1 Introduction

The WIND 3100 displays: Apparent wind direction and wind speed. True wind direction and wind speed (requires data from a speed instrument). Maximum wind speed. Steering directions to sail at a constant angle to the wind (steer to wind). VMG, the component of boat speed parallel to the wind (requires data from a speed instrument). An installed WIND 3100 has two parts: The display unit. The masthead unit, which has devices for measuring wind speed and wind direction. The unit is powered from the boats power supply. The WIND 3100 is part of the NAVMAN family of instruments, which includes instruments for speed, depth, wind and repeaters. These instruments can be connected together to form an integrated data system (see section 6). For maximum benefit, please read this manual carefully before installation and use.

How it measures wind speed
The masthead unit has a rotor with three windcups which spins as the wind moves past the boat. The masthead unit measures how fast the rotor is spinning to calculate the wind speed.
How it measures wind direction
The masthead unit has a windvane which points in the direction that the wind is coming from. The masthead unit electronically senses the direction the windvane is pointing.

Cleaning and maintenance

Clean the display unit with a damp cloth or mild detergent. Avoid abrasive cleaners, petrol or other solvents.

3 Wind direction

3-1 Wind direction display
To display wind direction, press one or more times, until TRUE (true wind direction) or APP (apparent wind direction) is displayed. True wind direction is only displayed if the WIND 3100 is connected to a speed instrument. The wind direction is displayed in degrees (0 to 180 port or starboard) and by the pointer (see right). Wind from 30 to starboard, pointer type 1 Wind direction
3-2 Set wind direction pointer type
The wind direction pointer can be set to one of five types (see right). Type 1 is the default. Types 1, 2 and 3 simulate wind vanes, and have a black spot in the centre. The thinner part points to where the wind is coming from. Types 4 and 5 point to where the wind is coming from. To set the pointer type: 1 Press + several times until the Pointer Type screen is displayed: Wind from 30 to port, pointer type 2 Wind direction

Press Press

to set the pointer type. Wind direction Wind from 30 to starboard, pointer type 4 Wind direction
3-3 Set wind direction damping
Wind turbulence, gusts and mast motion cause the wind direction to fluctuate. To give a stable reading, the WIND 3100 calculates the wind direction by measuring the direction several times and averaging the measurements. The wind direction damping value ranges from 1 to 5: A lower value averages readings over a shorter period of time. This gives the most accurate direction but has the most fluctuations. A higher value averages readings over a longer period of time. This gives the most stable direction but will ignore some true changes in direction. Note : The damping affects the numeric wind direction, not the pointer. Set the wind direction damping to the lowest value which gives a stable numeric wind direction. Values of 1, 2, 3, 4 and 5 average readings over a time period of 6, 12, 18, 24 and 30 seconds respectively. To set the damping:

To start steering to wind, press displayed. The display shows: 1 until STEER is The top two segments are always on The greater the steering error, the more segments turn on The steering resolution determines how many segments turn on. The number of segments that turn on is the steering error divided by the steering resolution (to set the steering resolution, see section 5-2). If the boat should steer to port, then segments to the right of centre turn on If the boat should steer to starboard, then segments to the left of centre turn on.
The required steering angle to the apparent wind (to set the required steering angle, see section 5-1). A direction arrow showing which way to steer to reach the required steering angle. The steering error (the difference between the required steering angle and the actual steering angle) is shown on the circular display:
Steer to wind examples The required steering angle is 40 and the boat is at 30 to the apparent wind. The steering error is 10. The boat should turn 10 to port.

6 Systems of several instruments
Several NAVMAN instruments can be connected together to share data. There are two ways of connecting instruments together, NavBus or NMEA. corresponding external data is not available then the displayed value will be dashes ( ). To display true wind speed, true wind direction and VMG, the WIND 3100 must be connected to an instrument that outputs boat speed. Typical instruments that output boat speed are: A GPS receiver (outputs boat speed over ground). A NAVMAN SPEED 3100, which uses a paddlewheel transducer (outputs boat speed through water). Note: If there is a current, these two speeds are different. You must select which type of boat speed the WIND 3100 will use (see section 3.1 and 8-2, step 2).

