Sorry for the personal mail. The yahoo software doesn't like me for some
reason:

You could always do a test first, to see if it works in your waters. Get
a bit of the Coppercoat and paint it on a square metre board and leave
that in the water. Come back in a month or two and see how it's faring.
If you do the same with another board using your current favourite
antifoul, you'll be able to see what the difference is.

Cheaper and less effort than painting your whole boat as a test!

Cheers, Dave

  This summer I'm renovating a Pearson Ensign daysailer and will be
going with CopperCoat for antifouling.  CopperCoat is non-leeching,
consisting of copper spheres in epoxy, can handle trailering, and
lasts up to 12 years.  From reviews I've read, it either works really
well or not at all.  Since I can always paint over it with regular
paint, I'm going to give it a shot.  Perhaps my home waters will agree
with it.

  I'm also building a 26' plywood power dory, and will doing the
cheap-man's equivalent, adding powdered copper copper from
epoxyusa.com to their basic non-blushing epoxy.

  Assuming I get the boats in the water this summer, I'll post results
in the fall.  I can't be an advocate for either solution, but they're
intriguing enough to warrant an experiment (though not a cheap one).
