A Word
About
Electrolysis
Electrolysis
is
the
decomposition
of
compounds, such as metals, exposed
to
an electric
curren
L
For
boat
ownen,
electrolysis is a
common
occur-
rence. Using a
shore
power
AC electrical system
on
the
boat includes
an
earth
ground
circuit
that
"grounds" all
onboard
metal parts to the earth
on
shore. This circuit provides
the
protection against hazardous shocks,
but unfortUnately
it
also creates
an
electrolytic
current
which causes the
decomposition
of
all
submerged
metal.
SOLUTIONS
TO
ELECTROL)sIS
IMPORTANT
Damage resulting from electrolytic corrosion
is
not
covered by the warranl}'.
Additional zinc
anodes
may
need
10 be installed
on
your boat as recom-
mended
for your region.
A
zinc
arnxk
is
also used
to
protect
metal
that
is exposed to seawater.
The
salt in seawater causes a galvanic action which decomposes metals. The
dockside wiring receptacle has a zinc anode. Check
it
periodically
and
have
it
replaced
if
necessary
by
your Cruiser Dealer.
A
Ground Circuit Isolator can be installed to prevent
the
flow
of
relatively
low electrolytic currents.
It
will, however, provide a
path
for catastrophic.
short-circuit currents which are sufficient to actuate circuit breakers.
A
5000-6000
volt ampa"es Isolation Transforma-can be installed between the
on·board
AC
electrical system
and
the shore power source.
A Word About
Bonding
Engines installed in non·metallic hulls
do
not
provide shielding
or
ade-
quate grounding. Cruisers uses a
copper
bonding
strip in
the
engine
compartment
to
solve this problem. All metal
pans
of
your
boat
are
bonded
to
this
common
ground
The
AC
and
DC
ground
wires also
meet
at
the bonding strip.
Bonding helps minimize electrolysis. it provides a
common
ground
for
radio
in
terference signals. and it minimizes radio frequency interference
(RF1)
from the boat by connecting
the
metal parts to form a shield.
FRESHWATER SYSTEM
The
freshwater system provides water for drinking
and
bathing. A tank
provides an
on
board supply
of
freshwater.
and
a connection
for
optional
dockside hookup allows you
to
use a continuous supply
of
city water.
The
plumbing provides freshwater to the
head
compartment.
to
the
cockpit
shower. and
to
the sink in
the
galley.
All
freshwater drainage
is
directed
overboard.
