District of Columbia law prohibits anyone from boating while intoxicated (BWI)—that is, operating a vessel, or manipulating water-skis or similar devices, while under the influence of alcohol; marijuana; or any narcotic drug, barbiturate, or hallucinogen. Alcohol and drugs cause impaired balance, blurred vision, poor coordination, impaired judgment, and slower reaction times. Alcohol is a major contributor to boating accidents and fatalities.

District of Columbia law states that a person is considered to be boating while intoxicated if he or she:

  • Has a blood alcohol concentration of 0.08% or more or a urine alcohol concentration of 0.10% or more (if under the age of 21, any measurable amount of alcohol is considered intoxicated) or …
  • Is under the influence of alcohol, any controlled substance, or any combination of alcohol and a controlled substance such that he or she is impaired.
