Boating under the influence is one of the most serious boating safety violations in North Carolina, and the law takes it very seriously. Unlike a DUI on land, which affects only you and vehicles around you, impaired boating endangers everyone on the water—passengers, other boaters, swimmers, and even wildlife. North Carolina’s legal framework reflects this danger.
Boating under the influence is defined in NC General Statute 75A-10 as operating any vessel on North Carolina waters while:
The 0.08% threshold is the same as the DUI standard for vehicle driving, but BUI is a separate offense governed by boating-specific statutes, not the vehicle DUI law.
Many people don’t realize that BUI applies to any motorized watercraft, including:
If you’re operating anything with a motor and are impaired, you can be charged with BUI.
This is critical: Boating under the influence is not the same as a DUI, even though they have the same BAC threshold (0.08%).
You can be charged with both a BUI and a DUI if the incident involves both a boat and a vehicle, but they are prosecuted independently.
A first-time or standard BUI conviction carries:
Subsequent convictions (second offense, third offense, etc.) increase penalties. A second BUI within 5 years can result in:
A third or subsequent offense can be treated even more severely.
Sheyenne’s Law, enacted in 2016, is a landmark enhancement to North Carolina’s boating safety law. It’s named after Sheyenne Marshall, a 17-year-old killed on Lake Norman in 2015 by an impaired boater. The law dramatically increases penalties when boating under the influence causes injury or death.
If your impaired boating causes a boating accident that results in serious bodily injury to another person (requiring hospitalization or significant medical treatment):
If your impaired boating causes a death:
If you’ve been convicted of BUI before and your impaired boating causes injury or death, charges escalate further:
For reference:
When you operate a boat on North Carolina waters, you are presumed to have given your implied consent to a chemical test (breath, blood, or urine) for impairment. This is similar to driving on public roads.
Important:
If you refuse to submit to a breath, blood, or urine test:
The NC Wildlife Resources Commission (NCWRC) is the primary law enforcement agency for boating violations on North Carolina waters. NCWRC officers:
During busy recreational seasons (summer holidays, weekends), BUI patrols are often increased on popular lakes like:
As of December 2025, North Carolina enacted additional criminal framework for reckless boating. While separate from BUI, reckless boating charges can be filed alongside impaired boating charges. Reckless boating includes:
This law expanded the tools law enforcement can use to prosecute dangerous boating conduct.
| Aspect | BUI | DUI |
|---|---|---|
| Statute | NC G.S. 75A-10 | NC G.S. 20-138 |
| Venue | Boating safety court | Traffic court |
| BAC Threshold | 0.08% | 0.08% |
| Type of Impairment | Alcohol or drugs | Alcohol or drugs |
| Separate Prosecution | Yes | Yes |
| Record Impact | Boating-related | Driving-related |
| Implied Consent | Boating waters | Roadways |
If stopped on the water, you may be asked to perform field sobriety tests, which are the same as those used in DUI investigations:
You have the right to refuse field sobriety tests, but refusal may give the officer probable cause to arrest you and compel a chemical test (breath, blood, or urine). The decision to refuse is complex and may require legal counsel.
A BUI conviction affects more than just the courtroom:

Sheyenne Marshall was a North Carolina teenager killed on Lake Norman in 2015 when an impaired boater collided with her vessel. Her family’s advocacy led to the enactment of Sheyenne’s Law in 2016, which dramatically increased penalties for impaired boating causing injury or death.
Her story reflects the real, life-altering consequences of boating under the influence. The law exists because of tragedy and serves as a reminder that boating while impaired isn’t just a legal risk—it’s a threat to everyone on the water.
The best approach to BUI is simple: don’t boat while impaired. If you’re on the water:
