Ship & Tracks

The Ship & Track options are used to configure the vessel's COG & SOG predictor line and various track recording and display options.

  • Own Ship Trail Length: Adjusts the length of the trail (in time) displayed on the chart. Make sure to review the Trail & Tracks chapter for more information.

  • Trail Thickness: Adjusts the thickness of the trail.

  • Own Ship COG/SOG Predictor: Selects if the Course Over Ground (COG) predictor varies in length according to speed or fixed by a distance value.

  • COG/SOG Predictor Length: Adjusts the Course Over Ground (COG) predictor length when set for distance.

  • COG/SOG Predictor Time: Increases the time value to make the Course Over Ground (COG) & Speed Over Ground (SOG) predictor line longer. Decreases the time value to make the predictor lines smaller.

Note: The COG/SOG Predictor Time setting also affects the ARPA and AIS target predictor. The SOG Predictor Time value is also used for the Drift vector (same setting).

  • COG/SOG Predictor Thickness: Adjusts the thickness of the Course Over Ground (COG) predictor line.

  • Heading Line Color: Adjusts the color of the Heading Line.

  • Heading Line Thickness: Adjusts the thickness of the Heading Line.

  • Autoshift Maximum Speed: When the Autoshift mode is selected (look ahead), this value is used to determine the off center position of the boat based on its speed. For example, if this value is set to 10Kn, the boat will be off centered to the edge of the motion circle at speed of 10kn and above.

  • Motion Circle: Increases or decreases the size of the Relative Motion Circle (used for Relative and True Motion). Refer to the Centering on the boat chapter for more information on the Relative Motion Circle.

  • Range Circle Size: Adjusts the range circle size (that can be displayed around the boat icon by enabling it by right clicking on the boat icon).

  • Range Circle Color: Adjusts the range circle color

  • Range Circle Thickness: Adjusts the range circle thickness

  • Track Thickness: Increases or decreases the thickness of all the track lines that are set to use the "Default" thickness. Track thickness can be customize independently for each track by right clicking on the track and selecting a thickness size other than the "default" size.

  • Track Color: Changes the default Track line color to one of 8 fixed set colors.

  • Delete ALL Tracks: Push this button to delete all Tracks that you have created to date.