6-1 NavBus

NavBus is a NAVMAN proprietary system that allows systems of multiple instruments to be built using a single set of transducers. When instruments are connected by NavBus: If you change the units, alarms or calibration in one instrument, then the values will automatically change in all other instruments of the same type. Each instrument can be assigned to a group of instruments (see section 1, 8-2, step 3). If you change the backlight in an instrument in group 1, 2, 3 or 4 then the backlight will automatically change in the other instruments in the same group. If you change the backlight in an instrument in group 0 then no other instruments are affected. If an alarm sounds, mute it by pressing instrument which can display that alarm. on any

6-2 NMEA

NMEA is an industry standard, but is not as flexible as NavBus as it requires dedicated connections between instruments. Wind, speed and direction data are output by the WIND 3100 and can be read and displayed by the NAVMAN REPEAT 3100 or other NMEA instruments. The WIND 3100 can receive NMEA boat speed data: RMC or VTG from any compatible GPS instrument (speed over ground) VHW from any compatible instrument with a paddlewheel speed transducer (speed through water). You must select which type of boat speed the WIND 3100 will use (see section 3-1, 8-2, step 2).
NavBus and the WIND 3100 If the WIND 3100 does not have a masthead unit fitted then the unit will automatically take wind direction and speed readings from another instrument, via NavBus, if the data is available. For more information, refer to the NavBus Installation and Operation manual. If a masthead unit is not fitted to the unit and the

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 Navmans 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. Steer the boat with the manual helm. AUTO: The G-PILOT 3100 steers the boat automatically. HAND STEER: The G-PILOT 3100 displays steering information for the helmsman to use to steer a course manually. The unit is powered from the boats power supply. The G-PILOT 3100 is part of the Navman family of instruments for boats, which includes instruments for speed, depth, wind and repeaters. These instruments can be connected together to form an integrated data system for a boat. The G-PILOT 3100s performance is enhanced if it is connected to a boat speed instrument such as Navmans SPEED 3100 or a GPS.

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. Steering mode is shown on the display
2-5 STBY (standby), AUTO and HAND STEER
The G-PILOT 3100 can operate in STBY (standby), AUTO or HAND STEER:

Power on

Hold AUTO + MENU Press AUTO AUTO Autopilot steers the boat. Autopilot displays heading and navigation data. Do not steer the boat manually. HAND STEER Autopilot does not steer the boat. Autopilot displays heading and navigation data. Steer manually using the displayed navigation data. CTS (course to steer) can be displayed in the info display (see section 3-4). Course error can be displayed in the bar data (see section 3-3).
STBY (standby) Autopilot does not steer the boat except during jog steer. Autopilot displays heading but does not display steering data. Steer the boat manually.

Hold AUTO Press AUTO

For information on jog steer, see section 2-6. For information on engaging and using the G-PILOT 3100 for AUTO and HAND STEER: For Compass mode: see section 4. For GPS mode: see section 5. For Wind mode: see section 6.

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)). For example: Rudder is amidships Hold <, the rudder turns to port and the boat turns to port Release <, the rudder stays to port Boat keeps turning to port

Rudder is to port

Hold >, the rudder turns to starboard Release >, the rudder stops, but is still to port
Boat keeps turning to port

Press and release

Boat goes straight

< + > together

the rudder turns to amidships. To stop the rudder turning to amidships press ESC, < or >
Warning Until the rudder feedback unit is calibrated, there is no rudder limit and the user must ensure that the rudder is not driven onto an endstop when using jog steering. Note Normally during a jog the info data (see section 3-4) displays JOG. However, if CUR (drive current) is selected then this current is displayed during a jog as an aid for testing the steering drive.

3 Operation

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). If the rudder is turned 30 or more, the display shows 30 and the arrowhead is on:

3-2 Heading display

The main display always shows the boat Heading True or magnetic heading
direction the rudder is moving. For example: Rudder angle can be displayed even if the boat is being steered manually. Course error The course error is the angle between the actual boat heading and the intended autopilot course, for example: Actual heading 90 CTS (course to steer) 110
heading: To display MAG (magnetic) or TRUE headings, go to HDG TYPE in the OPTIONS menu (see section 3-7).
Course error is 20 to starboard
Actual heading 290 CTS 250 Course error is 40 to port, but 30 is the largest error that can be displayed, so the display shows 30 to port

3-3 Bar data display

The bar data at the top of the display can display rudder angle or course error. To select what is displayed, go to BAR DATA in the MAIN menu (see section 3-7). The options are RUD (rudder angle) or CE (course error). If the G-PILOT 3100 system has more than one display unit, then the bar data display can be selected differently in each display unit. Rudder angle Rudder angle is the angle that the rudder is turned from amidships. When the G-PILOT 3100 is driving the rudder, an arrowhead at the end of the bar data turns on, pointing in the G-PILOT is not driving rudder, rudder is amidships
In STBY (standby), course error displays as zero.

