Copper ring report
 

Last spring I took up a bit too soon on the new through hull nut for
my Knotlog sensor and set it a bit below the surface of the hull.
Attempting to make lemonade out of lemons and kill another bird with
the same stone while excelling at creative writing by avoiding trite
sayings, I cut a ring of copper flashing and epoxied it to the through
hull surface thus:

http://home.maine.rr.com/rlma/Strider0604.htm#Copper

I took the sensor out for the first time today to check it and there
is not a hint of slime or growth on it. Last year it had small mussels
with discernable shells growing on it by August.

I think this really works. I wonder if there is some way to copper
sheath a fiberglass hull:)?

I know taking it out more often and putting it in a fresh water with a
bit of bleach is another approach but mine was cleverly installed so
that the fastest swap with the blank plug still results in a jet of
salt water all over the cabin sole and some drawer hardware. It's
enough of a clean up that I'd like to not do it more than a couple
times a season.

I remember reading of a company that installed some sort of copper foil to
the hull, but that was a few years ago. It wa expensive IIRC, but did last a
long time.

I have wondered about fitting some sheet copper to the bottom of the keel,
because for some strange reason, bottom paint never seems to last as long
there.

You have to stop using the keel to locate the bottom. :-)

Copper bottoms were fitted to Royal Navy (wooden) ships.

Then a scientist came up with an electrolytic method to stop the
copper eroding. The Navy loved it.
For a few months.
They found that cathodic protection saved the copper, but allowed the
marine growth to come back with a bang!

Hello Wayne, Do you still have any info on the Islander Bahama 24?

Sure. Bottom paint.

I think he mean International Hard Racing Copper Antifouling.

Are we still allowed to use it? In fact is copper-based antifouling not
banned, along with everything else? Over here TBT (TriButylTin) was banned
for pleasure craft years ago, and I seem to remember copper-based paint was
also banned, but could be mistaken.

And, if we sheath the whole thing, we'll have enough electrolysis current
to charge the batteries!.....(c;

Not really.

What kind of information are you looking for?

Anything you might have or know about the boat.

You might want to look at coppercoat.com or c-guard.co.uk which offer a
hard epoxy-based paint with a very high copper content. I am about to
apply coppercoat on my boat. It is supposed to be good for ten years
or more.

Thanks a bunch Wayne, great info. I am trying to track down some
original paper work or manuals if possible.

You want to thank Dave. I agree on the motor well, they must be
ventilated in some way with the out board running.

Thanks Dave, ventilation is not a problem for me, as my motor hangs
off the stern of my boat. Thanks again for the info.

If anyone is interested I have just run across a Ceramic based paint
that does not allow bottom growth. It has been tested in Florida where
growth is known to grow fast. After applied growth disappears as soon
as the vessel is under way. Please let me know if you are interested.
Samples are available.

Is coppercoat legal in US waters? I note that they do not have a US
distributor.

Yes, I'm interested in the Ceramic based paint. Please let us know the
details.

Reading the report, I sure wish they'd tested with "ordinary" bottom
paints as controls.

All I really got out of this report is that the more often you clean
your bottom (who dives their boat 2 or more times a month????) the
better it keeps stuff off.

Duh.

PS in a past life I was part of a demonstration project. The
government usually has huge controls, great oversight, and enormously
tedious reporting. This demonstration project was amazingly small...

Yeah, I'd like to see a link to the paint in question...

AFAIK, CopperCoat is legal in the US. The mfg said that they are in
negotiations with a US-based distributor, but currently do not have one.
