Laylines Settings
To use the laylines features, you must connect a wind sensor to the
AQUAMAP.
When in sailing mode, you can display laylines on the Nav. chart. Laylines
can be very helpful when racing.
From the Nav. chart, select
MENU

Laylines
.
Display
: Sets how the laylines and vessel appear on the chart, and sets the
length of the laylines.
Sailing Ang.
: Allows you to select how the device calculates laylines. The
Actual option calculates the laylines using the measured wind angle from
the wind sensor. The Manual option calculates the laylines using manually
entered windward and leeward angles.
Windward Ang.
: Allows you to set a layline based on the windward sailing
angle.
Leeward Ang.
: Allows you to set a layline based on the leeward sailing
angle.
Tide Correction
: Corrects the laylines based on the tide.
Layline Filter
: Filters the layline data based on the time interval entered.
For a smoother layline that filters out some of the changes in the boat’s
heading or true wind angle, enter a higher number. For laylines that
display a higher sensitivity to changes in the boat’s heading or true wind
angle, enter a lower number.
Setting the Keel Offset
You can enter a keel offset to compensate the water depth reading for the
transducer installation location. This allows you to view the depth of the water
below the keel or the true depth of the water, depending on your needs.
NOTE:
This option is only available when you have valid depth data.
1
Measure the distance:
• If the transducer is installed at the water line
1
or anywhere above the
end of the keel, measure the distance from the transducer location to
the keel of the boat. Enter this value as a positive number.
• If the transducer is installed at the bottom of the keel
2
and you want
to know the true depth of the water, measure the distance from the
transducer to the water line. Enter this value in as a negative number.
