Sonic AntiFouling? Anyone with experience?

I've been looking at these systems as I keep my 26X in the water year round in S Florida.

From Google searches, they seem to work well at keeping hard marine growth off the hull, but not the grasses. But the green stuff is easy to wipe off.

Anyone with experience with one of these systems?

Should be really easy to mount on a MAC. Two transducers is probably all that is needed. The $1498 system for up to 50' boats is probably way overkill, so I might look into assembling my own system if I can find out more about the transducers they use (frequency and amplitude).

What about the one for stern drives. for $700 +

Sure looks like the way to go. Should pay for itself

Is what this thread reminds me of. On paper it sounds great but in the case of the home "Sonic pest eliminater" there has been lawsuitsfiled by the Gov and many warnings about these devices actually not working.

As for a boat device who knows, time to go to the library and break out consumer guide!!!

I wonder if it really does attract fish if it attracts Great Whites, Tigers, and Bull sharks? Go ahead kids, jump in.

Product Reviews

Antifouling System's Vibrations Can Lure Fish

For Immediate Release
August 2005

For centuries, fishermen have had countless ideas on how to increase their catch. The low-frequency vibrations given off by the electronic resonators of the Barnaclean Sonic Antifouling System from Clean Seas can attract fish in addition to keeping barnacles, oysters and other pests off boats.

After installing the system, many Barnaclean customers report an increase in the number of fish attracted to the boat. "It's definitely been a fish catcher, and now all my competitors are buying the systems," said Dino Varcados, a tournament fisherman, who has had a Barnaclean system installed on his sportfisher for 10 years.

The sonic vibrations invite an assortment of fish to investigate the sounds they hear coming through the hull. Independent studies show that fish are attracted to, create and use sound when involved in the feeding process. These sounds may even attract larger fish to a craft.

The Barnaclean system also allows boaters to get rid of fouling organisms in an environmentally friendly way, without the use of chemicals. In the past, this process has been performed using copper-based ablatives that harm marine life.

Barnaclean electronic resonators emit low-frequency waves that create a moving boundary of water, blanketing the hull and running gear. This moving water keeps fouling organisms from finding a peaceful surface on which to attach itself. Barnaclean also mimics predatory sounds that create an even more inhospitable environment.

The system helps increase speed and fuel efficiency while decreasing maintenance on the vessel. It operates independently 24 hours a day, and the pulsing signal makes power consumption negligible.

Barnaclean is suitable for boats 16' to 75'. All systems come with detailed installation instructions. System 45, for boats 16' to 50', retails for $1,489. For boats 36' to 75', System 85 is priced at $2,988.

We have the "Barnakil" system on our 49 Defever which was installed by a PO a number of years ago. This was the predecessor to the "Barnaclean" system and I believe their has been only minor changes in the design. Also, a name change was in order because they don't kill the barnacles, but only prevent them from attaching. Anyway, the concept is the same.

Before hurricane Ivan, while we were in Fort Walton Beach and I cleaned the bottom of our boat. There were very few barnacles on the hull, however, the props and rudders were well encrusted. Our bottom paint is Trinidad SR which didn't prevent barnacles from attaching to the rudders. We do have units installed on the shaft strut mountings and rudder shafts but these probably don't transfer the vibrations down to the props and rudders as effectively as those mounted in the bilge areas to protect the hull. From our experience, the units appear to work and I have no intention of turning it "off" as a test just to see if I can get barnacles to attach to the bottom.

Hope this helps.

I have had mixed results with my Barnaclean system. Recently replaced
some
resonators with newest models which hopefully are doing a better job on
prop
and rudder. Any comments from other users?

It looks to me like it works well on the hull, but not so well on props and rudders...but that is not important to Macs. I have no idea what to make of the fish attraction stuff.

The concept here sounds like hoohey to me....I would want to understand how sonic waves either disrupt barnacle attachment or discourage them before I forked over my cash...

THose testamonials can be shills of course, and even a well intentioned person can put something on a boat, see a change, and attribute it to a product without due diligence.

Without getting into lots of marine biology about which I know enough to know I dont know squat, a bad storm season can grossly change who/what/how is attaching itself to your boat - so before/after stories have to be done carefully...

So, imho, jury is out, Im skeptical of technology.
