X axis
= Boat speed in knots
Y axis
= Arrival circle, radius in 1/100 Nm
Example: With the speed of 20 knots you should use a waypoint circle with radius 0.09 Nm.
Ú
Note:
The distance between any waypoints in a route must not be smaller than the radius of
the waypoint arrival circle.
WIND mode
Ú
Note:
The WIND mode is only available if the system has been set up for sailboat in the
Autopilot Commissioning dialog.
Before the WIND mode is started it must be verified that valid input from wind transducer is
available.
Initiate wind steering as follows;
1.
Switch the Autopilot to AUTO mode
2.
Adjust the boat heading until wind angle is according to the angle you want to maintain
3.
Select the mode indication in the autopilot controller to activate the autopilot menu, and
select WIND mode
The set course to steer (CTS) and set wind angle are entered from the compass heading and
the wind transducer at the moment the WIND mode is selected. From that point the
autopilot changes the course to maintain the wind angle as the wind direction may change.
Tacking in WIND mode
Ú
Note:
The tack function is only available when the system is set up for boat type SAIL in the
Autopilot Commissioning dialog.
Tacking should only be performed into the wind and must be tried out in calm sea
conditions with light wind to find out how it works on your boat. Due to a wide range of
boat characteristics (from cruising to racing boats) the performance of the tack function may
vary from boat to boat.
Tacking in WIND mode as compared to AUTO mode is performed when sailing with
apparent or true wind as the reference. The true wind angle should be less than 90 degrees.
The rate of turn during the tack will be given by the Tack time defined in the sailing
parameter setup. The tack time is also controlled by the speed of the boat to prevent loss of
speed during a tack.
You can initiate the tack function from WIND mode.
When you initiate the tacking, the autopilot immediately mirrors the set wind angle to the
opposite side of the bow.
You can interrupt the tack operation as long as the tack dialog is open by selecting the
opposite tacking direction. When interrupted, the boat returns to the previous set heading.
Gybing
Gybing is possible when the true wind angle is larger than 120°.
The time to make a gybe is determined by the speed of the boat to make it as quick as
possible within control.
Tack and gybe prevent
You should use the autopilot with care when beating and running.
