I just saw this and was wondering what comments people have.

The December 07 issue of the UK's Practical Boat Owner has detailed
information by the Editor on copper treatment on her own boat that has
lasted 14 years.(pages 6 & 7)

Doesn't seem to be "annealed" or the like but it's stayed on for 14 years
so
it's sure stuck to something.

I suspect that is the "copper Bot" I was talking about. I used the
"Copper Bot" name as I believe it was the first system sold.

=======================
She refers to it as "Coppercoat" with a capital. Apparently, its original
incarnation was Copperbot and its had a name change, though the same company
still makes it. She does mention other disastrous products and I think I
remember one a couple of years ago in the same mag which attracted marine
growth - litigation all round etc etc.

==========================
Out of curiosity, does the owner mention that she has to scrub the
bottom occasionally to uncover new copper?

========================
She said it was recommended but in 14 years she and her husband had never
done it.
========================

She does talk about a small experiment they did on the rudder, painting
three distinct stripes of antifoul x 2 and copper - regretted doing it as
they had to keep renewing the antifoul but never touched the copper.

As an aside. I saw a long slim motor sailor, designed and built by
Sonny Levi (I believe the last boat he owned), in India that had
copper sheet applied to the bottom. It did have some growth the last
time I saw it but Sunny said that you just used a scrubbing pad and
hired a guy to scrub the bottom - no scrapping. Costly though I
reckon.
