Maryland's Boating Under the Influence (BUI) Laws and Penalties

Read about the consequences of boating under the influence (BUI) in Maryland.

By , Attorney · University of San Francisco School of Law

Maryland law prohibits operating or attempting to operate a vessel while under the influence of or impaired by drugs or alcohol. The term "vessel" means "every description of watercraft, including an ice boat but not including a seaplane, that is used or capable of being used as a means of transportation on water or ice."

Maryland has two general classifications of boating under the influence:

  • Boating under the influence (BUI). A person can be convicted of a BUI for operating a vessel while "under the influence" of alcohol. Maryland's BUI statute doesn't define "under the influence." But when a boater had a blood alcohol concentration (BAC) of .08% or greater, the court presumes that the boater was under the influence.
  • Boating while impaired (BWI). A person can be convicted of a BWI for operating a vessel while "so far impaired by any drug, combination of drugs, or combination of one or more drugs and alcohol that the person cannot operate a vessel safely."

In other words, you can get a BUI for boating with an excessive amount of alcohol in your system and a BWI for boating while actually under the influence of drugs or alcohol.

BUI Penalties

The consequences for a first, second, and third or subsequent BUI are:

  • First offense. A first-offense BUI is a misdemeanor and carries up to one year imprisonment and/or a maximum of $1,000 in fines.
  • Second offense. A second-offense BUI is a misdemeanor and carries up to two years imprisonment and/or a maximum of $2,000 in fines.
  • Third or subsequent offense. A third-offense BUI is a misdemeanor and carries up to three years imprisonment and/or a maximum of $3,000 in fines.

A judge can also suspend the boating privileges of any BUI offender who refused a chemical test in violation of Maryland's implied consent laws or had a BAC of .08% or greater for up to one year.

BWI Penalties

The consequences for a first and second or subsequent BWI are:

  • First offense. A first-offense BWI is a misdemeanor and carries up to two months imprisonment and/or a maximum of $500 in fines.
  • Second or subsequent offense. A second-offense BWI is a misdemeanor and carries up to one year imprisonment and/or a maximum of $1,000 in fines.

BUIs and BWIs Involving "Life-Threatening" Injuries

Where a BUI or BWI offender causes an accident where another person suffers "life-threatening" injuries, the following penalties could apply:

  • BUI involving life-threatening injuries. A boater who causes life-threatening injuries to another while under the influence of alcohol or with a BAC of .08% or more is guilty of a misdemeanor and faces up to three years imprisonment and/or a maximum of $5,000 in fines.
  • Alcohol BWI involving life-threatening injuries. A boater who causes life-threatening injuries to another while impaired by alcohol is guilty of a misdemeanor and faces up to two years imprisonment and/or a maximum of $3,000 in fines.
  • Drug BWI involving life-threatening injuries. Generally, a boater who causes life-threatening injuries to another while impaired by drugs is guilty of a misdemeanor and faces up to three years imprisonment and/or a maximum of $5,000 in fines. (For certain drugs, the maximums are two years jail and $3,000 in fines.)

BUIs and BWIs Involving Death

Where a BUI or BWI offender causes an accident involving the death of another, the following penalties could apply:

  • BUI homicide. A boater who causes the death of another while under the influence of alcohol or with a BAC of .08% or more is guilty of a felony and faces up to five years imprisonment and/or a maximum of $5,000 in fines.
  • BWI involving life-threatening injuries. A boater who causes the death of another while impaired by alcohol or drugs is guilty of a felony and faces up to three years imprisonment (up to five years if under the influence of drugs) and/or a maximum of $5,000 in fines.
