BASIC PRINCIPLES

lollowing 

2000’s principle of operalion will help you
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.
Under 

 2000 

course is 

 and

 lo apply 

 rudder 

 in 

vessel 

 lo 

 treading.

Aulomalic lrimming capability ensures

that 

 originally sel course is held

irrespective of any changes in balance

 may occur during 

 course    a

passage.

The Aulohelm 2000’s computer also

continuously monilors 

 pallern of

applied rudder 

 and can

distinguish unnecessary repetilive
corrections caused by 

 and roll 

 vessel lrom those necessary 

IO

rnainlain 

 heading.

The computer will automatically

, 

 all unnecessary 

 so

 aulopilol 

 and power

 is 

 oplimised

al minimum levels.

The high degree of control aulomalion

made possible by the micro 

 user control lo a series   push
