Yet another electronic anti-fouling

There was a thread a while ago about electrical anti-fouling, with two copper rods and a control box. Here's another implementation of the same technology. TCM Asia electronic anti fouling Although this one seems more thought through I remain sceptical.

Yes, this is another shot at that same concept as we saw before. It may be a more elegant way to do the same thing. I have a problem with way and location of the electrodes being attached. It seems almost impossible to not bump the bottom and not cut off the electrode along the keel. The power requirements were not well indicated nor the issues of galvanic corrosion. I'm no less skeptical than I was with the other approach.

Don't ask if you can't handle it

I work in chemical water treatment for corrosion/scale/biological control; there have been/are many of these type systems floating around the industry for years. But overall they all have a poor track record. If they wouldn't work in just a normal cooling water systems what is the odds it is going to work in saltwater world of corrosion etc? I doubt that any of them even really got a R&D budget of note to develop.

I keep telling you all I have a system with just some wires and rods that will connect to a couple of batteries so it is easy to install and can be had for 1/2 the price of these units

I don't understand how that wouldn't eat up your through hulls, prop, prop shaft, etc... how they isolated?

Every wonder why birds can sit on a 12,000 volt power line and not die? It is because there is no current (electrons) flowing through their bodies.

I imagine the same exact thing would happen to any biological fouling that wants to attach itself to your hull...even if you hooked up the electrical output of a nuclear power plant to your hull.

Any sort of cathode (by convention and not electron flow) you hang over your hull is going to send current straight to ground first and not to something attached to your hull first and then to ground, anode, negative or neutral....whichever the case may be.

Electricity takes the path of least resistance which will not be through fouling first. Interesting idea, but fouling is not a resistor/load in a closed circuit.

In 1993 I specified the first Cathelco system to be put on a Feadship to manage any growth within the salt water pipe-works.

After 10 years of operation I can confirm it worked perfectly and it is now pretty much a specification standard to manage barnacle growth in the pipes.

The system for protecting the hull is a lot more complicated (and expensive), but then again, so is the cost of paint, anodes and haul-out for those big yachts.
