Laylines Settings
To use the laylines features, you must connect a wind sensor to the chartplotter.
When in sailing mode (Setting the Vessel Type for Sailing Features, page50), you can display laylines on the
navigation chart. Laylines can be very helpful when racing.
From the Navigation chart, select > Layers > My Vessel > Laylines > Setup.
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. The Polar Table option calculates the laylines based on the
imported polar table data (Importing a Polar Table Manually, page52).
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.
