Re: Ultrasonic Antifouling Info

FYI- Was informed that PYI, Inc, (distributors of Max Prop etc.) are selling the Sonihull ultrasonic anti fouling system now. Why the eff I'm telling you this I don't know.

The difference is the wagon wheel was demonstrably effective.

Yes. At the time it was. But the evolution continues. Don't worry, you'll always have a job.....somewhere

Re: Ultrasonic Antifouling Info

If I was worried about a decades-old technology that has yet to garner even a fraction of the anti fouling market, I wouldn't have posted the link.

In any profession , particularly, when one earns their living with their hands. The more things you are good at or can offer.the more valuable you become.which translates into more income.if you can adapt you will survive.at least it has worked well for me and a few others......but I already knew you weren't worried.....your postings are clarion.

Re: Ultrasonic Antifouling Info

Ultrasonic Wonder if it might keep whales or sharks away as a by product of fitting one?? Where are our marine study people on this? Every year the Whale population is doubling on the East coast of Australia & more boats are at risk.
Still looking on how to prevent & hating these little pest growing on my hull & props. Issue foam construction!! Maybe solid above the "P" brackets for ultrasonic to work?

Regards Bill

I've been swimming around the boat and though I can hear it, it's quite faint if you're a few meters away. But it could be like a dog whistle...

I'm going to have an long look at our boat in about 2 weeks. That'll be 2 months after installation, and summer is the most prolific growth period. We did one wipe of the slime at + 1 month.

I still think that our approach will continue to be diving, antifouling and the ultrasonics. I'm just hoping the ultrasonics will slow down the barnies so that the boat needs wiping rather than scraping. Early days!

We don't know as it is a secret. I heard somewhere that male bovine excrement is some small percentage of the formula but that's just a rumor.

This is the kind of side-by-side comparison that is meaningful. Looks like the units did their job. So when you install them on your boat, let us know how that works out for you. ;-)

Re: Ultrasonic Antifouling Info

Have not used.
Read tests in practical boat owner, this is an English mag that in my opinion gives honest answers & does thorough tests
They say it helps but is not the answer on its own, still requires anti foul.
If you still have to anti foul then ultrasonics is not worth the high price that they
Are asking

I hope you're basing your decision on more than a video of a "clean" pipe on the bottom of a tugboat on the Mediterranean coast of France.
