Suunto M9 Quick Manual page 29

Set the TAD measurement for the starboard tack:
1. Press ENTER to store the tack heading.
2. Select STB Tack from the menu list.
3. Press ENTER to confirm the setting.
Race Course and Buoys:
The race courses in the Suunto M9 can contain the same
waypoints (turn buoys) multiple times. Updating the buoy
location once also updates the same buoys in the list.
This way, you can store different race course templates
containing approximate buoy locations (when the actual
bouy locations are not known). As you sail around the
buoys and store their locations, the unit updates the
laylines and other sailing data to refer to the specific buoy.
At the turn buoys:
1. Press ENTER to store the location.
2. Select the correct turn buoy from the menu list.
3. Press ENTER to confirm the buoy location.
Laylines:
When the tack angles and the
actual buoy locations have been
stored, the Suunto M9 displays
the time and distance left to
layline based on the current speed
and heading. Suunto M9 uses the
latest tacking angles to calculate
the layline location.
Race Restart:
In case the race
is restarted or
another race is
conducted on
the same
course, select
Restart.
The Suunto M9
asks you to
reset the timer
for the new start
but it keeps the
wind and the
start line
information
active.
