Course Outline

Vessel operators may not hear sound signals or voices if the engine is not adequately muffled.

  • All vessel engines must be equipped with an effective muffling device, which may include (but is not limited to) mufflers, exhaust restrictors, and water-injected exhaust headers.
  • The use of cutouts or non-muffled headers is prohibited, except for motorboats that are competing in an approved regatta or boat race.
