BASIC PRINCIPLES

lo make lull use ils advanced lealures.
The powerful of a
compass and microprocessor
provides ‘aulolock’ course selection
wilh precise course
adjuslmenl.
Deviation from course is continuously
monilored by a sensitive
compass and rudder is
applied lo relurn vessel lo course.
The applied rudder is proporlional lo
course error al any lime and lhus when
course is restored rudder will be
neulralised.
When changes in vessel lrim occur
due lo varialions in wind pressure or
engine selling course can
only be rnainlained by
permanenl rudder (standing helm)
lo reslore balance. II permanenl rudder
is nol applied lo restore balance
the vessel will bear on lo a new heading.

course is and
lo apply rudder
in
vessel lo treading.

that originally sel course is held
irrespective of any changes in balance
may occur during course a
passage.
