The Tack function will also work when gybing.

To make larger course changes press the AUTO key to disengage Auto mode, turn the vessel manually, then
press the AUTO key to engage Auto mode again to continue on your new heading and a new wind angle.

Navigator course control

The Pilot can be interfaced to a navigation device such as a GPS, Loran or Plotter using the Industry
Standard NMEA 0183 format. Once a waypoint has been selected as a target and the navigation device is
providing the Pilot with navigation data to the target, the Pilot may be engaged under Navigator course con-
trol.
Steer the boat onto the desired heading to minimise any Cross Track Error, so that Auto mode can be enga-
ged.
As soon as Navigator course control is selected the Pilot will read the magnetic bearing to the target from
the navigator (if magnetic bearings are not available, the Pilot Computer will automatically use true bearings)
and use this as the course to steer. Selecting Auto mode will then cause the Pilot to turn the vessel onto that
course and hold it.
The Pilot constantly monitors the Cross Track Error signal from the navigator and applies Navigator Gain to
maintain a direct Course Over Ground to the target.
Note that the vessel may establish a "crab" angle to compensate for wind and tide as it steers to the way-
point.
If a new waypoint is selected in the navigator, manually or because it is in a route, the Pilot will be triggered,
by a change of waypoint identifier, to accept a new course to steer.
The Pilot will then automatically turn to the new course, or wait until the AUTO key is pressed before it turns,
depending whether the automatic or manual option has been set. While under Navigator Control, both the
