Rudder 
Rudder sets the rudder gain, which is the ratio between the 
commanded angle and the heading error (p-factor). The default 
value depends on the boat length. The value (ranging between 
0.05 and 4.00) is determined during Sea trial (see page 140), but 
can easily be adjusted in the User Set-up menu. 
Counter Rudder 
Counter Rudder is the parameter that counteracts the effect of 
the boat’s turn rate and inertia. The default value depends on the 
boat length. The value (ranging between 0.05 and 8.00) is 
determined during Sea trial (see page 141) but can easily be 
adjusted in the User Set-up menu. 

 

Same procedure as in STANDBY mode. 

Off Heading Lim 
Off Heading Lim sets the limit for the Off Heading Alarm. An 
alarm occurs when the actual heading deviates from the set 
heading more than the selected limit. The default setting is 10° 
and the range is 3 to 35°. 

Turn Mode 
Select either Rate of Turn (ROT) steering or Radius (RAD) 
steering. ROT is the default setting. 
ROT/RAD 
ROT/RAD sets the turn value for the selected turn mode.  
The rate of turn range is from 5°/minute to 720°/minute and the 
radius range is 0.01 to 0.99 nautical mile. 
The minimum radius can however, never be less than the value 
corresponding to a Rate of Turn = 720°/minute at the set 
Cruising speed. 
The initial value is determined during Sea trial (see page 138), 
but can easily be adjusted in the User Set-up menu.
