  • You may not remove or modify a muffler or muffling system if the result is an increase in noise level.
  • No person may operate a vessel that emits noise in excess of 90 db(A) on Maryland waters.
  • Vessels involved in a marine event approved by the U.S. Coast Guard or the Maryland Department of Natural Resources are exempt from the requirements above.
