Simrad AP21 and AP22 Autopilots

2.15 TURN-mode
The autopilot provides a special U-turn feature when in AUTO
mode. This feature is very useful in a man overboard situation.
U-Turn changes the current set course to be 180 degrees in the
opposite direction. The user may decide if the U-Turn should be
made to Port or Starboard to bring the boat on the new course. U-
Turn is activated by a quick double press on the DODGE button.
The autopilot will continue on the set course until you press
either the PORT or STBD button to select the direction to make
the U-Turn. If you do not press PORT or STBD within 1 minute,
the autopilot will return to the AUTO mode and stay on course.

2.16 Tacking in Auto mode
When the autopilot is installed on a sailboat, a fixed tack of 100
degrees can be made in AUTO mode.
The use of this function should be carefully considered based on
the boat's characteristics and the weather conditions. The tack
function should only be used into the wind and must be tried out
in good weather conditions with light wind to find out how it
works on your boat. Due to wide range in boat characteristics
(from cruising to racing boats) the performance of the tack
function may vary from boat to boat. Except for the course
change of 100° the procedure is similar to that of the U-Turn
described above.
