Boating Under the Influence in Rhode Island - How a BUI Case on Narragansett Bay Actually Runs

Boating under the influence in Rhode Island is charged under R.I. Gen. Laws § 46-22.2-3, the Alcohol Boating Safety Act, and it runs on a different track than a road DUI. The per se limit is the same .08, but the offense tiers, the refusal rules, and the court deadlines all come from the boating chapter. A first offense can be anything from a civil violation with a $100 to $250 fine up to a misdemeanor with a year of possible jail.

If DEM Environmental Police, the Coast Guard, or a harbormaster stopped you on Narragansett Bay and you tested at .08 or higher, you are looking at a charge in District Court, a suspension of your right to operate a watercraft, and a $500 boating safety assessment on top of any fine. I have handled these cases for more than 20 years. Here is how one actually unfolds.

The Statute Behind a Rhode Island BUI Charge

The boating statute is Title 46, Chapter 22.2. Section 46-22.2-3 sets the offense and penalties, § 46-22.2-2 supplies the definitions, and § 46-22.2-5 covers implied consent, testing, and refusal. "Operator" is the person steering while the boat is underway, and "underway" means not at anchor and not made fast to shore, so a boat rafted up in Potter Cove with the engine off is not underway.

BAC Thresholds and Offense Tiers Under § 46-22.2-3

Under § 46-22.2-2(5), a blood alcohol level of .08 or more is prima facie evidence of intoxication for anyone 21 or older, and .02 for anyone under 21. A reading of .05 but under .08 is "relevant evidence," enough to arrest on but not proof by itself. The structure mirrors the BAC limits on the road.

First offense

• .08 but under .10: a civil violation, not a crime. $100 to $250 fine, 10 to 60 hours of public community restitution, and a watercraft suspension of up to 45 days.
• .10 but under .15, BAC unknown, or any controlled substance in the blood: a misdemeanor. $100 to $300 fine, 10 to 60 hours of restitution and/or up to one year in jail, and a 3 to 6 month watercraft suspension.
• .15 or higher, or under the influence of a drug: a misdemeanor. Mandatory $500 fine, 20 to 60 hours of restitution and/or up to one year in jail, and a 3 to 6 month watercraft suspension.

Second offense within 5 years

• .08 but under .15, or BAC unknown: a misdemeanor. $400 fine, 10 days to one year in jail, and a 1 to 2 year watercraft suspension.
• .15 or higher, or drugs: a misdemeanor. Mandatory 6 months to one year in jail, a fine of at least $1,000, and a 2-year watercraft suspension after the sentence ends.

Third or subsequent offense within 5 years

• .08 but under .15, or BAC unknown: a felony. $400 fine, 1 to 3 years in jail, and a 2 to 3 year watercraft suspension.
• .15 or higher, drugs, or a BUI causing death or serious bodily injury: a felony. 3 to 5 years in prison, a $1,000 to $5,000 fine, a 3-year watercraft suspension after the sentence ends, and possible seizure of the boat.

Across every tier, subsection (h) adds a $500 boating safety assessment, subsection (g) allows up to one year with no suspended sentence when a child under 13 was aboard, and subsection (l) says none of the fines, suspensions, or jail can be suspended at all. Note also that the road DUI lookback moved from 5 to 10 years on July 1, 2025, while the BUI statute still reads "within a five (5) year period."

Who Enforces BUI on Narragansett Bay

Section 46-22.2-2(4) defines "law enforcement officer" to include environmental police officers of the Department of Environmental Management. DEM Environmental Police write most of the BUI cases that reach my office. The U.S. Coast Guard boards recreational boats too, and an impaired operator found during a Coast Guard boarding is usually handed to DEM or a local department for the state charge. Harbormasters and town marine units stop boats too.

Operation Dry Water is the national enforcement push around the July 4th weekend, when DEM, the Coast Guard, and local units flood the water with patrols looking for impaired operators.

How a Stop on the Water Differs From a Road Stop

On the road, an officer needs reasonable suspicion to pull you over, and Rhode Island bars DUI checkpoints under Pimental v. Department of Transportation, 561 A.2d 1348 (R.I. 1989). On the water, DEM and the Coast Guard can stop and board a vessel for a safety inspection with no suspicion of wrongdoing at all.

A suspicionless safety inspection is lawful, but demanding a breath sample requires probable cause under § 46-22.2-5(b). What the officer saw and smelled, and when, decides whether the impairment investigation was justified. The other difference is operation: the boat must be underway and the person charged must be the one steering.

