Apparent wind steering is preferred when you want to achieve
maximum boat speed. The autopilot tries to maintain a constant
apparent wind angle to get maximum thrust from a given trim of
the sails.
When sailing in closed waters, the apparent wind angle may change
temporarily due to wind gusts. It may then be preferred to sail to
the true wind.
VMG optimizing
You can optimize the VMG to wind. When selected, the function is
active for 5–10 minutes after a new wind angle has been set and
only when beating.
Layline steering
Layline steering is useful when navigating. Cross Track Error (XTE)
from the navigator keeps the boat on the track line. If the XTE from
the navigator exceeds 0.15 NM, the autopilot calculates the layline
and track towards the waypoint.
Response
By default the system switches between HI/LO parameter set based
on speed (motor boats) or speed and wind (sail boats). You can
however manually select which parameter set that shall be used.
HI or LO must be selected if no speed input is available.
You can manually fine tune each of the two (HI/LO) parameter sets.
Level 4 is default with parameter values as set by the autotune
function. If no autotune is made (not recommended) the level 4
values are the factory default values.
A low response level reduces the rudder activity and provides a
more “loose” steering.
A high response level increases the rudder activity and provides a
more “tight” steering. A too high response level causes the boat to
start lazy-s movements.
Automatic steering
This option displays an overview of all autopilot steering
parameters, and you can adjust parameters if required.
For more details, refer to the separate Vulcan Installation manual.
