My point exactly. If they worked, they'd already be in wide use.

I rest my case !





Just kidding... sort of.
Actually, it's not an end all to fouling, but it is interesting that the presence of these units is so offensive to certain people.


If they truly don't work what problem is that to them?

I would think they would be happy to be able to say,



"I told you so."

Re: Ultrasonic antifouling?? any good??

See, you think that I have some sort of problem with ultrasonic anti fouling systems. Quite the contrary. I don't really give a flying f*ck about them because I know that they do not work as advertised and will never become a significant factor in the boat maintenance business. Any post I have ever made here about them is in rebuttal to people making claims about them that I know are simply not credible.

You do your boating in a place where serious fouling is not a concern. But even there, ultrasonic systems are rare. Why is that? You have never addressed that question.

Following your logic, does that make them bogus also?

Well, fool or not, none of you geniuses have answered my very simple, straightforward question; if it works so well, why are there so few in use?

I'll keep waiting...

Re: Ultrasonic antifouling?? any good??

I'm waiting Nigel Calders longer term review of his system. He has written that he feels his ultrasonic system was "worth it" in just his first year short term. I would suspect there is a wide ranging group of cruiser who would consider his thoughts on the subject more important than a single SF area hull cleaner's.

But I believe that ultrasonic, bottom paint, cleaning, copper coat are all just part of a bottom management approach. They probably all are "worth it" if used together properly. To just say something like ultrasonic or a specific bottom paint or copper coat, doesn't work is a pretty meaningless thing and is just showing IMO a simple minded unwillingness to progress beyond your current experience and a very narrow group of users.

BTW - I have a feeling a lot of ultrasonic systems not working is a combination of people using the "cheap" systems and/or not installing the units correctly.

Give me a break. These systems typically cost less than a bottom job.

Two reasons,
Boaters as a general group are very traditional. Normalcy bias.


Boaters are cheap when it comes to buying something which hasn't been accepted by the majority. We have all seen other products being laughed at for their cost.



A certain "ABYC certified" person comes to mind.




The cost? Give me a break. You can buy a safe for under $100 that will open if you drop it, or you can spend thousands and buy one which will actually do what it's supposed to do. Keep your stuff SAFE.

And in SF how much is that! So give everyone else a break on the subject as they all know your position from every time anyone asks it. Consider the world is bigger than your little bay.

Maybe wide spread use would make you job easier. Just getting the slim and grass off no barnacles'.

Re: Ultrasonic antifouling?? any good??

Fstbttms may have a dog in this fight and come across to some as self serving, but the boats I've come across with ultrasonic systems onboard while cruising have all had underwhelming results. Some show small improvements, but nothing that I would consider significant or enough for me to want to try an install first hand.

Mine works, I need more time to see how well as it has only been in the water for 15 months in tropical North Queensland. Whether you think it does or doesn’t is of no consequence.
