Gatorstick,
What do folks need to do, if they desire to actively participate in this demonstration? Register with someone? Who will that be?

What is the objective of the demonstration?

Is it to find out which airboat generates the most thrust, at the lowest db?

Just to find out which boat is quietest in it's maximum operating range?

Will there be a performance measurment factored into the evaluation?

Your looking for participants with innovative designs, that reduce sound signatures, with-out compromising performance? I'm sure you don't want 50 boats showing up, with newly installed mufflers, and no real departure from conventional airboat design.

Please advise, because I know some folks who want to bring a new set-up. This boat may provide some of the best thrust per db numbers avaiable. They want to find out, and don't we all?

Either way you are going to evaluate the boats under test, I know you would want to include one of these set-ups. That is if you really want to evaluate every thing that's available for airboat sound reduction.
 
I heard that they would have a db meter and check hoe you boat dose on a plane and also would have to run dry ground and see how loud the boat is and to see what combo is the quitest mainly to see where you own boat is. and just to show we are trying to make a differnce
 
That's right, CC ...
I don't want to say too much about the event just yet because I'm just a worker bee for it. Mr. Jim Brown, Pres. of the Lake County Airboat Club is the event chairman, and there are a lot of details yet to be worked out, but it's going to be on-the-water testing through a specified, marked area, and done with a sound meter.

There will be on-site registration the morning of the event, and it's open to anyone. Obviously the guys who have worked hard to build a high tech quiet boat will be given preference first, and then if time permits we hope to be able to give a lot of other folks some real numbers with their boats too.

More info as we have it.

What is the date and what time do you need to be registered by. I'm bringing my boat and I have put it on stealth mode. I'm sure the counter rotators will be the quietest.
 
Thunder, the CR's haven't been the quietest so far ..... two props to deal with. Lookin forward to your Stealth Thunderboat.

Right now it looks like registration will be from 10am until noon. We'll let y'all know if that changes. My wife will have her laptop and a portable printer with her, with the registration form already loaded. You'll just give her your information and she'll print out your form on the spot. Then, after you run, we'll write in the numbers the boat blew.
So far, that's the plan. We want to try to make it as fair as we can for everybody.

Open to suggestions, though.

Cool I just want to have fun, I have never in my entire life tried making an engine or airboat quite then again I have never built a motor aimed at fuel economy and look how far that has gone lately. I hope to be mid pack while only spending $400 on my complete exhaust!
 
May 20th, at Loughman. We may move up the river a little to give the folks at the Lodge a little space, but it'll be announced for sure .....

Umm ... red head?

Quiet Airboat DemonstrationLoughman's Lodge May 20th

FAA Event Committee Chair: Jim Brown- lake County Airboat Club
Committee members: Ken Johnson-CCAA Capt. Bob Hoover-CCAA
Capt Dave Markett-KRVSA

This will be a real world demonstration of how we operate airboats with no trailer testing. The purpose will be for participants to demonstrate ideas, concepts & theories on how to drop the sound down during normal airboat operation, with classes for engine types. For spectators, we wish for them to gain ideas for sound reduction in real world use.

Tentatively, there will be a water course with the possibility of some dry ground running. So far the concept (subject to change of the above committee) will be to measure sound during a short dry ground run, then run a water course going into a measured trap. In the trap will be measurements taken:

1) On a plane
2) At an idle
3) Enter the trap at idle then jump onto a plane before leaving the trap
4) Dry ground run (may be optional)

Hopefully, this will be a general representation of our normal operation and if the boat can't run the course, it may prove it's not an operational airboat.

We will have Dr. Glegg, an Acoustical Engineer from Florida Atlantic University bring their equipment to measure the sound. These are the same folks who conducted the research for FWC & have no dog (bias) in this issue.

Hopefully, this event will get our redneck innovative juices flowing while reducing airboat operational sound which in turn will reduce the complaints many outdoor recreational users have concerning our activities.

Food for thought: The more active position we take upon ourselves to reduce sound (and do it) the brighter our future will be and the less likely SOMEONE ELSE will be dictating sound levels to us.

If you have comments, send them to Big Feather as he's on the committee. We hope to have the final details & info out to the public by April 1.

