Tack Assist

CAUTION

The watch 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. You are responsible for the safe and prudent operation of your vessel.

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

By default, the tack assist feature is set to automatic. Each time you calibrate the port or starboard COG, the watch 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.

Calibrating the Tack Assist

  1. From the watch face, select START.
  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 ().

  1. Select START.
  2. Select an option:
    • To calibrate the starboard side, select START.
    • 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.

To get the best lift estimate when using the tack assist feature, you can try these tips. See and for more information.

  • Enter a fixed tack angle, and calibrate the port side.
  • Enter a fixed tack angle, and calibrate the starboard side.
  • Reset the tack angle, and calibrate both the port and starboard side.

Sail Racing

You can use the device to help you cross the start line of a race exactly when the race begins. When you synchronize the regatta timer in the sail racing app with the official race countdown timer, you are alerted at one-minute intervals as the race start approaches. When you set the starting line, the device uses GPS data to indicate whether your boat will cross the start line before, after, or at the correct time to start the race.

Setting the Starting Line

  1. From the watch face, press START.
  2. Select Sail Race.
  3. Wait while the device locates satellites.
  4. Hold MENU.
  5. Select Start Line Settings.
  6. Select an option:
    • Select Mark Port to mark the port starting line mark as you sail past it.
    • Select Mark Starboard to mark the starboard starting line mark as you sail past it.
    • Select Time to Burn to enable or disable the time to burn data on the regatta timer data screen.
    • Select Distance to Start to set the distance to the start line, preferred distance units, and length of your boat.

Starting a Race

Before you can view the time to burn, you must set the starting line ().
