Summer on the Eastern Shore means crowded waterways and active Maryland Natural Resources Police patrols on the Wicomico River, the coastal bays near Ocean City, and the tidal waters stretching through Somerset and Worcester counties. Most boaters who get stopped are genuinely surprised to learn that boating under the influence in Maryland carries nearly the same legal weight as a DUI: criminal penalties, a cross-conviction rule that can follow you onto dry land, and recent statutory changes that most people have never heard of.
At MacDonald Law Office, LLC, Andrew and Cynthia MacDonald both spent time on the prosecution side of the courtroom before shifting to defense work. That background matters in BUI cases because understanding how NRP officers are trained to document a stop and build a case shapes every decision we make in defending one.
How Maryland Defines Boating Under the Influence
Maryland Natural Resources Article Section 8-738 governs boating under the influence on Maryland waters and mirrors the state’s DUI law almost exactly. A blood alcohol concentration (BAC) of 0.08 or higher triggers a per se BUI charge. The number alone is enough to support the offense without additional evidence of impairment. A BAC between 0.07 and 0.079 supports a lesser charge of operating a vessel while impaired by alcohol, the boating equivalent of a DWI.
The law applies to motorized vessels and vessels under sail on Maryland’s tidal and non-tidal waterways. That covers significant ground locally: the Wicomico River, Chincoteague Bay, the Isle of Wight Bay near Ocean City, and the coastal bays throughout Worcester County are all within scope. Refusing a breath or blood test after a lawful stop triggers an administrative per se suspension of boating privileges, a separate consequence that runs parallel to any criminal case.
What a BUI Conviction Actually Costs You
The criminal penalties under Section 8-738 are serious. A first-offense BUI conviction carries up to one year in jail and a $1,000 fine. A first-offense impaired-by-alcohol conviction carries up to 60 days and a $500 fine. Those numbers climb quickly with prior offenses, and two recent legal changes have raised the stakes significantly for anyone with prior alcohol-related charges, on or off the water.
The October 2023 Cross-Conviction Rule
An amendment that took effect in October 2023 changed how Maryland counts prior offenses for sentencing purposes. A prior BUI conviction can now be used to enhance sentencing on a subsequent DUI charge, and a prior DUI conviction can enhance a subsequent BUI. Before this change, the two offense types were treated as separate categories and didn’t count against each other. Now they do. If you were charged with DUI at any point and are later charged with BUI, or vice versa, the earlier offense can increase the penalties you face.
Nick’s Law: 2024 Boating Privilege Changes
Nick’s Law, passed in 2024 and named after Nick Barton, a 21-year-old killed in a 2022 boating accident on the West River, extended boating privilege suspension ranges for offenders. Effective July 1, 2024, courts can ban a vessel operator convicted of an alcohol-related BUI from Maryland waters for up to two years (up from a prior maximum of one year) and up to five years when the offense involved a death. These suspensions are administered separately from any criminal sentence and carry their own procedural deadlines and hearing requirements.
How NRP Officers Build a BUI Case on the Eastern Shore
The Maryland Natural Resources Police Eastern Region Area 1 office is located on Mount Olive Road in Salisbury and covers patrol on Somerset, Wicomico, and Worcester county waters. During summer months, NRP runs concentrated enforcement operations targeting alcohol use on the water, and the area around Ocean City sees some of the heaviest activity.
One of the most defensible aspects of any BUI case is the field sobriety testing that typically happens on or near the vessel. These standardized physical coordination tasks were developed and validated on dry land under stable conditions. Vessel motion, wind, sun glare, and cumulative fatigue from a full day on the water can all affect balance and coordination in ways that have nothing to do with alcohol. Challenging the validity of those results is often a central part of the defense.
NRP officers complete the Maritime Law Enforcement Officer curriculum, which includes specific protocols for documenting vessel stops, administering sobriety assessments, and building the probable cause record that supports an arrest. Knowing what that training requires officers to do, and where documentation can fall short, is exactly where our prosecutorial background translates into a defense advantage for our clients.
BUI & DUI: How They Interact on Your Record
A BUI conviction is a criminal conviction. It appears on your record and, under the October 2023 cross-conviction rule, can be treated as a prior offense if you’re ever charged with DUI. A future traffic stop, even years later, could carry stiffer penalties because of something that happened on the water.
A BUI conviction doesn’t automatically suspend your driver’s license, which leads some people to underestimate it. But the cross-conviction enhancement closes much of that gap. Your driving record and your boating record aren’t treated as independent for sentencing purposes anymore.
There are also two separate administrative processes to navigate. The Maryland Motor Vehicle Administration handles driver’s license proceedings under standard DUI law. Boating privilege suspensions go through a different process with their own deadlines. Missing a hearing or response window in either proceeding can produce consequences that are harder to undo than the criminal case itself.
Where Eastern Shore BUI Cases Are Heard
Where your case is processed depends on where the arrest occurred. BUI cases from Wicomico County are heard in the Wicomico County District Court in Salisbury, directly across from our office. Worcester County arrests, including those made in Ocean City waters, are processed through the Worcester County District Court in Snow Hill.
The recent changes to Maryland’s BUI law, particularly the cross-conviction rule and the expanded boating privilege suspension ranges, don’t get much attention in general legal overviews, but they have real consequences for anyone charged on the Lower Eastern Shore.
