I have a feeling a herd of grazing limpets, contained within an electric fence would actually impede your hull performance more than the weed growth in the first place. Back to the drawing board Mr CR.

Reckon you should speak to Graham at GT Marine who does the coppercoat for Paul. He seemed to reckon it was a bit of a PITA and certainly not just a question of a quick powerwash

South Pier Shipyard did Pauls coppercoat and I watched him clean his hull in about 10 mins

And I spoke to Graham about it the other day, he said it's well worth doing

Ok, well the one thing I remember him saying is that every year the copper needs to be "agitated" in order to retain protection, and that that wasn't a particularly enjoyable job.

So what you have to talk to it about absolute zero without mentioning Bose Einstein Condensates? That seemed to get you pretty agitated.

But what if they are trained to retreat to a little box with a remote control sliding lid that also triggers the theme from Moonraker to be played? Then it would be ok.

Coppercoat is a binary product, done well it is brilliant and lasts for years giving great antifouling properties with minimum upkeep. Done less than well and it is worse than useless. Preparation preparation preparation!

Me too, but I've misplaced them, what with the Chaos that is Saint Patrick's Day. I'm getting quite "confused" rather early today - I've just had a vision of Dr. Paul playing a flute, leading his trained rats down Mont St. Michel to graze the foul off his RIB in the carpark...

My Dads got coppercoat on his Aquabell, not the quickest of boats but it doesn't even need pressure washing when it does come out. Some one even thought it was getting launched when it had just been lifted out it was that clean.

Again your commenting on things you know absolutely feck all about, ours has never been "agitated" or sanded and its still working fine.
Its coming out of the water soon so I'll get some pics of it. Think its been applied about ten years and the only maintenance it has had is when the yard insisted on pressure washing it due to H&S, soon put a stop to that. I ran it across some mud once which will have helped clean it too!

I know I'm a bit late on to this thread, but I thought you might be interested to learn what that the founder and owner of NRG Marine (manufacturer of Sonihull ultrasonic anti-foul) uses on his own boat. Answer - Coppercoat! I think that says it all.

Though to be fair, you can't apply Coppercoat to the prop, so by adding the ultrasonic system as well it might help to keep this part clean.

And as the originator of the thread, so do I and have no regrets.

Ewan, just a quick question;- why cant coppercoat be apllied to the sadle of the outboards that sit below the waterline? The only pain now is keeping them clean.

Regards
Steve

Hmmm. Copper bonded to aluminum below the water line? Sounds like a recipe for corrosion...

The problem with using Coppercoat on outboards, brackets, legs, props and so on is one of adhesion. Coppercoat will not bond directly with metal surfaces such as aluminium, stainless steel, bronze or brass.

The only way you can apply Coppercoat to such items is to prime them beforehand with a relevant two-pack epoxy primer. But this is easier said than done, as even these primers do not always adhere very well (and especially not on fast moving parts such as props).

Coppercoat itself is non-conductive and will not cause or promote electrolysis, cathodic decay or galvanic corrosion.

Coppercoat is used on the hulls of large steel and aluminium super-yachts (for example). But on such boats the hulls are coated with several layers of two-pack epoxy and epoxy filler (to a total thickness of many millimeters), and the Coppercoat bonds well with this.
