Rhode Island BUI Lawyer - Boating Under the Influence

A Rhode Island BUI is boating under the influence, charged under the Alcohol Boating Safety Act, R.I. Gen. Laws § 46-22.2-3. It uses the same 0.08 BAC threshold as a car DUI, but the offense tiers, refusal rules, and suspensions come from the boating chapter and apply to your right to operate a watercraft. Rhode Island has more coastline per square mile than any state in the country and the marine patrol units of DEM and the state police run active enforcement on Narragansett Bay, Block Island Sound, the Sakonnet River, Greenwich Bay, and Salt Pond in Charlestown. A summer afternoon on a boat that ends with a BUI charge can mean a criminal record, a boating suspension, and a $500 boating safety assessment on top of any fine.

Quick answer: Rhode Island General Laws § 46-22.2-3 makes it illegal to operate a watercraft while intoxicated, with a 0.08 BAC threshold for adults and 0.02 for operators under 21. A first offense at 0.08 to under 0.10 is a civil violation: a $100 to $250 fine, 10 to 60 hours of community restitution, a boating safety course, and up to 45 days off the water. At 0.10 or higher, with an unknown BAC, or with any controlled substance in the blood, a first offense is a misdemeanor with up to 1 year in jail, a $100 to $300 fine ($500 mandatory at 0.15 or higher or under the influence of a drug), and a 3 to 6 month watercraft suspension. Every conviction adds a $500 boating safety assessment, and none of it can be suspended by the judge. Implied consent applies on the water under § 46-22.2-5, so refusing a chemical test brings its own fine and a 1 year watercraft suspension. Adult BUI cases are heard in the District Court division covering the waters where the stop happened; operators under 18 go to Family Court. Call 401-573-2265 for a free consultation.

The Rhode Island BUI statute

Rhode Island General Laws § 46-22.2-3, part of the Alcohol Boating Safety Act (Title 46, Chapter 22.2), makes it illegal to operate or otherwise drive a watercraft in Rhode Island waters while intoxicated. Section 46-22.2-2 supplies the definitions and § 46-22.2-5 covers implied consent, testing, and refusal. The structure mirrors the car DUI statute in several ways:

• 0.08 BAC is prima facie evidence of intoxication for operators 21 and older
• 0.02 for operators under 21
• Impairment can be proven without a number, and a legal right to use alcohol or a drug is not a defense
• Any controlled substance in the blood is a separate misdemeanor path under § 46-22.2-3(c)(2)
• Implied consent applies under § 46-22.2-5 - refusing a chemical test triggers its own penalties

The statute reaches any watercraft, including motorboats, sailboats, jet skis, and personal watercraft. It punishes operating while intoxicated, so a boat that is anchored or made fast to shore with nobody at the helm is the first thing my office looks at. For a walkthrough of how one of these cases actually unfolds, see how a BUI case on Narragansett Bay runs.

First offense BUI penalties under § 46-22.2-3(d) depend on the BAC tier:

• 0.08 to under 0.10: a civil violation, not a crime. $100 to $250 fine, 10 to 60 hours of public community restitution, a DEM endorsed boating safety course, and a watercraft suspension of up to 45 days.
• 0.10 to under 0.15, BAC unknown, or any controlled substance in the blood: a misdemeanor. $100 to $300 mandatory fine, 10 to 60 hours of restitution and/or up to 1 year in jail, and a 3 to 6 month watercraft suspension.
• 0.15 or higher, or under the influence of a drug: a misdemeanor. $500 mandatory fine, 20 to 60 hours of restitution and/or up to 1 year in jail, and a 3 to 6 month watercraft suspension.

A second offense within 5 years under § 46-22.2-3(e) is a misdemeanor with a $400 mandatory fine, 10 days to 1 year in jail, and a 1 to 2 year watercraft suspension; at 0.15 or higher or with drugs it is 6 months to 1 year in jail, a fine of at least $1,000, and 2 years off the water after the sentence. A third offense within 5 years under § 46-22.2-3(f) is a felony: 1 to 3 years in jail at the lower tier, 3 to 5 years in prison and a $1,000 to $5,000 fine at the higher tier or when the BUI caused death or serious bodily injury, with the boat itself subject to seizure. A child under 13 aboard adds up to 1 year that cannot be suspended. Every conviction carries a $500 boating safety assessment, and under subsection (l) the judge cannot suspend any fine, suspension, course, restitution, or jail in the section. The BUI lookback is still 5 years; it did not move to 10 with the road DUI statute in 2025.

