2.14 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. Default tack angle is 100°.
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
24.

2.15 NoDrift
Note ! The source when operating in NoDrift mode is the Position (Pos)
source.
The NoDrift mode is an alternative to route steering in NAV
mode, and is automatically entered when you press the
NAV WIND button provided NoDrift has been selected in the
(user) SETUP menu.
The autopilot will steer to an imaginary waypoint and the
bearing is the boat’s heading at the very moment the NoDrift
mode is engaged.
Unlike when in Auto mode the vessel will steer a course equal to
the bearing line unaffected by wind and current (no drift).
The course to steer to (bearing line) can be changed the same
way as when changing course in Auto mode.
