Course Outline

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

  • In New York, it is illegal to install muffler “cut-outs.”
  • Vessel engine noise may not exceed:
    • 90 decibels during a stationary test conducted alongside a dock or…
    • 75 decibels when tested while passing offshore.
  • It is also illegal to remove, alter, or modify the muffler system in such a way that will prevent a vessel from meeting these standards.