How Rhode Island marine patrol operates

BUI enforcement on Rhode Island waters comes from several agencies:

Rhode Island Department of Environmental Management (DEM) Division of Law Enforcement. Primary marine patrol. Stations on Narragansett Bay, Block Island, and Salt Pond.

Rhode Island State Police. Patrol higher-volume areas during peak season and event weekends.

Local harbormasters. Newport, Bristol, Warren, Tiverton, Jamestown, Wickford, East Greenwich, and other communities maintain their own harbormaster patrols with enforcement authority.

U.S. Coast Guard. Federal authority over commercial vessels and certain offshore areas. Coast Guard stops sometimes lead to state BUI charges.

Each agency has different procedures and training. A defense often starts with figuring out which agency made the stop and what their specific protocol was.

Common BUI arrest scenarios in Rhode Island

Newport summer. The harbor and surrounding waters during boat show, jazz festival, folk festival, and tennis tournament weekends.

Block Island ferry and harbor. Heavy weekend boat traffic, anchoring violations leading to chemical test situations.

Greenwich Cove and Bay. Boater volume on weekend afternoons with concentrated patrol.

Narragansett Bay raft-ups. Anchored party gatherings where the boat then has to be operated home.

Salt Pond, Charlestown. Shallow water with restricted speed zones and heavy patrol.

Sakonnet River and Tiverton waters. Quieter waters but active DEM patrol.

Wickford Harbor. Concentrated marina traffic.

India Point and Providence River. Lower-volume but active commercial traffic.

Field tests on the water

Standard field sobriety tests do not work well on a boat. The deck moves. Balance is affected by the water. Officers know this and use modified tests:

Finger to nose. Touching the tip of the nose with eyes closed.

Palm pat. Patting one palm with the other while counting.

Hand coordination. Sequential finger touching.

Counting backwards. Verbal cognitive test.

If the officer ran standard car-based field tests on you while on the water, that is a procedural error worth exploring.

Chemical testing rules

Rhode Island uses implied consent for boat operators under § 46-22.2-5, but the mechanics differ from a road refusal. The officer needs probable cause before offering a test, every test must be given within 3 hours of the moment probable cause arose, and the breath machine certification rules in § 31-27-2 apply on the water. A refusal is heard in District Court, not at the Traffic Tribunal, and it cannot be used as evidence of intoxication, only as evidence of refusal. Refusing triggers:

• First refusal: a fine of at least $300, 10 to 60 hours of 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 1 year in jail, a fine of at least $1,000, and a 3 year watercraft suspension
• Plus the $500 boating safety assessment and a $200 Department of Health chemical testing assessment on every refusal

The portable breath test (PBT) on the water is often the first measurement. PBTs are less reliable than the evidentiary machines back at the station. Defense can challenge PBT results on calibration, operator training, and chain of custody.

Defenses in Rhode Island BUI cases

Bad stop. Marine patrol can do safety inspections without reasonable suspicion, but those inspections cannot be used as a pretext for BUI investigation. If the stop was for "documentation check" but the officer immediately started looking for impairment, the stop may be challengeable.

No operation. If the boat was anchored or moored, you were not "operating" it. The state has to prove operation.

Operator identity. If multiple people were on the boat and the operator at the time was not identified clearly, the case can collapse.

Sun, wind, dehydration. Performance on water-based tests is affected by environmental conditions that have nothing to do with alcohol.

Sea legs. Time on the water naturally affects balance and coordination for hours after. This is a real defense in coordination-test cases.

Breath test issues. Same as car DUI defenses - mouth alcohol, calibration, operator training, observation period.

Boater safety license consequences

Rhode Island requires a boating safety certificate for operating most motorized vessels. A BUI conviction can result in revocation of the boating certificate and prohibition on obtaining one for a defined period. Out of state visitors operating under reciprocal recognition face similar consequences in their home state.

The driver license question

The suspensions in Chapter 46-22.2 are suspensions of your right to operate a watercraft. The statute does not direct the DMV to suspend a driver's license for a BUI conviction or a BUI refusal. What a BUI above the civil tier does carry is a criminal conviction that shows on background checks, and a felony at the third offense. If a BUI charge is paired with a road DUI from the same day, for example driving home from the ramp, the road charge follows the normal Rhode Island DUI framework and its license consequences.

Where Rhode Island BUI cases are heard

BUI cases are filed in the District Court covering the waters where the stop happened:

• Newport County waters (most of Narragansett Bay east side, Sakonnet River, Newport Harbor) - 2nd Division
• Washington County waters (Block Island, Salt Pond, South Coast) - 4th Division
• Kent County waters (Greenwich Bay, Apponaug, parts of Bay west side) - 3rd Division
• Providence County waters (Providence River, Pawtuxet) - 6th Division
