Tack Assist

While cruising or racing into the wind, the tack assist feature can help you determine if your boat is being lifted or headed. When you calibrate tack assist, the device captures your boat’s port and starboard course over ground (COG) measurements, and uses the COG data to calculate the mean true wind direction and the boat’s tack angle .

The device uses this data to determine whether your boat is being lifted or headed due wind shifts.

By default, the device tack assist is set to automatic. Each time you calibrate the port or starboard COG, the device recalibrates the opposite side and true wind direction. You can change the tack assist settings to enter a fixed tack angle or true wind direction.

NOTE: The device uses GPS-based course over ground to determine your course in the tack assist feature, and does not account for other factors that can affect your boat’s direction, such as currents and tides.

Calibrating the Tack Assist

  1. From the watch face, select MOB.
  2. Select Sail Race or Sail.
  3. Select UP or DOWN to view the tack assist screen.

    NOTE: You may need to add the tack assist screen to the data screens for the activity (Customizing the Data Screens).

  5. Select an option:
    • To calibrate the starboard side, select MOB.
    • To calibrate the port side, select DOWN.

      TIP: If the wind is coming from the starboard side of the vessel, you should calibrate starboard. If the wind is coming from the port side of the vessel, you should calibrate port.

  6. Wait while the device calibrates the tack assist.

    An arrow appears and indicates if your boat is being lifted or headed.

Entering a Fixed Tack Angle or True Wind Direction

  1. From the watch face, select MOB.
  2. Select Sail Race or Sail.
  3. Select UP or DOWN to view the tack assist screen.
  4. Hold MENU.
  5. Select Tack Angle or True Wind Direction.

  7. Select UP or DOWN to set the value.

Tips for Getting the Best Lift Estimate

To get the best lift estimate when using the tack assist feature, you can try these tips. See Entering a Fixed Tack Angle or True Wind Direction and Calibrating the Tack Assist for more information.

  • Enter a fixed tack angle, and calibrate the port side.
  • Enter a fixed tack angle, and calibrate the starboard side.
  • Use the Auto tack angle setting, and calibrate both the port and starboard side.
