Steer to wind modes

Steer to wind modes use your autopilot to steer your vessel to the wind. You can steer either to the Apparent Wind Angle (AWA), True Wind Angle (TWA), or to a target wind angle from a polar table.

Note

For the Steer to Wind modes to be available:

  • Wind and Heading data must be available on the network.

  • Your autopilot must be configured as a sailing Boat type / Vessel hull type. Refer to the commissioning instructions for your autopilot for details on how to configure the Boat type / Vessel hull type.

  • Steer to Polar mode requires a valid polar table to be configured on your chartplotter.

  • Steer to Polar also requires the wind angle to be within 30° of the polar target.

The available wind modes are:

  • Steer to Wind (T) — Use the True Wind Angle (TWA) to maintain a fixed wind angle over water, observed when stationary, and relative to the vessel’s bow.

  • Steer to Wind (A) — Use the Apparent Wind Angle (AWA) to maintain a fixed wind angle when the vessel is in motion, relative to the vessel’s heading, and at any point of sail.

  • Steer to Polar — Only available when the chartplotter’s Sail performance setting is set to Polar. Use Steer to Polar to achieve optimum upwind (or downwind) performance based on your polar table.
