During the Race
Sailing upwind
Tack when headed to keep the boat sailing on the lifted tack.
The bar graph indicates the Wind Shift in 2.5 degree steps from a central
zero. Bar Graph above the centre line indicates a lift, Bar Graph below
the centre line indicates a header.
When the Wind Shift (WND) page is selected, Wind Shift is shown as a
+ (lifted) or – (headed) value in the lower pane.
Oscillating wind pattern
If the wind is swinging regularly either side of the Mean Wind
Direction (MWD), you should tack on headers to keep sailing
on the lifted tack, i.e. you should tack on “-” digital or bar graph
indications.
Permanent wind shifts
These can be recognised as a constant header on one tack, and a
constant lift on the other tack. In this situation, you can adjust the
Mean Wind Direction (MWD) as follows:
1 Sail close hauled on either tack.
2 If on starboard tack, press
. If on port tack, press
. The
new Mean Wind Direction (MWD) is captured.
3 The Mean Wind Direction (MWD) pop-up is displayed.
4 If required, the value can be adjusted using
and
.
Sailing Downwind
Gybe to keep the bar graph low, to sail on the headed tack.
The bar graph displays Downwind Angle (the angle of the boat
from the mean downwind direction) in 2.5 degree steps from
0 to 50 degrees, from zero at the bottom of the display. For
example, at 45 degrees the bar graph is almost full length and the boat
is sailing at 45 degrees from the mean downwind direction.
When the Wind Shift (WND) page is selected, Downwind Angle is shown
on the numeric display and the direction is shown by (Port) or (Stbd),
e.g. the example shows that the boat is sailing 20 degrees to starboard
of the mean down wind direction.
