Ultrasonic Anti-Fouling

[dennisail]

Wait a minute! I like Meatloaf - especially his concert in Melbourne. I crank it up on my ship's sound system and all the pelagic sealife swims on in to hear.

Exposure to Meatloaf has also been known to kill Siamese cats stone cold on their backs.

Just another minor endorsement of his music.

Maybe a couple of the cuts off Blind Before I Stop.

It doesn't work in warm water, such as Brisbane, Australia even in winter.
The boat next door to me had it, it didn't work.

Sadly the company that made the system we used (a UK firm) went out of business as getting past the mindlock that the only way to deal with fouling is paint and paint alone just was not doable.
...

Is this the company?

If so, looks like they are still in business.

This was first posted on another sailing forum, but may be of interest.
Jaycar an Australian company are offering a DIY alternative.

Ultrasonic Antifouling for Boats - Jaycar Electronics

At $ 249 Aust dollars not as cheap as a Meatloaf CD but cheap enough for a bit of experimentation.

Since the thread revived I popped in to see if someone had actually found one that worked for sure.

Dang!

Nope... The system we used used a dozen transducers which were like little drums. The interesting thing is the electronic control box "pinged" them in sequence so you had the effect of a sound wave going from bow to stern.

A British friend told me he suspected that the transducers were cobbled of British Telecom solenoids from ringers.

I have had my Electromagnetic Pulsing System on a 47' Portofino Sunseeker on trial for over 6 months in Phuket. What was on the hull has fallen off and nothing to date has grown back. A trial will be starting on a commercial ferry cat in Pattaya in the coming weeks. One hull will be cleaned whilst the other is left with what growth is on it.

Our technology has been used on other commercial environments with glaring results. We us 12V D/C square wave transducers. There is 4 bands and these can be pre-programmed to be automatic. We use scientifically verifiable frequencies. PM me with your email if you wish to receive the info on how it works.

I am in the process of having a website constructed to sell online. Our prices will be similar to what is on the market (However ours works) "No snake Oil"

Other than your post, and you are obviously trying to sell the concept,
I have not seen the concept '"work"
The boat next to me had it and it was a complete failure in Brisbane Australia.

Oh, but didn't you know? This guy has figured it out, where everybody else has failed! Don't let the fact that he has zero proof, other than an anecdote about a single boat in Thailand keep you from dropping the big bucks on his system.

We use scientifically verifiable frequencies

Which ones?

Thanks for the non biased, third party review.

There's an article in the February issue of Sail magazine, about Ultrasonic Antifouling Ltd. Product was tested on an aluminum 39' in Portland Harbour, Maine. The author felt the results were encouraging, but he's only had it running for 2 months.

Sail magazine doesn't seem to have the article on their website yet.

Thanks for those that have PM's me and I hope my response was acceptable.
As far as knockers
- go ahead and knock ya heads off and keep ya heads in the sand!!!

I have been involved with this type of technology for over 15 years to date. Mostly with swimming pools and potable water systems. (Other areas as well)
There is many systems on boat hulls with "Varying Results" due to the lack of understanding of how this technology works.
I have researched the ones on the market and their explanations of how it works are ridiculous.
However my friend in Oz has a wealth of knowledge of this from a radar background in Europe and has developed a system with scientifically verifiable frequencies. (Obviously secret)

We all have grown up knowing the fact that a tuning fork can break glass at a certain frequency. Dentists have been using sound for cleaning equipment for over 10 yrs. Mine sweeping timber boats in WW2 had no algae growth on the hulls where the sonar pulse was put through. So it really was only a matter of time before this technology was applicable. "Acceptable is another story."!!!

However it does work otherwise I wouldn't be putting my time and energy into getting anecdotal proof and developing a website to show and sell the technology.

Sorry if I don't have the time or the money to get the propeller heads to prove it works with mathematics!!!