3-4 Info data display

The info data is at the bottom of the screen, and can display one item of steering or navigation data. To select what data is displayed, go to INFO DATA in the MAIN menu (see section 3-7). If the G-PILOT 3100 system has more than one display unit, then the info data display can be selected differently in each display unit. The options are: CTS: The course the G-PILOT 3100 intends the boat to steer; in STBY (standby) there is no CTS and the display shows CTS .

3-6 Simulate mode

Simulate mode allows you to become familiar with the unit off the water. The word SIMULATE ashes on the display. To turn Simulate mode on or off: Turn the unit off (see section 2-1). Hold down AUTO while you turn the unit on (see section 2-1).

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. Sail straight on the intended course. For example:
Heading = 45 To engage AUTO, hold AUTO AUTO: To engage HAND STEER, hold AUTO + MENU HANDSTEER:
The G-PILOT steers the boat automatically.
Steer the boat manually. Display CTS in the info data or course error in the bar data and use these to steer by. Heading = 45 CTS = 45
The G-PILOT 3100 sets CTS (course to steer) to the current heading, in this example 45, and starts steering on this course.
To disengage the G-PILOT, press AUTO The G-PILOT returns to STBY (standby). Steer the boat manually.
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). Waves or wind can push the boats heading off course, The G-PILOT 3100 will steer the boat back on course, for example: CTS = 45 Wave pushes boat heading to 60 Wind or currents can push the boat to one side of the course, for example:

CTS = 45 Current

G-PILOT 3100 steers boat back to a heading of 45
Heading is maintained at 45
4-3 Changing course in compass mode
To change course in 1 steps: press < to change course by 1 to port press > to change course by 1 to starboard. For example: Heading = 45 CTS = 45 Press < Heading = 45 CTS = 45 Press >
CTS changes to 44 Boat comes to 44 heading
CTS changes to 46 Boat comes to 46 heading
To change course in 10 steps: hold down < to change course by 10 to port every half second hold down > to change course by 10 to starboard every half second. For example: Heading = 45 CTS = 45 Hold < for half a second Hold < until CTS is 15
CTS changes to 35 Boat comes to 35 heading

5-1 GPS navigation data

Example of navigating to a waypoint:
Destination DTG (distance) SOG (speed) COG (bearing) TTG (time)
BRG (bearing) CTS (bearing) Course error (angle) Plotted course XTE (distance) Start The boat is sailing from the start to the destination and has moved off the GPS plotted course from the start to the destination: BRG Bearing to destination Course error CTS DTG SOG Course to steer Distance to go Speed over ground The bearing to the destination from the boat. The difference between CTS and the boat heading. Optimum course to steer to return to the plotted course. Distance from the boat to the destination. The current boat speed over the ground. This is not necessarily the same as the boat speed through the water nor the speed at which the boat is approaching the destination. The estimated time to reach the destination. The distance from the boat to the nearest point of the plotted course. XTE may have a letter: R means steer to the right to return to the plotted course, L means steer to the left. Boat

TTG XTE

Time to go Cross track error
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 AUTO:
To engage HAND STEER, hold AUTO + MENU HANDSTEER: GPS plotted course
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 is engaged, if the XTE is more than 0.05 nm or the boat heading is not within 30 of BRG then the G-PILOT displays TRK ERROR. Press ESC to return to Compass mode or press ENT to have the G-PILOT steer the boat to the course. When the G-PILOT is engaged, it uses data from the GPS to steer the boat along the plotted course to the waypoint. To disengage the G-PILOT, press AUTO The G-PILOT returns to STBY (standby). 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. Then press ENT to start steering to the next waypoint or press ESC to return to STBY. When the boat reaches the nal waypoint, the G-PILOT displays ROUTE END and stays on the current course: Press ESC to change to STBY; steer manually Press ENT to change to Compass mode and continue sailing at the current heading. Note To return to the last waypoint if the boat has passed the waypoint, restart the GPS navigating to the waypoint.

To view or change WPT AKN, go to WPT AKN in the ALARMS menu (see section 3-7).

5-3 Dodging in GPS 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:
CTS changes by the dodge angle. Boat comes to new heading. The G-PILOT beeps. WARNING: The G-PILOT will steer back to the GPS plotted course. Make sure there are no obstacles or dangerous waters in the way. Note To dodge further, press MENU + < or MENU + > more times. To view or change the dodge angle, go to DODGE ANG in the OPTIONS menu (see section 3-7).

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).

6-1 Wind steering data

Boat heading Course error, 10 to starboard CTS (intended autopilot course, to achieve the SWA [set wind angle]) SWA (set wind angle), 45
Wind angle, can be APP (apparent) or TRUE APP CTS
Apparent wind angle The apparent wind angle at the boat. P in front of the angle means the wind is from port, S means that the wind is from starboard. Course to steer Course error The course to steer to maintain the SWA (set wind angle). The difference between APP (wind angle) and SWA (set wind angle). The desired wind angle. The true wind angle at the boat. P in front of the angle means the wind is from port, S means that the wind is from starboard.

