Hi Bruce,

I epoxied a solid copper ring around the through hull for my transducer when
I set the flush fitting a bit too deep. I figgured that would be that cat's
pajamas but it slimes up and the long slime threads jamb the paddle wheel
just about as fast as bare fiberglass would. No barnacles grow on the ring
but the grow briskly on the bare plastic paddle wheel 1/16 inch away from
the copper.

If I had coppered the whole boat, I would expect to need to scrub it every
month even up here in Maine where fouling is light. I now paint the copper
ring just like the rest of the bottom.


I'll let you in on a secret. Take the damned speed log transmitter
out, plug the hole and use the GPS. No more barnacles on the paddle
wheel. You do need some penlight batteries but that is easier then
jumping over the side in September to scrape the paddle wheel, or
having to pull the damned thing and sea water squirting all over the
electrics.

Heck, I used to sail from Muscungus bay up to S.W. Harbor with a
compass and one chart. Just head north out of Muscongus bay till you
can't see any land out the port side and turn left. Keep going 'till
you see one of those little white boats and just drift on by and
holler "Where am I?". You may get told, "You're out in a boat", but
most of the time they'll tell you where you are. :-)

Yup, that's the guy - known as the "Chemical man".

Greetings Bruce,
I use Jotan and merely add between 5 to 10% TBT - usually 5%. I was
told not to use more than 10 percent as it will affect the drying and
adhesion of the antifouling. It works well for me. Of course some of
the problems people may have experienced may have been applying the
wrong anitfouling ove and existing layer. I know when I started using
Jotan in Malaysia instead of ABC-3, I had to sand back hard and apply
a Jotan primer coat. - But you and they would have thought of that
aspect.

cheers
Peter



I've been leaning that way. Met a fella today who's mate painted boats
for some years and he makes about the same recommendation you do.

I'm beginning to think that the people that had problems were using
too much TBT as much as 10% by volume, or more.

the more research I do the lower down the scale the TBT addition seems
to be. Right now I'm getting recommendations between 3 - 5 % and not
more.

I must have the remnants of 15 years of anti fouling on the bottom so
this time I';m going to scrape it all off, prime and a tie coat and a
couple of coats of bottom paint. Probably be 5 knots faster :-)

Yes, Mr Ong of Langtrau Traders.

Now in his 80's and speaking perfect Oxford English (though I wouldn't
expect that you as an American would appreciate well spoken English),
he has had a very interesting life. His father died when he was 9
leaving his mother to scrape a living for the family unassisted. When
the Japanese occupied Malaya, they set up a medical school at Melaka
and he was chosen to attend. After his 3rd year the British returned
and the school was closed down, thus terminating his medical studies.
Returning to Penang his Doctor friends suggested that, as drugs and
medical supplies were hard to get hold of, he should think of buying
them in Singapore on the black market and smuggling them back to
Penang (the best city in the universe where the most beautiful women
are just that - women) where they would buy them off him.

Subsequently he somehow obtained a military uniform and a weekly pass
(forged or otherwise acquired) and made the weekly round trip by
train. At the time Singapore was a military area and was no go to just
anybody. He went on to found the largest chemical company in Malaysia
and when he reached his 60's retired, handed it over to his sons and
started selling all kinds of chemical supplies from that shop house.

He is an easy person to make any excuse to sit and have a cup of tea
with and just ask questions. The prices of his TBT and other useful
boaties' chemicals is ridiculously low.

I was planning to leave Curacao today bound for Panama and have only
just found out that there is at least an 8 week delay for transiting
the canal. Only 3 yachts are allowed transit each way on 3 days per
week. This delay means that I would have to go hell for leather to
reach your end of the world before the cyclone season starts in
November - and with La Nina.... I am thinking of heading home for a
few months. Damn!!

Asalaam
Peter

You make it sound simple but I have taken all the a/f off a 34' boat and it
is not an experience I ever plan to repeat.
I used a paint remover that was guaranteed not to harm fibreglass and it did
not , but this meant it was not all that brilliant at dissolving paint
either.
It left behind some thin residues which I washed off with the thinners
appropriate to the a/f. We used a lot of it and although the job was done in
the open air we were seriously affected by the fumes.
Get a (really) experienced professional firm to sand blast it off in
controlled conditions. .

I'm told that if you use a canal agent the delay can sometimes be
reduced to days. Apparently they reserve slots in advance ($$$). I
know of several trawlers that have gone through recently with minimal
delays.

There is really no excuse for not carrying a spare hand held or two
and a few extra batteries. I use them in the dinghy at times.

So I've heard but both from two agents and 7 yachts who reported back,
this is definitely not happening for yachts. One agent said that
people were even trucking their boats across by road which is
reported to be not a good one. This stopped when the triler broke on
one such trip and the yacht fell off.

I do but that's not what I was talking about. Someday, the airforce is
going to detect an unidentifiable radar target and turn the whole system off
just in case it is a poor mans GPS guided missile.


Supposedly there is some new invention called a "sex tent" or some
such which uses heavenly bodies to determine position without
satellites or radio waves. What will they think of next ?
