My Vessel Layer Settings
From a chart, select Menu > Layers > My Vessel.
Heading Line: Shows and adjusts the heading line, which is a line drawn on the map from the bow of the boat in
the direction of travel (Setting the Heading Line and Angle Markers, page16).
Laylines: Adjusts the laylines, when in sailing mode (Laylines Settings, page24).
Roses: Allows you to display roses on the chart. Wind roses show a visual representation of the wind angle
or direction provided by the connected wind sensor. The compass rose indicates the compass direction
oriented to the heading of the boat.
Vessel Icon: Sets the icon that represents your present location on the chart.
Laylines Settings
To use the laylines features, you must connect a wind sensor to the chartplotter.
When in sailing mode (Setting the Vessel Type, page8), you can display laylines on the navigation chart. Laylines
can be very helpful when racing.
From the Navigation chart, select Menu > Layers > My Vessel > Laylines.
Mark: Sets how the laylines appear on the chart.
Vessel: Sets how the vessel appears on the chart.
Length: Sets the length of the laylines.
Display: Sets how the laylines and vessel appear on the chart.
Setup > Sailing Angle: 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.
Setup > Windward Angle: Allows you to set a layline based on the windward sailing angle.
Setup > Leeward Angle: Allows you to set a layline based on the leeward sailing angle.
Setup > Tide Correction: Corrects the laylines based on the tide.
Setup > Filter Time Constant: 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.
