Exhaust sound testing

[Rattlesnake Guy]

Put me down for $100 for the defense fund for the first forum member who is forced to exceed the speed limit and then fails the sound test.

I guess the Target Boat here is the so called GFBLs...the 38' Fountains and Cigarettes...etc. I wonder HOW Many of these boats are actually on the lake. You don't launch a 38' Fountain at a launch ramp on a whim. SO: They are docked somewhere...and probably on a lift. Probably in the Weirs Channel or Paugus Bay area....with maybe a FEW at private residences on the lake.

Maybe some energetic person could jump in their Whaler and take a little putt around Weirs Channel and Paugus Bay. ..to see where the Perpetrators are................JUST to get a n IDEA How Many "Cowboys" there actually are......Nah..... We don't need to know, ..that would just ruin everything. NB

We went to Meredith Bay via Weirs Saturday and I can tell you we saw quite a few Donzis and Bajas and even a couple of Fountains. Not huge ones. No Cigarettes though, but we did see a big Cigarette last weekend. I was happy to see these boats are not ALL gone off the lake.

I have a friend with a 38 ft Baja who was tested, albeit incorrectly, and failed. It seems the officer stuck the probe under the swim platform and announced he failed. I don't really want to get into all he went through, but he had the summons thrown out. He has been asked twice since then to allow a voluntary test, and has declined. At this point, he feels, and I believe rightfully so, he is being targeted.

Bottom line is that when he is asked, he or his wife videos the encounter.

If you own a "be loud" boat, inform yourself of the proper procedures of the testing process, and make sure that these procedures are being adhered to.

BTW, my new boat is a GOBPQ...Goes OK But Pretty Quiet.

Excellent point RG.

On the other hand, can these two or three NHMP sanctioned full-pedal WOT passes for a decibel/sound/safety check be requested by the owners of these "GFBL" boats.?

If I owned a "questionably loud" GFBL, I would want to know BEFORE I got out there that my boat was legal, BEFORE commiting to, say, a week long vacation at the Lake.

Can I change props, check timing, change/sync fuel pressure(s), and request the lightest NHMP officer to ride along.?

Too bad outboards comply. I would call and make an appointment. I need some WOT time to finalize the set-up on a boat I'm dialing-in for NJ.

I don't think it works that way. It is a test, you pass or fail. We lost that boat for most of the summer. Finally passed I think it was early October, the last test of the year.

Hey Tis, glad you got the tongue-in-cheek humor.

That is exactly what happen back in 1998. I was launching my boat at Glendale when an officer came over from headquarters and stuck the probe right right up the exhaust.

Funny, I can only remember a pass and a return pass. Not 4 that Skip mentioned.

Looks like with the SL in place, the officer on board the boat calling the shots, you can't be ticketed for going over the speed limit.

Looks like I found a way to break the SL legally! =)

I'm thinking IF..you are pulled over in your GFBL..for a sound infraction..the MP may be just looking for a WOT RIDE in your HOT BOAT..even if you are not a real canidate for a summons. YUP. Lots of people like a free ride.... NB

PS: SKIP maybe should refrain from commenting here because HE..has been on the ULTIMATE RIDE..On an SSBN. ...or was it an SSN....?? I envy SKIP...and Salute him for his service back in the day.

PPS: SSBN, SSN: Nuclear Submarine. US Navy.

Ayuup....SSBNs for me.

And as a Sonar Supervisor I actually preferred loud boats back then, actually the louder the better...especially when making preparations for coming up to periscope depth!

I worked for a defense contractor that made SATCOM sonobuoys for our submarines. I was always on a surface ship for the tests in San Diego (I know I would have claustrophobia issues!!).

Kudos to those that deploy underwater- it must be a tough life.

Submariners are a special breed. I myself don't believe I could deal with months of being under the water... I think I could take it for a few days, and think the entire things was a great experience, but I would probably go nuts after a week....

Anyways back to the subject at hand.... When you think about the number of boats on the lake, with through hull exhaust and the number of boats that end up being tested...I wonder what the percentage is like. There are many questionable boats that I know off... 3 of which reside on the same road as I do... but I know none of them have ever gotten tested.....

Thanks, Skip! I won't miss an opportunity to thank Skip and his brothers at arms for their service to this country.

Back to sound testing, I've made the point before that the laws are sporadically enforced and troublesome even if enforced. I really think the dealers should be held more accountable for the boats they sell. How often is this law enforced?

270:38 Certification of Marine Engines. – Any marine engine manufactured after December 31, 1976 and offered for sale in this state shall be certified to the director as having been tested and found not to exceed the noise levels prescribed in RSA 270:37, I. An outboard motor shall be certified by the motor manufacturer. Any other marine engine shall be certified by the boat manufacturer if it is offered for sale in combination with a boat or by the engine manufacturer if it is not offered for sale in combination with a boat.

So any boat manufactured before 1976 are not certified at all?? No wonder the old classics are noisy. There is an old late 60's small Cigarette around the Welch Island area that is really noisy!

BH the law I copied says that boat engines made after 1976 have to be certified to meet the sound limits by the builder before they are sold. All boats have to meet the sound laws, but the laws give a small amount of slack to older boats.

270:37 Decibel Limits on Noise. –
I. No person may operate, sell, or offer for sale any marine engine which is capable of being operated in a manner which exceeds the following noise levels measured under any testing procedure established pursuant to rules adopted under RSA 270:39:
(a) For a marine engine manufactured in or before 1990, a noise level of 90 decibels when subjected to stationary testing.
(b) For a marine engine manufactured after December 31, 1990, a noise level of 88 decibels when subjected to stationary testing.
(c) For a marine engine manufactured in or before 1990, a noise level of 84 decibels on the "A'' scale, measured at 50 feet.
(d) For a marine engine manufactured after December 31, 1990, a noise level of 82 decibels on the "A'' scale, measured at 50 feet.

The OLD classic (original) Race BOATS become like ANY Ferrari. They are driven only very infrequently. Ferraris are valued by how many miles they DON'T have on their odometer. Look at any Ferrari FOR SALE..the mileage is usually WAY below 10K MILES...no matter what the year.

Classic Original boats are the same. Some may have TWO seperate engines. One engine may be the original (Very Valuable) antique..the second engine is a modern engine that is swapped in to use the boat a little more often.

The Replicas: Mark Mason (New England Boat & Motor..Laconia) is building Replicas of OLD Race Boats from the Twentys and Thirtys. He offers ready to go hulls...and YOU put in whatever power you want. OR..He will do it for you. He is currently running a white hulled boat (G-36) named IMPSHI.

In the past he restored ...and owned the Original Baby Bootlegger with an original 625 ci Hispano Suiza V8, for over 25 years. Now sold. NB

THE POINT IS: If you have an OLD Classic, (Car, Boat, Motorcycle, Airplane..)to maintain the value of your Classic, you don't drive it much..or the value will go down.

To some of us, the sounds from these boats is beautiful noise.
