Interesting experiences and comments
with marine growth on props, struts, shafts. The problem I have
is not so much barnacles, but mussels. As Martin said, "mussels attach with a self created
fiber."
For the past 3 months, I have been praising Micron 66 for its
effectiveness of preventing marine growth. Dwight suggested
applying 66 to the prop. It is worth the try and here's one
reason why I think so.
Since 2006, I have used Micron CSC .....every thruhull was painted
with CSC up a few inches with a foam brush....yet mussels grew in
the thruhulls.....last year, the thruhull openings were painted
with Micron 66......mussel growth was almost none existent.
Something in the Micron 66 appears to be effective inhibiting
mussel growth.
So, I am going to paint the prop with Micron 66.....what have I
got to loose.....a little paint.
Wish I could paint the bottom of my keel with 66 as well....boat
is in a cradle with the bottom of the keel sitting on a big piece
of wood......we don't use a travel lift.
Any suggestions on how to paint the keel bottom?

I had my 30' race-boat's bottom cleaned every week
starting in August in Newport, RI. That's when the water starts to
get pretty warm. Prior to that I had it done every two weeks. Just
a quick wipe with a towel keeps the Pettit Vivid nice and clean.
No prop to worry about.
Now that I have the C&C, I'm avidly reading the solutions to
barnacles here, and leaning toward the Pettit Zinc spray. This has
been an excellent thread.

A local, avid
Soverel 33 racer built a boat sized underwater
enclosure (float at top, weighted at bottom) into
his Shilshole Bay Marina slip. After a race he will
pour a little bleach into the enclosure to reduce
marine growth. I’m not sure if the bleach or if the
controlled environment (less light and nutrients) is
the more effective element of this strategy.
Getting in and out
of the enclosure is troublesome but he swears by the
effectiveness. Based on his light air racing
success he may be on to something.

Here
in Erie When the Zebra Mussels first came on
strong, they were a huge problem for the water
authority, now the inject Chlorine at the
intake, then remove it with carbon at the plant,
at least that is my understanding of it.
Chlorine
is something I don’t mess with anymore. I put a
pellet in my Shurflo refrigeration strainer and
it ate the 316 SS 50 micron mesh right up! Now
I use Moth Balls. They don’t allow any growth
in the strainer, but unfortunately they do allow
the fry to pass downstream. I would suggest
grinding up moth balls into a powder and mixing
them up into your favorite bottom paint. May not
work, but –
it
can’t hurt,
there’re
inert!

Martin,
In answer to your last question, What
do the local power generation and
utilities use to keep intake and
discharges clear?
The answer is divers!! Nothing else
will keep some intakes clear, no
matter
what coating or treatment is used.

I suspect that the broad difference in
prop anti fouling coating performance
relates to the way sea creatures
attach to the prop.
Here in the PNW, at Shilshole Bay
Marina, barnacles are the problem not
mussels. Even when the zinc paint is
wearing out a light brush will remove
any that remain after applying power
to the prop for a few minutes.
The zinc paint seems to kill the
barnacles or at least prevent them
from
attaching to the coating.
IIRC mussels attach with a self
created fiber. Barnacles seem to grow
onto
the substrate with a softer foot or
base which may be easier to poison.
What do the local power generation and
utilities use to keep intake and
discharges clear?
