ultra sonic hull cleaner

Ultra-SoniTec – Ultrasonic Antifouling | Providing the world’s best ultrasonic antifouling system for all boats.

Is this just snake oil or has anyone on the list actually used this product?
It sounds interesting but it is by no means cheap.

if used how hard to install. It looks like it is installed inside the boat?

Ultra sonic cleaning of industrial equipment really works and has been around for a long time. It has many marine applications, in my case engine after coolers. In the US cleaning hydro electric dam generators's bits and pieces is practiced. In fresh water the zebra mussel buildup has been an application.

Recreational boat hulls - I'll ask my diver what he has heard.

Ultra sonic cleaning is effective. My question though, is does this device actually work.

FWIW... This is what one Nordhavn owner from Sarasota, FL had to say about the product:

We departed Sarasota on April 15th for a three month cruise to the Bahamas. The day before we left we had the bottom cleaned, and the diver reported that the bottom paint was in fair condition (painted in March 2012 with Sea Hawk Biocop TF Black so now over two years old). By the time we reached Bimini the grass at the water line on the port side was about 4 long, the bottom and stabilizers were white with growth with many barnacles.

As we were waiting for weather for a few days, I took the opportunity to install the CleanAHull Ultrasonic Antifouling System I had acquired from Ultra-Sonitec.com before leaving Miami. The installation took about 12 hours with a bit of help from my first mate in pulling the wire runs. I then cleaned the bottom, which took me about 6 hours!

It is now five weeks since the installation and I am extremely pleased with the results! No grass, no barnacles, and only a thin coating of slime, which easily wipes off with a scotch pad! Even in areas where the paint is worn off, and the underwater light lenses, are free of growth! These are excellent results, especially considering that we have been at anchor for most of the past five weeks rather than underway almost every day as in the first part of our cruise.

I have no financial interest in Ultra-Sonitec, just a satisfied customer.

Don Payzant, Owner, June 2014

I saw that on their, ultra sonic website.
Not sure one could trust from there. Just seeing if anyone from our forum has used this.

If in doubt of the validity of his testimonial contact him directly, I'm sure he wouldn't be hard to locate.

It would take me 2-3 years in eliminated diver/haul-out cost to pay it off. But, I would still haul-out for the inspection value of putting her on the hard, plus I always seem to have something to fix or improve that gets deferred to the next bottom job.

So I'd still be doing the hauls, might be able to knock off the diver a couple of times a year - all predicated on the device's performance as advertised. Not cost effective in my situation.

But, very interesting concept.

Correction - 2 or 3 haul-out cycles - not years.

My understanding from boat show discussions and a local installer of the system--it doesn't "clean the hull", it keeps it clean.
The ultrasonic waves are pulsed at particular time intervals and durations and this kills the organisms on the hull while still micro (or at least very small).

You have to wonder why ultrasonic systems aren't in widespread use, if they actually perform as advertised. I have been in the hull cleaning biz for 22 years/30,000 service events and have never come across one.

You can't trust "testimonials" any more than you can trust advice on this forum. The only way you're going to find out if this system works for you is to install it on your own boat.


Wait five years and they will either be on most people's boats or the company will have gone out of business. At that point, you can make a decision.

I used to be an installer for another brand of ultra sonic hull "cleaner".

And they did work but as noted they don't clean the hull. They just help kerp a clean hull clean and barnacle free (or almost barnacle free) a lot longer.

And that they would do. The problem the people who assume they are a miracle cure are disappointed. And there can be a noise issue at night with them.

As they are mounted inside the hull and can be turned off, you wouldn't know if one was there.

The article says the range of the transducers is 40 to 50' in water and is dampened by being mounted to the hull.

Just wonder if you would get an acceptable positive effect if you just hung them overboard like you do with fenders except into the water.

I tend to get a little more information from my customers than just a boat name and slip number. If any of them were using an ultrasonic anti fouling system, I'd know about it.

That doesn't seem too likely. If it were the case, why wouldn't they be marketed that way?

It's the vibrations they transmit to the hull, fittings, etc. that inhibits the growth. Not just the sound/noise alone.

Have a couple install at the boat rental company I work for. Will keep hard growth at bay but not soft growth. Boat maybe out for two weeks or less. Comes back with grass,slime no to few shells. I'm not sold on it but the boss wanted to try it.
