Pix of boat:

in 2010, unlaunched, newly applied Coppercoat.
Today, 2011, lifted and jet washed, about 3 hrs later
And a close up.

Pleased as punch not to have to antifoul before she goes back in, in a week's time.

If that's your old Twister in the background I'm surprised you don't get agoraphobia on the new one :D

I would be more worried that the copercoat has dissolved the mast even before it was put in the water.

No burnishing says Mr Coppercoat. Maintains that was a rumour started by conventional a/f mfgs.

Mast not dissolved. That's it being rigged in foreground of 1st pic.

Yes, Indigo in background. Now happily plugging mud in Bradwell.

this is what they wrote to me in 2010:

While Coppercoat offers a strong degree of protection against most fouling in
most locations for many years - it is not a "maintenance-free" product and
periodic cleaning of the hull should be expected. Of course, the benefit is that
unlike with conventional anti-foul, once the hull has been cleaned you can
simply re-launch and do not need to go through the expense and rigmarole of
having to apply yet another coat of anti-foul. There is also the environmental
benefit of not washing and scraping off old anti-foul paint every season - as is
commonly required.

My final piece of advice is that when the boat is out of the water you may
benefit from lightly but thoroughly burnishing the surface of the Coppercoat,
using a fine grade of wet-and-dry paper or a finishing sanding pad. This will
expose fresh copper and increase the rate at which the copper oxidizes and
becomes more active (in an anti-fouling sense). Do not use anything coarse, as
the idea is to burnish/polish the surface, not abrade it to give a good key for
marine life to cling too!!! In most locations this burnishing, but is a process
that may be beneficial to your boat in your current location.

I hope that this proves useful and please feel free to contact me again should
your require further advice.

With best regards,

Ewan Clark.

I like the idea but it's expensive.

I have found somebody who does it for me each year for about 150€ plus price of antifoul. (approx €50) Liftout and back last year was €65.

Speaking of colour, why is there a band of lighter green below the waterline?

My guess is that shows you where the actual waterline is. Since it's more exposed to the air the copper has oxidized more than what is continuously submerged, hence the more prounounced green band.


To be honest though, antifoul generally looks fairly good after being blasted clean with a pressure washer. What did it look like when it was fresh out of the water?

Grrrr. Dunno. Yard was scheduled to lift at 1130 when I was there. "Oh well, we had this slot at 0830, so we lifted her then."

According to the bloke... just the usual for coppercoat, bit of slime, could have wiped it off with a rag.

Indeed there were a few bits the blaster had missed which I wiped off easily, although they were 90% dry by then.

No hanging gardens, no shells, no barnies, no mussels. 13 months of my usual Tiger Extra and there would have been plenty of that.