We hope to have a media & guest friendly event, so come on out! If you want to volunteer to help, contact Big Feather.

Thunder I'm jokin about the redhead, I was makin a silly reply to Cntry141 about anybody got a date.

HOWEVER, In trying to figure out WHO FH is, I assume its Flatz Honkey, I find he is registered twice. #39 and again as #516. So the member count is one less. Unless we have two Flatz Honkies? ( I don't know eiether of them)

I would come but by May 20 I will have been home on vacation and be back here in Doha til the end of the year.

I'd love to be at this event though !

Can you elaborate a little on the above statement, as in, what it means if you have a non-operational airboat?

Our old boat won't run dry whether it part of the course or not. Will that disqualify it - as "not operational"? I'd think that if it makes SOUND, it's an Operational Sound Generating Device - with potiential to generate a complaint depending on the time/place/driving habit which we operate it with.

Hatbill park is overflow parking? If not, it's a nice place. Thinking of launching our boat from there just to avoid some of the mayhem.

I hope there is some sort of EFFECTIVE sound system to announce when a measurement is being taken so we in the audience know when to hush up. Or I suppose you could take the measurements on the other side of the lagoon. Also, it'd be nice to hear a boat go by, and instantly have some numbers announced so we can train our ears to the association between a sound and a number. Besides, it makes the betting easier. :lol:

If you need a kicker boat, let me know. I got the 14' aluminum with a 10hp putter that could make a good mic stand at anchor.

And for kicks, do you think it'd be possibe to measure some Jet Ski's just for comparison? In other words, is it possible for ANYONE to enter ANY type of craft? Of does it have to be airboats ONLY?

Mood,
The reason for running dry as part to qualify as an airboat is that we didn't need the argument if someone came with some hokey built contraption with a B&S 3.5 horse in a 7 ft. jon boat and called it an airboat. If it looks like an airboat, PERFORMS like an airboat,Runs ground like an airboat, it must be an airboat.
There are a few details that nobody has asked yet (I'm surprised), like are spray systems allowed? YES, using biodegradable soapy-water only. NO petroleum products. Can you have your buddy's help wiggle you across the dry ? YES, just dont run over them or they start screaming and that ruins things :lol: . Remember, performs like in real world. And yes, buddy's are real world :wink: .

Careful Swampjet, you might make some of the mini members on here upset.... 8)

I guess I don't have an airboat then. Is this a clue as to what is coming in the law's definition of an airboat? If so, I have no worries, not havin an airboat. The laws will not apply to me?

Bob - before you "cringe" - that's a rhetorical question. Of course I have an airboat. It's means of propulsion is air.

I see the point about running dry. Real life. hmmm... for me, I'll take that to mean "getting stuck" LOL :lol: I can do that with NO PROBLEM!!!! :lol: In the real life of our boat, we don't run dry and are getting better at not getting stuck! The dry run is a replacement of the trailer test - it appears.

But so what if someone came with a B&S jon-boat? It's capable of generating a complaint too, is it not? And it'd be a complaint that we ALL would be blamed for! So why not educate/encourage those kind to quiet down too? (although, a boat that small would probably pass anyway)

The 90 db at 50' reg was adopted in Marion County because a person claiming to be an "airboater" brought a modified to oblivion boat to the county commission meeting, stood on the throttle and blew 86 dB wide open.

The point (or deception) to the Marion County Commission: Airboats can be very quiet wide flat open (tested on a trailer) if the dirty, renegades would tone down their boats.

Fact: At the FWC testing January 2005, I witnessed this same boat in action. 12' direct drive 350 Chevy with 2 of 4 barrels blocked. After 20 minutes in the water, the boat would not plane because of the "modifications." In my opinion, this is not a real world, operational airboat & should not have been qualified for the FWC testing nor used as an example for Marion County.
However, it was used in documented testing and is now documented, academic, researched "fact," for the world to see.

While you can write all the rules & definitions you want, someone is always looking for a loophole. I prefer the adage "Seeing & doing is believing."I have been adamant in making all activities related to this issue be conducted in a real world setting and in real world conditions, not on a theoretical or staged venue.

Mood my next boat will be jet powered If I can just figure out how to keep from setting the marsh on fire.
