Ultrasonic Antifouling

Cypman · 29 August 2009, 16:48

Anybody fitted it, and does it work as advertised? Seems like the right solution to an age old problem, but at a price. But if it works.......

Thanks for the 'heads up', I had seen the previous posts but they do not answer the primary questions of :-
-Have you fitted it?
-Does it work?

At £700-ish, I would also be very interested in this system.
Has anyone got any experience of it?

I have been in contact with Mike Arnold from Blue & Green. Unfortunately it takes approx 1-month between each email for him to respond, so I still have not been able to figure out how such a system could pay for itself nor if it is sturdy enough for a rib.

I also dont know how this would work on the driveleg as the driveleg ( or outboard) is outside the hull on which the transponders are placed.

I use Blakes hard racing antifoul in white and i might as well have not bothered at all. It was newly applied last winter and allready after 2 months i can start all over again. So I am definately in the market for a good solution for antifoul !

My Dads boat has it on, its not rough to touch, even if you lost a few kts I would still use it. Been on my Dads boat for about 8 years now and its spotless, doesn't even need pressure washing when its hauled out.

It's gonna slow you a lot less than a colony of barnacles & weed will!

Thats 15-20 years worth of 'Uno' I think I will stick to the yearly coat as it only takes a couple of hours and the end result is good. It means I can spend more money where I want!!

The Ultra 10 system is £799 +VAT. I am awaiting a reply from the manufacturers regarding its effectiveness on RIBs etc,etc. I will let you know what they say.

£799 + VAT? That's 26 years worth of International's anti fouling for my boat. Frankly, I don't think it'll work.

"copper coat on a rib ?, will it not slow you down too much ? I allways thought that the surface of copper coat is too rough for a fast moving boat, but I have to admit that I have never actually felt it."

I have Coppercoat on my Ribcraft 6.8 (see attached photo). It was put on about a year ago and the hull is spotless. It's not cheap (about £1,000 to have it put on professionally) but it's meant to last at least 10 years so it's definetly worth it in the long run. I haven't noticed any reduction in performance and the hull's smooth to the touch. The only thing is, it's quite tricky to apply so I'd recommend getting a boat yard to do it for you. And don't put it on your outboard or sterndrive leg. Website: www.coppercoat.com

What about trim tabs? Is it anything metallic?
What about the stern ends of your tubes?
Is it only the GRP hull that takes Coppercoat?

GJ0KYZ · 02 September 2009, 09:32

Apparently it can be applied to any hull surface but the people who put it on my boat said they generally avoid engine legs as the proximity of anodes may cause some unwanted electrolytic reactions with the c/coat. They left a one-inch gap on the transom all the way around the outboard's mounting bracket but this is easily cleaned by leaning over the back and using a scrubbing brush.

chewy · 02 September 2009, 09:34

Yiu can't apply it to anything alloy as the copper uses the alloy as a sacrificial anode.

Seamonstie · 02 September 2009, 09:39

Would agree with Chewy, applied Coppercoat to my 6.5 mtr rib 3 years ago, no weed and barnacle free ever since. Once a year power hose the hull and lightly sand the coppercoat again to bring new cooper to surface. Applied it myself after removing all previous antifouling right down to original gel coat. Roll on with four inch roller very thinly, once you start keep going, put new coat on when previous coat becomes tacky, mine took seven coats equal to four kilos of copper. Leave one inch gap around engine.
Tubes done with Gummie paint, also very good.

Intersting information, finally it looks like I know which direction to move. I also thought about putting coopercoat on the tubes but am concerned that it would slow me down and or peel off the tube.

Why did you use Gummie paint, and what kind of paint is this ? why not coppercoat on the tube as well?

chewy · 02 September 2009, 17:54

Coppercoat is an epoxy resin, I think by painting it on the tubes it would fall off giving you a nice tube shaped piece of resin.
