I have set up a Restricted BOD site on the BBS. Lets test it to see if it helps with spam and maybe just makes BOD messaging easier. It still lets us use the email address theboard@foils.org. So once you set up the password on the BBS and set it to forward messages to your email you can see messages either at your email or on the BBS. It also has a voting capability. and will handle any attachments. It also collects all messages on any topic in one place for ease of review. It also has an archive capability to permanently collect old actions.

The first area of the BBS entitled “General Administration” has been resrticted to BOD use. It can not be accessed without a BOD password.

The password for the Board of Directors section is “theboard”

Use the following url on your web browser to go to the password entering page.

http://www.bulletinboards.com/chkpswd.cfm?comcode=foils

Enter the password and check the box that saves it for future use.

This should give you permanent access to this restricted area to conduct all BOD business

If it’s doing away with the XXX.foils.org entirely, there are a lot of references on the website and elsewhere that have to be changed in parallel. This includes all our “profiles” on PayPal.

Ken,

Join the group. I get it re president AND editor. Also get what is
supposed to go to Mark Bebar.

I had talked to Barney about this sometime ago and he felt it was important
for the world to be able to contact the officers of the IHS easily. I
agreed at the time. I must admit that it is less on comcast than it was
when I had erols.

Site Outage

• • The IHS website dropped off the internet for several hours on Thursday 14 August 03 and into 15 August 03 as a result of a massive powerfailure in the Northeastern USA and extending into Canada. Our Canadian Internet Service Provider’s (ISP’s) hardware, the actual residence of our site, was plugged into the failed grid. The IHS site is back up now that power to our ISP has been restored. Hopefully this ISP will develop a remote backup capability that can come on line if the main computers cease to operate. It appears that no email to or from the site was lost (though delivery was delayed). We regret any inconvenience due to the outage.

Maintenance Outage 21 Aug 03

• • The recent problems with the power blackout in eastern USA and Canada was a “wake up call” for our Internet Service Provider (ISP) and many others. As a result, our ISP is making significant infrastructure investments to upgrade their Data Center. This will all be turned on Thursday, August 21, 2003 with the result that the IHS website will be unavailable between 10 pm and 2am (Eastern Daylight Time). This upgrade will yield significantly higher levels of protection from outage due to floods, fire, or electrical failures in the future. It will also provide improved global network speeds for site visitors. Your patience, understanding and support during this scheduled outage are greatly appreciated.

• • hello barney my name is steve and i have a small problem. about fifteen years ago i purchased two hydrofoil kits and had evey intention of building them and because of family duties i was never able to get to them. it is now fifteen years later and i was looking for help in order to build these and i realize through your web site that these are rare models and someone who really knows what they are doing should build them. i do not wish to make any profit on these kits , but i would like to see someone who would do the right thing recieve them , unless i could get help and buid them myself. please advise me . they are by the way the Hegi Police hydrofoil rc ship model and the32nd parallel Schnellbopte model. once again i am not offering this as a joke of any kind i really have these two kits , i just never realized what was going on in the model hydrofoil hobby world. up until 24 hours ago i did not know there was a hydrofoil model society, after reading about the hydrofoil models i realized it would be better to talk to you before i did anything with these kits. the kits are complete with all parts and instructions and i have the origional bills of sale , made out to me. so it is in your hands , i appreciate your time and hope to hear from you soon . p.s. by the way i have not built a model in 20 years and even then i had my problems thanks again Stephen Mc Donald New York U.S.A. if you need photos i will send upon your request

underwater noise level re;dugongs

ViewThread

• • I’m trying to translate a document from Japanese to English where, as a comparison for the underwater noise level produced in a seismic survey (145dB at 100 metres), is given the noise level of a hydrofoil (146db at 100metres).

• • I realise that the dB scale is not the same as for dB in air, but not how or why.

• • What I would like to know is; Is this a realistic figure? What kind of hydrofoil would this be for? Or is the wool being pulled over my eyes? Are the operators of the survey trying to convince us that the noise level is not significantly high?

• • By the way, there are dugongs in the area which are in danger of extinction and may be affected by loud noises.

• • For more info on the problem see

• • Thanks for your time.

Re; underwater noise level re; dugongs

• • Simon,

• • My familiarity with noise measurements is limited, however for airborne noise monitoring there are different scales that are used to account for different applications. Humans for example can tolerate noise pressure levels better at some frequencies than others. If I recall correctly, the dB(A) scale is often used when measuring the impact of noise on humans. This scale weights the noise level differently for each frequency component being measured before adding their effects together.

• • I would say that the same would apply for marine animals, namely that Dugongs could also handle noise levels better at some frequencies than others. Comparing the noise level measured for a hydrofoil (which could be expected to be fairly broad banded) against the output of a seismic system (which may be very narrow banded and in a frequency range harmful to the animal?) could therefore be problematical… regardless of how the dB measurements compare.

• • Good luck with you quest for a sound assessment of the risks in this case. By the way, you seem to have forgotten to include the website link you intended to provide.

Re; underwater noise level re;dugongs

• • I could not help analyzing the noise issue because I doubted seriously the noise measured by the Japanese report can be attributed to the hydrofoil principal alone, and had some potentially useful measurements of my own for comparison.

• • From

http://www.fas.org/man/dod-101/sys/ship/acoustics.htm#conversion

• • , I find the comparison from air to water is +62db for water. The example cited is a supertanker generating 190 dB is roughly equivalent to 127 dB in air. Ambient noise for the open ocean is 74-100 dB. A blue whale also generates 190 dB. They don’t list what Dugongs emit…..

• • While the frequency would probably not necessarily be ‘broadband’, the likely source for a hydrofoil (alone) could be the turbulence in the boundary layer surrounding the foil, various turbulent eddies from vortices, cavitation, ventilated surface bubbles from surface piercing, etc. Weightings may be used (comparing sound levels to the sensitivity of the human ear)and included in the measurement, but any weighting scheme should be reported with the results. Also, the propulsion system (props, water jets, etc.) or support generator sets, etc. would be a major noise contributor.

• • The peak to peak amplitude of a time history of surface pressure can be estimated by 4 times the RMS (or also closely by Std Deviation) of the time history, then converted to Db by 20*Log10(P1/P2), P2 being the reference pressure which is 1MicroPa for water. We recently did some dynamic pressure measurements on the surface of a hydrofoil to measure transition of the boundary layer from laminar to turbulent, for which I have RMS values. A sample I looked at today measured 198 Db average (broadband) at 25 Knots on the foil surface itself. The number was similar for 15 Knots. The above web link relates transmission loss as the sum of spreading and absorption loss. The absorption loss is variable with frequency. Neglecting any absorption loss, 198 dB at the surface translates to 4.9 dB at 100 meters. With absorption included the number is smaller yet.

• • So, if the foil system is sub-cavitating and operating in a cavitation free operating envelope, my opinion is the foils themselves are highly unlikely to cause such a noise level alone.

Engine Torque

• • I’m currently reviewing a design for a small one-person hydrofoil powered by a 15hp-25hp long shaft outboard. The question of engine torque has arisen and the need for an engine mounted torque converter however; in reading a lot of the design material on these pages (excellent guidance by the way) I have yet to come across this issue being discussed. Is torque a major design consideration on small (<9 feet) hydrofoils?
