Congratulations on choosing the Navman G-PILOT 3380 G-PILOT. For maximum benefit, please read this manual carefully before installation and use. This manual describes how to use and set up the G-PILOT 3380 and the associated equipment. This manual also explains how to operate the G-PILOT 3380 effectively and provides troubleshooting and performance tips.
1 Introduction The G-PILOT 3380 is a superior quality, high performance G-PILOT display head. The Navman G-PILOT system has the flexibility to be used with power or sail boats. The G-PILOT 3380 has dedicated function keys and a large 3.8” Color TFT display. This provides the user with exceptionally easy to use controls. The G-PILOT 3380 is part of the Navman family of instruments for boats, which includes instruments for speed, depth, wind and repeaters.
1-1-3 Power steering modes 1-1-4 Turn modes When the G-PILOT is in STBY (STANDBY) mode the helmsman must steer the boat manually. However The G-PILOT 3380 has two different power steering control modes (see section 3-11). The G-PILOT 3380 can follow a preprogrammed turn sequence. The G-PILOT has three different turn modes (see section 3-10): Jog: Turns the rudder left or right while the key is pressed. Tack/Gybe: Auto-tacks OR Auto-gybes the boat after a delay period.
2 Quickstart 2-1 2-4 Starting the G-PILOT system 1. Turn the G-PILOT system on by pressing . 2. If the G-PILOT is connected to speed, wind or GPS instruments, turn these on too.

6-7 Setup > Comms Rudder Use this calibration wizard to calibrate the rudder. Use this feature when the G-PILOT is connected to other Navman instruments through NavBus or any compatible NMEA instrument. Follow the on-screen instructions: NMEA mode Select NMEA port mode.
7 Steering modes 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.
7-1-2 Engaging and disengaging the G-PILOT in compass mode For example: Manually steer the boat to open waters. Sail straight on the intended course. Heading = 45° To engage AUTO, press To engage H STEER, hold AUTO: 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.
7-2 GPS steering mode The G-PILOT has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode, see section 3-7. In GPS mode, the G-PILOT uses data from a GPS to steer the boat along a route or to a waypoint.
7-2-2 Engaging and disengaging the G-PILOT 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. GPS plotted course to a waypoint BRG (direction of GPS course) XTE (distance to GPS course) To engage AUTO, press To engage HAND STEER, hold HANDSTEER: AUTO: 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.
7-2-3 Arriving at waypoints If the GPS is following a route and the boat reaches an intermediate waypoint: If the Waypoint Acknowledge alarm (see section 6-5) is off, the G-PILOT automatically starts steering to the next waypoint in the route. If the Waypoint Acknowledge alarm is on, the G-PILOT shows the following alarm: The G-PILOT continues steering on the old course. Select “OK” to start steering to the next waypoint.
7-3 Wind steering mode The G-PILOT has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode, see section 3-7. In wind mode, the G-PILOT steers the boat to a set angle to the wind, called SWA (set wind angle). 7-3-1 Wind steering data Course error CTS (intended G-PILOT course, to achieve the SWA [set wind angle]) Boat heading SWA (set wind angle), 41° Wind angle can be APP (apparent) or TRUE Wind APP Apparent wind angle The apparent wind angle at the boat.
7-3-2 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.
7-3-3 Engaging the G-PILOT in wind mode Manually steer the boat to open waters. Sail straight at the intended wind angle. For example: Wind APP = P40° The G-PILOT 3380 info data can display TRUE (true wind angle) or APP (apparent wind angle) (see section 3-4) SWA = 45° To engage AUTO, press To engage HAND STEER, hold HANDSTEER: AUTO: GPS plotted course The G-PILOT steers the boat automatically. Steer the boat manually.
7-3-4 Wind gain In GPS mode, The wind gain determines how much correction is applied to reduce any difference between the set wind angle and the actual wind angle. A high setting will cause the G-PILOT to be strongly affected by changes in the wind. A low setting will cause the G-PILOT to be very mildly affected by changes in the wind.
8 Optimising steering performance 8-1 Steering parameters The G-PILOT has seven steering parameters which can be adjusted to optimize steering performance. Select the Advanced checkbox to view all parameters. These parameters can be adjusted using the Parameters menu. To adjust the parameters, go to Menu > Setup > Profiles > Parameters (see section 6-2). From the Basic, G-PILOT or Compass screens, press to open the Parameters menu directly.
• • For higher boat speeds and large GPS routes, decrease GPS gain; for lower speeds and tight GPS routes, increase GPS gain. For higher and/or more stable winds, increase wind gain; for lower and/or unstable winds, decrease wind gain. 3. If the conditions change and the steering is no longer optimum, select another profile and adjust the steering parameters again Repeat this step as required to adjust the parameters in each profile.
8-3 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. Increase trim gain. or 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: 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.
9 Troubleshooting This troubleshooting guide assumes that you have read and understood this manual. 4 When sailing a straight course, the boat drifts off course: It is possible in many cases to solve difficulties without having to send the unit back to the manufacturer for repair. Please follow this troubleshooting section before contacting the nearest Navman dealer. a Change to a profile suitable for boat speed and sea conditions (see section 8-2).
