MUFFLERS

The manufacturers of recreational boats are required to construct boats using efficient muffling devices. State laws prevent the use of boats without efficient muffling devices, and many states require the devices to prevent noise levels at established decibel ratings. Boat operators should always maintain muffling systems that prevent unacceptable noise levels. All vessels equipped with an engine must be effectively muffled by equipment constructed and used to muffle the noise of the exhaust in a reasonable manner.

Tennessee Muffler Law

• No person shall operate any vessel in or upon the waters of Tennessee in such a manner so that the total noise produced by the watercraft exceeds 86 dBA at a distance of 50 feet or more, whether or not said vessel is in motion.
• Any duly commissioned officer of the Wildlife Resources Agency with a reason to suspect that a vessel is exceeding the noise limitation may require the vessel operator to transverse a noise emission test course as set forth herein.
