Select between Midship or Actual rudder position in Work
mode.
When “Midship” is selected, the autopilot will use zero degrees
as the midship reference. Hence, the rudder will always move
to midship when switching from STANDBY or DODGE mode
to AUTO-WORK or NAV-WORK mode.
When “Actual” is selected, the autopilot will use the current
rudder position as the midship reference (bumpless transfer)
when switching from STANDBY or DODGE mode to AUTO-
WORK, or NAV-WORK.
Note ! “Midship” will always be used when switching to AUTO or
NAV from STBY/NFU/FU.
W Autotrim
Rotate the course knob to turn the Autotrim function off or on
in the AUTO-WORK and NAV-WORK modes.
Autotrim
When the vessel has a constant heading error due to external
forces such as wind and current, the Autotrim function corrects
for this by building up a constant rudder offset.
The value for the Autotrim parameter is the time it is allowed to
calculate the rudder offset.
The Autotrim value can be adjusted from 10 seconds to 400
seconds with the course knob. The default value depends on the
boat length.
