Mike:
After what I heard on this list this week, when I run out of Micron 66,
heaven forbid, I will use Amercoat ABC 4......and it doesn't cost as
much as Micron CSC.
Still gotta a year to find a new supply of 66....like they say,
necessity is the ??????

If I kept my boat in the northwest Arm I would go with Bob's
experience...use Micron 66 if you can get it...as you know Bob is
quite meticulous about Azura and he follows manufacturer's directions
well...one year he had so much growth on his prop (2 blade fixed) in
late september that the boat had a hard time making headway under
power...the prop was foulded extremley bad...next year Bob asked this
list for advice with his prop fouling issue...I knew he had such good
results with Micron 66 on Azura's bottom so I suggested that if he
didn't mind having a painted black prop before launch rather than
shiny bronze he could just try painting it as well with Micron 66...I
believe he did paint the prop and achieved good results...something
about the critters in the Northwest Arm, very prolific... and somewhat
resitant to normal copper oxide toxins...Micron 66 might just have the
right copper toxins and added biocide for the moment...but those
critters adapt to their environment so this coming season may be
different, anyway you have seen Azura with your own eyes, think you
could expect more than that from any paint. Micon 66, Micron CSC,
Amercoat ABC 4 or???...if you are looking for more speed, look
somewhere esle for bigger gains, the performance of thse paints are
quite similar...if your boat's bottom is in top notch shape go for one
with multiyear ablative properties and do the job once ever 3-4 years
instead of every year, like i do.
The copper oxide content is primarily resposnbile for the higher cost
of some antifouling paints and the better paints often weigh more per
volume due to higher copper oxide content
Yes I use Amercoat ABC 4 and like Mike Amirault says my boat spends
the summer on a mooring right at the head of the Bay, sort of brakish
water, shallow at about 12 feet and warm enough for swimming from mid
june until september...Amercoat works fine for me but I apply a thin
coat (about 2 liters solvent diluted before spring launch every year)
so one gallon does about 2 years...no pressure wash after haulout and
very little prep before application before launch...I have used Micron
CSC, expensive by comparison and no noticebale difference...I use a
very thin layer of black Amercoat over blue Micron CSC and no issues
with adherence...I have noted that Mike's C&C 33 MKII is very slippery
as well

Bob told me about Micron 66 repeatedly and showed me Azura bottom
in December. It is how he described.
I have used Micron CSC, VC Offshore and whatever came on our boat
last year (similar to CSC). I would haul Nut Case at least three
times per year (could use a crane so was cheap). 1^st time would
be mid July at a race week after in water for 1.5 months – bottom
looked clean but scrubbed anyway. 2^nd time Labour day weekend at
beginning September when we brought the boat back to Halifax from
its summer location on Northumberland Strait. There would be some
slime and whatever it is that grows on the flat undersides in a
star shaped pattern. Last haulout would be end of October in
Halifax after sitting on a mooring in NW Arm approx. 150 feet from
Bob’s boat. Would be slime and also grass growing on the vertical
surfaces. This mattered not weather Micron CSC or VC Offshore.
Last year Persistence came with another manufacturer version of
Micron CSC. Was launched in June, hauled mid July to work on
Transducers, hauled Sept 8 to work on propeller shaft, relaunched
Sept 19 and hauled 1^st week November. Was dirty on each haulout.
When I compare my experiences with Bob’s on Azura with Micron 66 I
cannot conceive using Micron CSC. The pain of obtaining Micron 66
has made me consider Ameron ABC #4 because a 1D35 in our area has
been using for 10 years and owners say it is closest thing to
Micron 66 available in Canada. They insist it is closer to Micron
66 in its properties than to Micron CSC.
All of the above are racing paints and that is also a
consideration even though we now sail a Winnebago

I had no complaints using Micron CSC....used it for about 12
years....a few years back, I had the opportunity to buy a few
gallons of Micron 66 for $100 per gallon. I read about its
effectiveness in dealing with 'slime'.....the biocides in it I
guess which are not in CSC. And 2 1/2 gallons for $250, how could
I refuse.
AZURA logs close to 1,000nm per season and when the boat is hauled
in October, it does not need a bottom cleaning and/or pressure
wash. The bottom looks pretty much the same as it did when given
a light coat of 66 in the Spring. I have used 66 for 3 seasons
now.....I dilute it about 10% to make rolling it on easier. I am
usually applying antifouling paint around +10C and the little
extra solvent makes rolling it on easier and it the paint seems to
go farther. The boat could go back in the water this Spring with
no attention to the bottom, however, it will get another diluted,
light coat.
A few other club members have witnessed the effectiveness of 66 on
my boat and have switched from whatever they were using. They all
get it when they drive to the USA.
I asked the Binnacle here why they don't carry it......they said
it too much trouble getting all the govt approvals because of the
biocides in the 66.
I don't race AZURA so it really doesn't matter what's on its
bottom as long as it is not mussels and barnacles and other
similar marine growth.

I am in the same marina as Dwight Veniot and I did use
Amercoat #4 for several years. As an antifouling agent it
works very well but I found it to be too ablative for my boat
which sails about 1000nm per season. After a power wash in
the fall, the hull would be nearly bare. Since that time, I
have switched to micron CSC which holds up much better and
sometimes just needs a "brokers" touch up rather than a full
coat each year. Therefore, I think any cost savings you will
get with the Amercoat are offset by justing with CSC.
