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.

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.
