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 fields, such as a compass, a
battery, high current wiring, an electric motor
and a radio or radar transmitter or antenna.
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:

71 mm, (2.8")
97 mm, (3.8")
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).
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:
At least 1 m (3 ft)
