SYSTEM OPERATIONS-13
A large sacri
fi
cial zinc anode plate is also
attached to the underwater area of the
transom.
The anodes on the rudder, shaft and trim
tabs are installed by your Silverton Dealer.
The purpose of these sacri
fi
cial zinc anodes
is to attract any destructive electrical cur-
rents away from the metallic underwater
components, thereby preventing their even-
tual corrosion and allowing the corrosion of
the sacri
fi
cial zinc anodes. The sacri
fi
cial
zinc anodes are considerably easier and
cheaper to replace and their deterioration
will not affect the performance of your yacht,
as would the deterioration of a propeller or
rudder.
The Bonding System is a network of wires
(color coded green) that are connected to
all metallic underwater components within
the interior of the hull, which makes them
one unit for electrical current purposes.
This network of wires is then attached to the
sacri
fi
cial zinc anode located on the tran-
som, which allows corrosion of the anode,
but prevents corrosion of the underwater
components.
General maintenance of the Bonding Sys-
tem consists of replacement of the sacri
fi
cial
zinc anode located on the transom and all
other zinc anodes located on the propeller
BONDING SYSTEM
The purpose of the
Bonding System
is to
protect your yacht’s underwater components
from electrolysis and galvanic corrosion.
Examples of underwater components would
be the struts, rudders, engine/generator, and
seawater intake valves.
Electrolysis and galvanic corrosion occurs
primarily in salt water, but can occur to a
lesser degree in fresh water. Salt water
allows electric current to
fl
ow from anodic
to cathodic material. Any two metals from
two components and their relative positions
in the galvanic rating table will determine
which metal loses material (anode) and
which metal remains largely undisturbed
(cathode). The distance apart on the gal-
vanic table of the two metals determines
the rate of wear. To help prevent corrosion,
sacri
fi
cial zinc anodes are
fi
tted to the un-
derwater components of your yacht, such as
the propeller shafts and rudders.
