G-PILOT 3100 

Operation Manual

NAVMAN

 

8

4    It is possible to change the steering mode 

during a voyage, for example:

      Change from GPS to compass at the 

end of a route.

      On a sailing boat, change from wind 

to compass or GPS when changing 
from sail to motor (see section 3-4).

5    The G-PILOT can be adjusted to optimize 

its steering performance:

      If necessary, adjust the turn rate so 

that the boat turns at a reasonable 
rate; go to TURN RATE in the 
OPTIONS menu (see section 3-7).

      Select a profi le suitable for the 

conditions (see section 7-2).

      If necessary, adjust the data in 

the profi le to improve the steering 
performance (see section 7-3).

      If the G-PILOT steering performance 

is poor and the above adjustments do 
not correct the performance, consider 
performing a complete dockside 
setup and sea trial as described in the 

G-PILOT 3100 Installation manual

Important: 

      The G-PILOT cannot control the boat 

better than a helmsman. The G-PILOT is 

not intended for use in extreme weather, 
in adverse conditions or near other boats, 
dangerous waters or land. In these 
conditions, disengage the G-PILOT and 
steer manually.

      Never leave the helm unattended, keep a 

watch at all times and be ready to resume 
steering the boat manually.

      Do not try to turn the rudder by hand 

when the G-PILOT is engaged.

      Local variations in magnetic fi eld can 

affect the accuracy of the compass 
heading. Such variations are the 
responsibility of the user.

2-3-3 Action in an emergency

To regain control of the boat in an emergency 
situation:

      Either press 

AUTO

 to put the 

G-PILOT 3100 in STBY (standby)

      or turn the power switch(es) off.

Then manually steer the boat.

2-3-4 Turning the G-PILOT 3100 off

It is normal to turn the G-PILOT off upon 
reaching your destination.

2-4 Setting the steering mode

The G-PILOT 3100 has three ways to steer 
the boat: 

compass

GPS

 or 

wind

. These are 

called the steering modes.

For a power boat

      For a boat without GPS, or for a boat 

with GPS when you do not want to navi-
gate to a waypoint, choose 

compass

 

mode. The G-PILOT 3100 steers the 
boat at a set compass heading. 

      To use the G-PILOT 3100 with a GPS to 

navigate to a waypoint or along a route, 
choose 

GPS

 mode. The G-PILOT 3100 

steers the boat using navigation data 
from the GPS. 

For a sailing boat

      To sail, tack and gybe at a set angle 

to the wind, choose 

wind

 mode. Wind 

mode requires a wind instrument, such as 
Navman’s WIND 3100 to be connected 
via NavBus or NMEA.

      To steer to a set compass heading, 

choose 

compass

 mode.  

      To use the G-PILOT 3100 with a GPS to 

navigate to a waypoint or along a route, 
choose 

GPS

 mode. 

Note for sailing boats

      The G-PILOT is not recommended for 

use in light, changeable or gusty winds.

      Take care when running to avoid an ac-

cidental gybe.  

      Wind mode requires the wind instrument 

to be accurately calibrated.
