A Rhode Island BUI is boating under the influence. It is a real criminal charge with the same 0.08 BAC threshold as a car DUI. Rhode Island has more coastline per square mile than any state in the country and the marine patrol units of the state police and DEM 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 affect your driver's license, your boating record, and your insurance.
Quick answer: Rhode Island General Laws section 46-22-19 makes it illegal to operate a vessel under the influence of alcohol or drugs, with a 0.08 BAC threshold for adults and 0.02 for operators under 21. A first offense BUI carries up to 1 year in jail, fines of $100 to $500, driver's license suspension up to 6 months, a required boater safety course, and boating privilege loss up to 1 year. Implied consent applies on the water, so refusing a chemical test triggers separate penalties. BUI cases are filed in the District Court division covering the waters where the stop happened.

The Rhode Island BUI statute
Rhode Island General Laws section 46-22-19 makes it illegal to operate a vessel while under the influence of alcohol or drugs. The structure mirrors the car DUI statute:
- 0.08 BAC per se threshold for adults
- Lower threshold for drivers under 21 (0.02)
- Combined effect of alcohol and drugs counts
- Operation includes any control over the boat, not just moving
- Implied consent applies - refusing a chemical test triggers separate penalties
"Vessel" covers any watercraft used for transportation, including motorboats, sailboats, jetskis, and personal watercraft. Canoes and kayaks are technically covered but rarely charged.
Penalties for a Rhode Island BUI conviction
First offense BUI penalties:
- Up to 1 year in jail (often probation in first-offense cases)
- Fines $100 to $500
- License suspension up to 6 months (yes, your driver's license can be suspended for a boating violation)
- Boater safety course required
- Boating privilege loss up to 1 year
Second and third offense BUI carries escalated penalties including mandatory jail time, longer suspensions, and substance abuse treatment requirements.
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 just like car drivers. Refusing a breath, blood, or urine test triggers:
- License suspension separate from the BUI charge
- Civil fine under the Traffic Tribunal
- Boating privilege impact
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's license question
Yes, a Rhode Island BUI conviction can suspend your driver's license. The connection between boating and driving offenses comes through the implied consent framework and through specific provisions of section 46-22. A first offense BUI conviction can take your driving license for up to 6 months. This catches a lot of people off guard.
Where Rhode Island BUI cases are heard
BUI cases are filed in the District Court covering the waters where the stop happened:

- Kent County waters (Greenwich Bay, Apponaug, parts of Bay west side) - 3rd Division
- Providence County waters (Providence River, Pawtuxet) - 6th Division
