Greetings,
Short of any empirical evidence I am very tempted to lump this device/technology in with the magnetic fuel filter device (Algae-X) that purports to kill any "bugs" growing in your diesel.



Maybe, just maybe some noticeable effect was achieved under strict lab conditions and a new "wonder product" was born.

Yeah its says you need it, but if it works, it should inhibit growth in a noticeable way on gel coat between one pontoon and the other over x time. If not, its not working. If so, I'd buy it.


This is such a simple test study. I don't see it having been done anywhere so far (publicly anyways). If I owned the company, the first thing I would have done is run that test, and I'd have photos all over the internet showing/documenting the results if it worked well. I see no real world tests - nothing..


The reality that there's no simple test studies like this readily available on their site after 10+ years tells me a whole lot.


Show us the money!
That test "might" show some insight but many other variables exist as I listed earlier.

While letting a boat sit like a dock might show great results, an occasionally used boat might show so little difference no matter how inexpensive the system, it might be a bad investment.

When we're still asking "does it work" years or decades after a product is introduced, one has to assume it doesn't.

It seems to me, if it were truly effective, every boat in the world would have one by now.

ESPECIALLY in this environmentally conscious world we live in now. Bottom paint is not all that great for the environment.

How often do ocean going freighters and tankers hauled for a bottom job. They often spend weeks at anchor or in ports. I suspect it is rare that they are hauled. So how do they avoid fouling?

two ways ships deal with bottoms..


1. the good stuff we dont get to use anymore.


2. Hull cleaning robots...

By cruising at 25 knots during days Joke apart these cannot be compared with our boat usage...

My first "real" job, 1973 summer between high school and college, was as an electricians helper at Baltimore Dry Dock and Shipbuilding. As low guy on the totem pole one of my jobs was to crawl through the cofferdams down into the bottom of the bilge of big tankers. When down there they would pass me a heated wax type of liquid which I would pour into an electrical box attached to the bottom of the hull. I was told it was to keep it waterproof and that the box put out a small electrical charge to the hull to keep marine growth at bay. I cannot begin to tell you how dirty a job this was, crawling through rust and oil/grease for what seemed like a quarter mile down into the bilge.

He is probably referring to tin based paint.
