Location
Mount the compass:
At least 1 m (3 ft) away from any steel or
iron boat part, such as:
a steel hull, deck, cabin or steel
reinforcing in ferro-cement hulls
steel equipment such as motors and
cooking equipment
places where steel objects are stored,
such as the anchor locker and storage
lockers
At least 2 m (6 ft) away from equipment
with a magnet and equipment which
generates electromagnetic fi elds, such as
a compass, a battery, high current wiring,
an electric motor and a radio or radar
transmitter or antenna.
As close as possible to the centre of
movement of the boat, to minimise how
much the compass moves when the boat
rocks and pitches. If the compass can not
be mounted at the centre of movement, it
is usually best to mount the compass as
low as possible.
On a vertical panel which does not
vibrate.
The unit is completely waterproof but should
not be immersed. The compass is not
affected by other metals, such as stainless
steel, copper or brass. Follow the location
guide (see section 3-2-1).
Fibreglass or wood hull and cabin: mount compass at the centre of movement (for planing hulls,
the centre of movement is usually close to the stern):
Steel hull, non-steel cabin: mount compass
1 m, (3 ft) above hull:
Steel hull and steel cabin: mount compass
on a pole 1 m (3 ft) above the hull and at
least 1 m (3 ft) from the cabin:
1 m (3 ft)