Sobriety Tests and Breath Testing on the Water

The standard field sobriety tests were validated on dry, level pavement. The walk and turn and the one leg stand cannot be done on a rocking deck, so DEM officers use seated tests: horizontal gaze nystagmus, finger to nose, a hand pat, and a palm-clapping exercise. Sun, wind, and a day of engine vibration mimic impairment, and I hold officers to their training on that.

Under § 46-22.2-5(a), anyone who operates a watercraft in Rhode Island waters impliedly consents to chemical testing. The officer must have probable cause before offering a test and must complete every test within 3 hours of the moment probable cause arose. Subsection (f) makes the breath machine rules in § 31-27-2 apply to boating cases, so the same calibration and certification requirements I attack in a road case apply here.

Refusal Consequences Under the BUI Statute

A road refusal under § 31-27-2.1 is a civil matter at the Traffic Tribunal in Cranston. A BUI refusal under § 46-22.2-5(i) is heard in District Court:

• First refusal: fine of at least $300, 10 to 60 hours of public community restitution, and a 1-year watercraft suspension.
• Second refusal within 5 years: a misdemeanor, up to 6 months in jail, a fine of at least $600, and a 2-year watercraft suspension.
• Third refusal within 5 years: a misdemeanor, up to one year in jail, a fine of at least $1,000, and a 3-year watercraft suspension.

Every refusal also carries the $500 boating safety assessment plus a $200 Department of Health assessment. Under subsection (e), the refusal cannot be used as evidence of intoxication, but it can be used as evidence of refusal. Before it is imposed, the state must show the officer had reasonable grounds, that you were told your rights, and that you were told the penalties for refusing. If the rights form was read on a pitching deck over an outboard, that showing is not automatic.

Which Court Hears It and What Happens to Your License

Section 46-22.2-3(k) gives jurisdiction to District Court for anyone 18 or older and Family Court for anyone under 18. Providence County stops go to the Sixth Division at the Garrahy Judicial Complex. Kent County goes to the Third Division in Warwick, Newport County to the Second Division in Newport, and Washington County to the Fourth Division in Wakefield. A felony goes to Superior Court. The statute also requires District Court trials to be scheduled within 30 days of arraignment.

The suspensions in Chapter 46-22.2 are suspensions of the "right to operate a watercraft." The statute does not direct the DMV to suspend a driver's license. A BUI above the civil tier is still a criminal conviction that will show on background checks.

How I Handle These Cases

First, I get the DEM or Coast Guard boarding report, any patrol boat video, and the breath machine logs. I want to know whether the stop began as a safety inspection and when it turned into an impairment investigation. Second, I look at operation: who was at the helm and was the vessel underway. Third, I check the chemical test against the 3-hour window and the § 31-27-2 certification rules. Fourth, I review the rights advisement on any refusal. Because subsection (l) strips the judge of any power to suspend a BUI sentence, the pressure points are in the evidence, not at sentencing.

My Rhode Island BUI defense page covers the broader approach, and my breathalyzer refusal page explains the road version of that fight. As an RI DUI lawyer, I treat a boating charge with the same seriousness as any other impaired operation case.

Frequently Asked Questions

What is the legal BAC limit for boating in Rhode Island?

Under § 46-22.2-2, a blood alcohol level of .08 or higher is prima facie evidence of intoxication for operators 21 and older, and .02 for operators under 21.

Is a first offense BUI in Rhode Island a crime?

A first offense at .08 but under .10 is a civil violation under § 46-22.2-3(d)(1), not a crime. At .10 or higher, with an unknown BAC, or involving drugs, it is a misdemeanor with up to one year of possible jail.

Can DEM board my boat without a reason?

Yes. DEM Environmental Police and the Coast Guard can board a vessel for a safety inspection without reasonable suspicion. The officer still needs probable cause before offering a chemical test under § 46-22.2-5(b).

What happens if I refuse a breath test on a boat in Rhode Island?

A first refusal under § 46-22.2-5(i) carries a fine of at least $300, 10 to 60 hours of community restitution, and a 1-year watercraft suspension. It is heard in District Court, not the Traffic Tribunal.

Will a Rhode Island BUI suspend my driver license?

The suspensions in Chapter 46-22.2 apply to the right to operate a watercraft, and the statute does not direct the DMV to suspend a driver's license.

Which court handles a BUI from Narragansett Bay?

Section 46-22.2-3(k) sends adult cases to District Court and juvenile cases to Family Court. The division depends on the county where you were brought ashore. Felony BUI charges go to Superior Court.
