The canal I was in connects the city of Goes in Zeeland to the
Oosterschelde, which is salt and tidal, and so is the canal. The
Oosterschelde has a world famous series of (some 22)concrete doors
across the mouth of the estuarium to close it at spring tides and
extreme westerlies. This is to prevent the disaster of February
1953, a spring tide combined with westerly winds, taking the lives
of 1800 persons and thousends of cattle. The whole province Zeeland
was flooded. So far the free Dutch history and geography lesson.
I’m going to check on the internal anode as soon as I’ve found and
reached it. My heat exchanger was nice and clean inside.

I think you should go with Alan’s suggestion, and take up electric
boating whilst you are in
the canals!

Help needed
After reading about the subject of bonding, corrosion and zincs,
I
had a look at the situation today. The two magnesium anodes were
clean and pitted, the zincs were covered in white sodium-
something
and the antifouling paint had peeled off the stainless steel P-
strut. No stray currents but a textbook example of
overprotection by
too much zinc or worse, magnesium. I forgot that this boat has
lived
in the salty and warm waters of the Gulf and now moved to the
colder
and less salty waters of North Western Europe. I removed the
magnesiums and will replace them for one small zinc. I will also
remove one of the zincs on the propshaft and see if the balance
between kathode and anode is better.

Hi all,
After being on shore for 7 months, my F44 went back in the
water
like new a month ago. Today she was hauled again and guess
what?
All 5 new anodes (2 magnesium on the strut, 2 zinc on the
shaft, 1
zinc on the rudder connected to the rudder shaft) were heavily
corroded! From the shaft towards the rudder, the corrosion
seems
to
worsen.
The boat was in a fresh water canal without steel pilings, I
had
never connected shore power (we have 230v here, and the boat
is
still 110v). I only ran the generator with battery
charger/inverter
for a few hours every friday (three times).
My house batteries were completeley depleted while on shore,
the
generator battery (separate) was still okay.
Where could this problem originate? (obviously the
generator…)
but
which connection is wrong??
There is a bonding wire running to the rudder quadrant; would
that
be the culprit? I don’t know yet where this wire leads to.
Thanks for your help and suggestions!

Michel,
Please send those Dutchmen to New Orleans to teach our engineers how to protect against storms.

There has been a Dutch delegation over to Nawlins to advise. US
politics however prevents foreign contractors to do much actual work
there, so the learning curve is not very steep. I was surprised to
learn that the US coast defence (against the sea, not the Enemy) is
in the hands of the Army (or Navy, or Marine) Corps of Engineers. In
our country we have a non-military agency responsible for this since
1798.

Fellow sailors,
In our country (US of A) we must be ever vigilant to possible attacks from Al Qaida. This is why we depend on the knowledge and talents of the Army Corps of Engineers. Unless…of course if Hallibuton bids unopposed for the job. Need any US $ for tulip research? or for developing energy efficient red light bulbs over there in Holland? I’m sure we have a lobby group available in Washington to assist you! (just kidding NSA, if you are reading this)
