panel fronts, but their much more complicated back-
sides as well. A spray can containing a protective
silicone solution or a preserving, penetrating oil
is very handy indeed, and at least twice a year all
exposed metal parts in the electrical system should
be given a thin, protective layer of such a spray.
Spray all connections behind the instrument panels,
and spray all terminals and connections behind
the fuse panel.
e) Bonding - protection against corrosion
It will be observed that particular attention has
been paid to the corrosion problem, and numerous
precautions have been taken to protect against
electrolysis and/ or galvanic corrosion.
As is accepted standard, the D.C. electrical system
has negative grounding. All through-hull fittings
are thoroughly bonded, and all underwater parts are
made of the same or compatible alloys. We would
like to stress that no metal parts should be fitted
to any wet surface of the hull unless bonding is
provided. The bonding is done by interconnecting
all through-hull fittings, engine framing, stern tube
etc., by means of heavy gauge copper strip to
eliminate any electrical potential which may exist
between the various metal fittings in contact with
the current-transporting salt water.
4) The fire extinguishers
Paragraph 3.9 describes the location of the two
manually operated fire extinguishers fitted at the
yard.
As FJORD MS 33 is a purely diesel-engined boat,
carrying nothing but diesel fuel on board except
for small amounts of alcohol for the stove, the two
dry powder extinguishers are considered to be
sufficient in any situation.
The extinguishers have very comprehensive instruc-
tions for operating and maintenance printed directly
on their containers, and these instructions should
be read with care. It is imperative that one be
familiar with how to use the extinguishers, and
that they may be activated within seconds if
necessary. Of course the extinguishers do not
contribute to safety unless they are continuously
kept in order. They must. therefore, be regularly
checked according to the instructions.
5) The steering system

cable design is fitted in Version A, a hydraulic
