1 Introduction The G-PILOT 3100 autopilot has three steering modes: Compass: The boat sails at a set compass heading. Wind: The boat sails and tacks at a set angle to the wind (requires a wind instrument, such as Navman’s WIND 3100 series, to be connected). GPS: The boat sails to a destination along a preset route (requires a GPS instrument, such as a Navman TRACKER chartplotter to be connected). The G-PILOT 3100 has three states: STBY (standby): The G-PILOT 3100 does not steer the boat.
2 Basic operation The display unit Display and keys are backlit (see section 3-1) Bar data (rudder or course error, see section 3-3) Main display always shows boat heading (see section 3-2) Steering mode (see section 2-4) Boat heading TRUE or MAG Operation (see section 2-5) Battery symbol flashes if battery low (see section 3-5) Simulate symbol (see section 3-6) Info display (see section 3-4) Alarm symbol flashes when alarm sounds (see section 3-5) Four keys (see section 2-2) 111 x 111 mm (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 profile suitable for the conditions (see section 7-2).
Setting the steering mode from the menu Go to STER MODE in the MAIN menu (see section 3-7) and select COM (compass), GPS or WIND. Setting the steering mode by shortcut key Hold MENU to go directly to the steering mode menu. far from the plotted course, the G-PILOT will display TRK ERROR (see section 5-2) To select Wind mode, the G-PILOT must be receiving data from a compatible wind instrument, otherwise the G-PILOT will display NO DATA.
2-6 Jog steer When the G-PILOT 3100 is in STBY (standby, see section 2-5) the helmsman must steer the boat manually. However the G-Pilot 3100 can turn the rudder; this is called jog steering: hold down < to turn the rudder to port hold down > to turn the rudder to starboard press and release < and > together to turn the rudder to amidships (this function is disabled until the rudder feedback unit and the compass have been calibrated (see the G- PILOT 3100 Installation Manual)).
3 Operation If the rudder is turned 30° or more, the display shows 30° and the arrowhead is on: 3-1 Set backlight for screen and keys To adjust the backlight, go to LAMP in the MAIN menu (see section 3-7). The options are OFF or 1 (least bright) to 4 (most bright). direction the rudder is moving. For example: 3-2 Heading display The main display always shows the boat Heading True or magnetic heading Rudder angle can be displayed even if the boat is being steered manually.
XTE, BRG, COG, DTG, TTG, SOG: GPS navigation data (see section 5-1); requires connection to a GPS instrument. WND: Wind angle (see section 6-1). To display APP (apparent) or TRUE wind angle, go to WIND TYPE in the VESSEL menu (see section 3-7). Requires connection to a wind instrument. BAT: G-PILOT 3100 power supply voltage. CUR: Steering drive current; the drive can be tested by checking the current during a jog (see section 2-6). OFF: nothing is displayed.

GYBE ANG The angle of course change in a gybe (40° to 140° or AUTO or OFF, default = AUTO) (see sections 4-5, 6.5). TACK DELY The delay between pressing tack and the boat starting to tack (1 to 120 sec or OFF; default = 30 sec) (see sections 4-5, 6-5). TURN RATE Set the maximum boat turn rate allowed, in degrees per sec (3 to 20, default = 10 degrees per sec).

4 Compass steering mode The G-PILOT 3100 has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode, see section 2-4. In Compass mode, the G-PILOT steers the boat to a set course, called CTS (Course to steer). 4-1 Compass steering data Boat heading, 45° Course error, 10° to starboard CTS (course to steer, the intended autopilot course) 55° 4-2 Engaging and disengaging the G-PILOT 3100 in compass mode Manually steer the boat to open waters.
When the G-PILOT 3100 is engaged Hold AUTO to attempt to switch to GPS mode (if vessel type is PLNE [planing] or DISP [displacement]) or to wind mode (if vessel type is SAIL).
4-4 Dodging in compass mode A dodge is a sharp change of course, usually to avoid an obstacle. press MENU + < to dodge to port by the dodge angle press MENU + > to dodge to starboard by the dodge angle. For example: Heading = 45° CTS = 45° Press ENT to continue on the new heading Press MENU + < or CTS changes by the dodge angle. Boat comes to new heading. The G-PILOT beeps. Press ESC to resume the earlier heading Note To dodge further, press MENU + < or MENU + > more times.
