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 stores your boat's port and starboard courses over ground (COG), the mean true wind direction , and the vessel's tack angle .

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

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.
