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.
Speed (Man, Log, SOG)
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.