5 GPS steering mode The G-PILOT 3100 has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode, see section 2-4. In GPS mode, the G-PILOT uses data from a GPS to steer the boat along a route or to a waypoint.
5-2 Engaging and disengaging the G-PILOT 3100 in GPS mode Manually steer the boat to open waters. Start the GPS navigating to a waypoint, either a waypoint on a route or a single waypoint. BRG (direction of GPS course) Boat heading GPS plotted course to a waypoint XTE (distance to GPS course) To engage AUTO, hold AUTO To engage HAND STEER, hold AUTO + MENU AUTO: HANDSTEER: GPS plotted course The G-PILOT steers the boat automatically. Steer the boat manually.
When the G-PILOT 3100 is engaged Hold AUTO to change to Compass mode. Current: Wind or currents can push the boat off the GPS course. The G-PILOT 3100 will steer the boat back on course: If the GPS is following a route and the boat reaches an intermediate waypoint: If WPT AKN is off, the G-PILOT automatically starts steering to the next waypoint in the route. Otherwise, the G-PILOT displays NEXT WPT?, sounds an alarm and continues on the current heading. Press any key to mute the alarm.
6 Wind steering mode The G-PILOT 3100 has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode, see section 2-4. In wind mode, the G-PILOT steers the boat to a set angle to the wind, called SWA (set wind angle).
True and apparent wind speed and direction Apparent wind speed and direction are the values measured on the boat. True wind speed and direction are the values after allowing for boat speed through the air. If the boat is moving, then the apparent wind speed is different to the true wind speed and the apparent wind direction is different to the true wind direction, as shown below.
6-2 Engaging the G-PILOT 3100 in wind mode Manually steer the boat to open waters. Sail straight at the intended wind angle. The G-PILOT info data can display TRUE (true wind angle) or APP (apparent wind angle) (see section 3-4). For example: Wind APP = P40° Heading = 45° To engage AUTO, hold AUTO To engage HAND STEER, hold AUTO + MENU HANDSTEER: AUTO: Steer the boat manually. Display CTS in the info data or course error in the bar data and use these to steer by.
When the G-PILOT 3100 is engaged Hold AUTO to change to Compass mode. Wind or waves can push the boat so that the wind angle is different to SWA: Wind or currents can push the boat to one side of a straight course: If the wind direction changes, the boat's heading will change to keep the set wind angle the same.
6-4 Dodging in wind mode A dodge is a sharp change of course, usually to avoid an obstacle. press MENU + < to dodge to port by the dodge angle press MENU + > to dodge to starboard by the dodge angle. For example: Wind Press ESC to resume the earlier wind angle Press MENU + < SWA changes by the dodge angle. Boat comes to new wind angle. SWA = 40° The G-PILOT beeps. Note To dodge further, press MENU + < or MENU + > more times.
Example: SWA is 120°, so the boat will gybe. The tack angle is not set to AUTO: Example: SWA is 40°. The tack angle is set to AUTO so the boat changes direction once: Wind End of tack, boat is at new SWA Press AUTO + > to initiate a gybe to starboard The G-PILOT 3100 counts down the tack delay.
7 Optimizing steering performance 7-1 The steering parameters The G-PILOT 3100 has six steering parameters which can be adjusted to optimize steering performance: Response How far the boat can move off course before the G-PILOT 3100 turns the rudder to correct the course. A lower response setting means the boat can move further off course before the G-PILOT 3100 corrects. To change, go to RESPONSE in the MAIN menu (see section 3-7). The range is 1 to 10, A1 to A5.
To simplify changing the parameters when conditions change, the G-PILOT stores five sets of the steering parameters. Each set is called a profile and the profiles are numbered 1 to 5. To select a profile to use, go to PROFILE in the MAIN menu (see section 3-7). 1 2 3 4 When the G-PILOT is installed, the steering parameters in all the profiles are set to their default values. Select profile 1 and adjust the steering parameters for optimum steering in typical conditions (see section 7-3).
Problem: after a large course change, boat takes too long to settle to new course Decrease counter rudder gain Problem: after a sideways current or wind, the correction is applied too quickly or too slowly If the boat encounters a sideways force, then it will move off course sideways. The G-PILOT will automatically bring the boat back to the correct heading by applying a few degrees of rudder, called trim. Trim gain sets how quickly the trim is applied.
