2.13 Tacking in Auto mode
The tack function is only available in sailboats when the system
is set up for SAIL boat type in the installation setup.
Tacking in AUTO mode is different from tacking in WIND
mode. In AUTO mode the tack angle is fixed and can be set in
the Installation/Dockside menu.
Tacking should only be performed into the wind and must be
tried out in calm sea conditions with light wind to find out how it
works on your boat. Due to a wide range of boat characteristics
(from cruising to racing boats) the performance of the tack
function may vary from boat to boat. Except for the fixed course
change and the difference in displays, the procedure is similar to
that of the U-Turn described on page 25.

2.14 Navigating with the AP26 and AP27
The autopilot has the capability to use steering information from
an external navigator (GPS, Chart Plotter) to direct the boat to a
specific waypoint location, or through a route of waypoints. In
the NAV mode, the autopilot uses the compass as heading source
for course keeping. The information received from the navigator
alters the set course to keep the boat on the track line and direct
the autopilot to the destination waypoint.
Note ! Navigational steering should only be used in open waters. By
selecting the NAV mode, the autopilot is set for automatic
steering on the current set course and then waits for the user to
accept the course change to the track line or destination
waypoint.
To obtain satisfactory navigation steering, the following points
must be fulfilled prior to entering the NAV mode:
