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.

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