Your device must be connected to aNMEA 2000 or NMEA 0183 compatible wind sensor to performa wind hold or a wind-based tack or gybe.Setting the Wind Hold TypeBefore you can enable the wind hold type, you must connect aNMEA 2000 or NMEA 0183 wind sensor to the autopilot.For advanced autopilot configuration, see the installationinstructions included with your autopilot.1 From the autopilot screen, select Menu > Autopilot Setup >Wind Hold Type.2 Select Apparent or True.Engaging Wind HoldBefore you can enable the wind hold type, you must connect aNMEA 2000 or NMEA 0183 wind sensor to the autopilot.When the autopilot is in standby mode, select Wind Hold.Engaging Wind Hold from Heading HoldBefore you can enable the wind hold type, you must connect aNMEA 2000 or NMEA 0183 wind sensor to the autopilot.With heading hold engaged, select Menu > Wind Hold.Adjusting the Wind Hold Angle with the AutopilotYou can adjust the wind hold angle on the autopilot when windhold is engaged.• To adjust the wind hold angle in increments of 1°, select or.• To adjust the wind hold angle in increments of 10°, hold or.Tack and GybeYou can set the autopilot to perform a tack or gybe whileheading hold or wind hold is engaged.Tacking and Gybing from Heading Hold1 Engage heading hold (Engaging the Autopilot, page 37).2 Select Menu.3 Select an option.The autopilot steers your boat through a tack or gybe.Tacking and Gybing from Wind HoldBefore you can engage wind hold, you must have a wind sensorinstalled.1 Engage wind hold (Engaging Wind Hold, page 22).2 Select Menu.3 Select an option.The autopilot steers your boat through a tack or gybe, andinformation about the progress of the tack or gybe appearson the screen.Setting a Tack and Gybe DelayThe tack and gybe delay allows you to delay steering a tack andgybe after you initiate the maneuver.1 From the autopilot screen, select Menu > Autopilot Setup >Sailing Setup > Tack Delay.2 Select the length of the delay.3 If necessary, select Done.Enabling the Gybe InhibitorNOTE: The gybe inhibitor does not prevent you from manuallyperforming a gybe using the helm or step steering.The gybe inhibitor prevents the autopilot from performing agybe.1 From the autopilot screen, select Menu > Autopilot Setup >Sailing Setup > Gybe Inhibitor.2 Select Enabled.Adjusting the Autopilot ResponseWhen in sailboat mode, the Response setting allows you toadjust the rudder gain quickly to account for varying windconditions.1 From the autopilot screen, select Menu > Response.2 Adjust the rudder response.If you need the rudder to be more responsive and movequicker, increase the value. If the rudder is moving too much,decrease the value.Heading Line and Angle MarkersThe heading line is an extension drawn on the map from thebow of the boat in the direction of travel. Angle markers indicaterelative position from the heading or course over ground, whichare helpful for casting or finding reference points.Setting the Heading Line and Angle MarkersThe heading line is an extension drawn on the map from thebow of the boat in the direction of travel.
