G-PILOT 3100 Operation ManualNAVMAN84 It is possible to change the steering modeduring a voyage, for example:Change from GPS to compass at theend of a route.On a sailing boat, change from windto compass or GPS when changingfrom sail to motor (see section 3-4).5 The G-PILOT can be adjusted to optimizeits steering performance:If necessary, adjust the turn rate sothat the boat turns at a reasonablerate; go to TURN RATE in theOPTIONS menu (see section 3-7).Select a profile suitable for theconditions (see section 7-2).If necessary, adjust the data inthe profile to improve the steeringperformance (see section 7-3).If the G-PILOT steering performanceis poor and the above adjustments donot correct the performance, considerperforming a complete docksidesetup and sea trial as described in theG-PILOT 3100 Installation manual.Important:The G-PILOT cannot control the boatbetter than a helmsman. The G-PILOT isnot intended for use in extreme weather,in adverse conditions or near other boats,dangerous waters or land. In theseconditions, disengage the G-PILOT andsteer manually.Never leave the helm unattended, keep awatch at all times and be ready to resumesteering the boat manually.Do not try to turn the rudder by handwhen the G-PILOT is engaged.Local variations in magnetic field canaffect the accuracy of the compassheading. Such variations are theresponsibility of the user.2-3-3 Action in an emergencyTo regain control of the boat in an emergencysituation:Either press AUTO to put theG-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 offIt is normal to turn the G-PILOT off uponreaching your destination.2-4 Setting the steering modeThe G-PILOT 3100 has three ways to steerthe boat: compass, GPS or wind. These arecalled the steering modes.For a power boatFor a boat without GPS, or for a boatwith GPS when you do not want to navi-gate to a waypoint, choose compassmode. The G-PILOT 3100 steers theboat at a set compass heading.To use the G-PILOT 3100 with a GPS tonavigate to a waypoint or along a route,choose GPS mode. The G-PILOT 3100steers the boat using navigation datafrom the GPS.For a sailing boatTo sail, tack and gybe at a set angleto the wind, choose wind mode. Windmode requires a wind instrument, such asNavman’s WIND 3100 to be connectedvia NavBus or NMEA.To steer to a set compass heading,choose compass mode.To use the G-PILOT 3100 with a GPS tonavigate to a waypoint or along a route,choose GPS mode.Note for sailing boatsThe G-PILOT is not recommended foruse in light, changeable or gusty winds.Take care when running to avoid an ac-cidental gybe.Wind mode requires the wind instrumentto be accurately calibrated.
