Laylines
Layline target type is selected via layline options in the chart settings, Target Wind Angle.
Choose between, Actual wind angle. Manual set wind angle or Polar target wind angle (if data
is available).
Sail time calculations
The Zeus Touch calculates the time and distance to a waypoint taking into consideration that
the vessel is sailing via a layline course to the waypoint and not taking a direct line from A to
B. Data shown using sail time calculations will be shown as below.
DTW-S = Distance To Waypoint - Sail
TTW-S = Time To Waypoint - Sail
ETA-S = Estimated Time of Arrival - Sail
Max/Min layline time
The time period that the max/min layline sector represents is determined by the laylines
settings menu.
Tidal Flow correction
The laylines displayed can be corrected for tidal flow via Chart settings. This setting adjusts
both laylines displayed on the chart and the laylines on the SailSteer screen.