Set wind angle

TRUE True 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. Boat at rest True wind speed is the same as apparent wind speed and true wind direction is the same as apparent wind direction

Boat is at rest

Boat moving upwind Apparent wind speed is greater than true wind speed and apparent wind direction is closer to dead ahead than true wind direction Apparent wind speed 28 kts
True wind direction 45 Boat speed 10 kts

True wind speed 20 kts

Apparent wind speed 28 kts
Apparent wind direction 30

Boat speed 10 kts

Boat moving downwind Apparent wind speed is less than true wind speed and apparent wind direction is closer to dead ahead than true wind direction True wind speed 20 kts Apparent wind speed 15 kts True wind direction 135

Apparent wind speed 15 kts
Apparent wind direction 107
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
Steer the boat manually. Display CTS in the info data or course error in the bar data and use these to steer by. Wind APP = P40 The G-PILOT 3100 sets CTS (course to steer) to the current The G-PILOT steers the boat automatically. heading, in this example 45, sets SWA (set wind angle) to the current wind angle and starts steering at this wind angle. SWA = 40
To disengage the G-PILOT, press AUTO The G-PILOT returns to STBY (standby). Steer the boat manually. The G-PILOT 3100 can also be engaged on the starboard tack, for example: Wind
or when running, for example: Wind
APP = S120 APP = S40 SWA = 40

SWA = 120

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 Wind or currents can push the boat to one side of a straight course: Wind If the wind direction changes, the boat's heading will change to keep the set wind angle the same. Wind New wind direction Wave Current
New heading The G-PILOT will steer the boat back to the SWA The G-PILOT will steer the boat at the set SWA The wind alarm can be set to sound if the wind direction changes too far, go to WND ALARM in the ALARMS menu (see section 3-7).
6-3 Changing SWA (set wind angle) in wind mode
To change SWA in 1 steps: press < to change SWA by 1 to port press > to change SWA by 1 to starboard. For example, on a port tack: Wind Wind or, on a starboard tack:

Press <

SWA = 40 SWA changes to 39. Boat comes to new wind angle of 39 To change SWA in 10 steps:

SWA = 40

SWA changes to 41. Boat comes to new wind angle of 41
hold down < to change SWA by 10 to port every half second hold down > to change SWA by 10 to starboard every half second for example: Wind Hold < for half a second Hold < until SWA is 120
SWA changes to 50. Boat comes to new wind angle of 50
Boat comes to new wind angle of 120

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: Press MENU + < SWA changes by the dodge angle. Boat comes to new wind angle. SWA = 40 The G-PILOT beeps. Press ESC to resume the earlier wind angle

To simplify changing the parameters when conditions change, the G-PILOT stores ve sets of the steering parameters. Each set is called a prole and the proles are numbered 1 to 5. To select a prole to use, go to PROFILE in the MAIN menu (see section 3-7). When the G-PILOT is installed, the steering parameters in all the proles are set to their default values. Select prole 1 and adjust the steering parameters for optimum steering in typical conditions (see section 7-3). If the conditions change and the steering is no longer optimum, select another prole and adjust the steering parameters again. Repeat this step as required to adjust the parameters in each prole. When using the G-PILOT to steer, select a prole suitable for the current conditions. For example different proles can be congured for rough conditions and calm conditions.
7-3 Adjusting the steering parameters
Problem: rudder turns too frequently
This causes wear on the steering linkage and uses power. Decrease response. Reduce ratio. Reduce counter rudder gain.
Problem: drifts off course to one side
Increase ratio. or Increase trim gain. Increase response.
Problem: boat moves too far off course closely before the rudder turns to correct the course
Decrease ratio. Decrease counter rudder gain. Decrease trim gain.
Problem: oscillations from side to side build up

Decrease ratio.

Problem: after a large course change, boat overshoots and oscillates before settling to new course
Increase counter rudder gain
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. Trim gain should be adjusted to trim the boat in about one minute. Getting the Trim gain setting right can be difcult for your specic boat and it is easy to alter the Trim gain too much. Change the settings slowly and conservatively at rst, until the right settings are known. a Boat takes much more than one minute to trim Sideways force starts Increase trim gain
1 minute b Boat takes much less than one minute to trim Sideways force starts Decrease trim gain
1 minute Problem: drifts off GPS course

Increase GPS gain.

Problem: boat oscillated around GPS course

Decrease GPS gain.
