ELECTROLYSIS AND GALVANIC PROTECTION

PAGE 30A

Salt water allows electric current to flow from
anodic  to  cathodic  material.  For  any  two
metals  from  two  components,  their  relative
positions  in  the  galvanic  rating  table,  will
determine  which  loses  material  (the  anode)
and  which  remains  largely  undisturbed  (the
cathode).  The  distance  between  the  two
metals on the galvanic table determines the
rate of wear. Thus a sacrificial zinc anode is
often fitted to the underwater area of a boat
to attract any destructive currents away from
bronze or steel propeller shafts, for example.
It is not enough to know that your boat does
not  suffer  from  electrolysis;  a  newcomer  in
the  adjacent  marina  berth  may  start  a  too-

friendly  association  with  metal  components
on it. An easy place to fit an anode is on the
propeller shaft, or covering the propeller nut.
The anode should not be painted; this would
render it ineffective.
To  prevent  electrolysis  in  seawater,  the
difference  between  the  voltages  of  the  two
adjacent  metals  should  not  exceed  0.20  V.
For  example,  zinc  and  carbon  steel  used
together risk corrosion, while lead and active
stainless steel are compatible. Metals with a
high  voltage  corrode  faster  and  need  a
larger  area  to  diffuse  the  electrochemical
reaction.

TEAK CARE (240,260,and 270 ONLY)

Teak  wood  is  a  high  quality,  extremely
durable  wood  with  high  oil  content. In order
to  help  you  protect  the  original  beauty  of
your teak interior, we have sealed the wood
with  a  3  to  4  coat  system  of  high  quality
Seafin  Teak  Oil,  manufactured  by  Dalys.
This material is penetrating oil that dries to a
low sheen to seal and protect the wood from

moisture  and  weathering.  It  creates  a
durable,  nonslip  surface  to  repel  water  and
resist  wear.  It  won

’

t chip, peel or blister. It

reduces

work

and

maintenance

cost

because it is easy to repair and maintain
and repair. With proper maintenance it will
outlive urethane varnish on interior and even
exterior

surfaces

MAINTENENCE

When

oiled

surfaces

require

renewing,  simply  wipe  the  surface
area  free  of  loose  dirt,  dust  or  other
contaminants.  Dampen  a  cloth  with
the  Seafin  Teal  Oil  and  wipe  on.  Let

stand  for  5-15  minutes,  then  polish
dry.  If  your  dinette  table  has  an
epoxy  finish,  clean  with  furniture
polish

REPAIRS

When  woodwork  is  damaged  from  scrapes
or  abrasions  that  go  into  or  thru  the  finish,
take the following steps:

1.  Take  180  to  200  grit  wet/dry  sand  paper
to smooth out rough spots.
2.  Wipe  clean  of  dust  and  dirt  with  a  clean
rag. Note: before applying oil, wood surface
must be dry.
3. Wipe or brush on oil, allow to penetrate 5-
15 minutes while surface is still wet.
4.  Sand  until  smooth  with  400A  wet/dry
sandpaper.
5.  Wipe  dry  with  a  clean  rag.  Allow  8-12
hours drying time.

6.  Apply  second  coat,  sand,  and  repeat
procedure.
This  procedure  may  be  repeated  as  many
times  as  needed  to  bring  damaged  area
back to its original finish. If you have trouble
with getting the same sheen, you may use a
soaked  and  wrung  out  cloth  to apply a very
light coat to get an even sheen.
