ultrasonic antifouling?

[sailingdog]

Your logic is faulty... there are a LOT OF PEOPLE using watermakers... Just because you're one that isn't doesn't mean jack. How many people do you know using ultrasonic antifouling??? Their webpage has so many caveats about what could cause it to fail as to be almost worthless.

From their FAQ page:

Does Smart-Antifouling M20 work on all boats ?
Smart-Antifouling M20 works on 90 percent of boats in the marketplace, with very few rare exceptions. It does not work on the very rare boats built with cored fiberglass hulls or solid bottoms in excess of 25mm / 1” thickness. Smart-Antifouling M20 is also limited in metal hulls, steel or Aluminium to a maximum plate thickness of 6mm - 1/4 inch. Special consideration must be given to installation in hulls which feature an over-abundance of structural members including heavy frames, ribs or longitudinal stringers.

Now, a lot of boats I've seen have cored fiberglass hulls... and they're not all that rare. I've also seen a lot of older boats with hulls thicker than 1". I've also seen a lot of metal boats that have hulls thicker than a 1/4". Then they have the catch all of "Special consideration"... which basically eliminates a lot of other boats.... so what boats does it work on??? 90% of the boats that don't meet the criteria above...

Finally, if their product really worked, don't you think they'd offer a money-back guarantee or warranty of some sort. They don't warranty or guarantee performance at all. Again, from their FAQ page:

What is the life expectancy of the system ?
The control unit and the transducer are encapsulated to ensure a long life, the best material, design and production standards are ultilized to ensure a long time use. Be careful to avoid cable chafing which could potentially prevent the system from operating at its full potential or short the components, we fully guarantee the system for one year from the date of purchase against mechanical defect, provided the system is correctly installed.

Note, nothing about performance or effectiveness is guaranteed, just mechanical defects....

I don't use a watermarker, therefore watermakers don't work. Duh.

OK let me put this to rest so all of you understand this very very clearly... As a once seller of these products on this antifouling technology I can tell you for certain that it absolutely does NOT WORK... I have developed instruments for testing this and have tested it on 12 boats of varies sizes and shapes spending alot of time and money. These Products do not work do not be taken in on the hopes that this will work. I believe the people thinking it is working are just hoping and believe it is working. I have even tested the units with different materials in the water and the unit itself grew barnacles on it. What does that tell you!... My tests where all conducted in the ocean not on lakes or ponds so I can only speak for this technology in the ocean. I am sure this will stir up more debates but these are the facts and I have all the documentation and shrinking bank account that proves it. SORRY FOLKS I wanted it to work, I would have gotten Rich!
