View Full Version : AZ and NV noise decibel law...

For those interested, AZ and NV decibel law follows. My earlier post operated on a flawed assumption regarding the lack of current law. Better to be armed with information, but the new laws do not portend well for performance/hot boats ...

Here is the current AZ law on noise. It's pretty vague and open to legal interpretation on both enforcement and violation sides given the lack of decibel specifications (i.e., excessive and unusual may be legally interpreted as something outside of manufacturer installation and typically for race oriented use):

5-336. Muffling devices
A. Every motor driven watercraft shall at all times be equipped with effective
equipment, in good working order and in constant operation, to prevent
excessive or unusual noise except as provided in subsection C.
B. It is not the intent of this section to prohibit the use of any type of
exhaust system or exhaust device, including those systems and devices which do
not discharge water with the exhaust gases, if such system or device complies
with subsection A of this section.
C. All watercraft actually competing in a regatta, boat race or official trials
for speed records, and within the time limits authorized by the sanctioning
body of such event are exempt from this section. Permits designating place and
time limits are required and shall be issued by the department prior to the
testing of watercraft on the water when sufficient evidence is provided by the
applicant that such watercraft is actually entered in an event sanctioned by a
national or regional organization having jurisdiction over the event.


Here is a link to NV law: http://www.boatnevada.org/laws/noise.pdf.

NV has specific dB levels and distances as follows:
75 decibel maximum as registered from shore.
86 decibel maximum as registered 50 ft. from the craft making the noise.
90 decibel maximum proximal to transom if the boat was built prior to 1/1/93.
88 decibel maximum proximal to transom if the boat was built on or after 1/1/93.

Most boaters on this site will not comply with the new NV statutes, for 86-88 decibels is when
you have to shout to communicate with someone in the same room, or in a boating case,
when you have to shout to get someone in the boat next to you to hear what you are saying. The test for me is when I have to turn off my engine to communicate with the occifer (no
not a misspelling) that is idling beside me he will be pulling out his noise tester.

I, for one, am not looking forward to installing electrical baffles at a grand or so. NV fines
are similar to safety violations (e.g., around $150.00 per and the potential of being towed to
the doc with a citation for non-use of the craft until re-inspected).

Perhaps the cops can purchase ear plugs, or perhaps I'll do more of my boating in AZ? http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/smile.gif.

Hope the info. is helpful, though clearly disappointing.

Thanks for taking the time to post all that info. I was seriously considering going to through transom exhaust this winter. I think I'm going to wait and see how this plays out over the next two summers. Doesn't look good...I can see it now: 2006 LVHB post: "Who's going to this weekends SeaRay Regatta?" http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/wow.gif

Mead and Mojave are patroled by the National Park Service. Not Nevada or Arizona. NPS regs are different.

That's only part of it for Arizona. Â*Here is the rest.

Arizona Revised Statutes
Title 12 - Natural Resources
Chapter 4 - Game and Fish Commission

R12-4-516 Watercraft Sound Level Restriction
A. Â*It shall be unlawful for any person to operate a watercraft upon the waters of this state under any condition or in any manner that the watercraft emits a sound level in excess of 86 decibels on the "A" weighted scale when measured from a distance of 50 feet or more from the watercraft
B. Â*This Section shall not apply to watercraft operated under permits issued in accordance to ARS 5-336©

The more info. that comes in on the threads here, the worse the legal situation appears ... I think I'll just run as is for awhile and then contest the tickets in court as I receive them.

Anyone know where you can purchase a quality decibel meter that has the appropriate scales (e.g., "A")? I think I'll test my own boat and have the data handy if I pass in case I get stopped.

I think Radio Shack sells something like that. (Decibel meter)


I spend most of my time in the Virgin Basin past the narrows. If I do launch at Callville I leave right away. Echo is nicer and less crowded and the Water Cops are seldom ever seen.


I like to think that the lake would not be the lake unless you could hear a Hot boat hauling ass across the water. As a kid I bet that sound is what made you want the boat you have now. http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/cool.gif

Hey RedHorse...I think TMF said "quality"! Â*http://www.lasvegashotboats.com/iB_html/non-cgi/emoticons/biggrin.gif Â*RadioSh$t won't be that!

I'm off to RadioShack in a minute ... good decibel meter costs under $50.00, well under the price of one ticket. Also spoke with an attorney friend of mine in CA and his read was that folks willing to pursue ticketing in court had the ticket dismissed most times due to lack of legal point ...

AGREED!!!!!!! re: Red Horse's comment that the hot boats of the 60s and 70s in the Fla. waters are what stimulates me to have what I run today ... and the lake IS the lake because of those boats running by...

I can see the point of minimizing exhaust noise at Lake Tahoe or any other lake with people living on the water (although I don't agree with it ) but what purpose does keeping exhaust noise down serve at a lake like Mead? Are we afraid of scaring the big horn sheep? It doesn't make sense.
