Transition Speed set to 9 Knots

Transition to LO parameters

Transition to HI parameters
with decreasing speed: 8 Knots

Speed

 

Sailboat 

When sailing in WIND mode, the parameters are automatically 
changed by the direction of the wind as per below or by the boat 
speed. 

 

The transition between HI and LO parameters and vice versa 
will have a different characteristics with regards to the wind 
angle compared with the transition controlled by the speed of the 
boat. 
If you loose too much speed e.g. when tacking, the parameters 
will change to HI to gain sufficient rudder response. This should 
be observed when setting the transition speed on sailboats. 

2.10

 

Manual Selection of HI/LO Parameters 

Manual selection of HI/LO parameters is necessary if there is no 
speed input to the autopilot or if you want to override the 
automatic control. 
To toggle between LO and HI parameters, press the "AUTO" 
button two times quickly.
