3. STEERING MODES 

The NAVpilot-511/520’s AUTO mode steers the boat automatically on a course 
set by the operator. 
 
Note: The AUTO mode will not compensate for the effects of wind or tide, which 

can push you off course in the athwart ship direction. Use the AUTO mode 
for short, straight voyages. Otherwise switch to the NAV mode which is 
described on page 3-4. 

 
1.  Direct the boat to the intended course desired. 
2.  Press the [AUTO] key to activate the Auto mode.   

Your boat will automatically maintain the current course at the moment the 
[AUTO] key is pressed. 

Whenever the heading deviates from the set course, the NAVpilot-511/520 
automatically adjusts the rudder to return the boat to the set course. 

3.  To change or readjust the course setting in the AUTO mode, simply rotate the 

course control knob to the desired course. 

4.  Press the [STBY] key to leave AUTO steering in an emergency. You can 

steer your boat by the helm.
