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.
