Installation

WIND Apparent’ is selected when you only want to steer to apparent wind. Apparent wind steering is preferred when you want to achieve maximum boat speed. The autopilot will try to maintain a constant apparent wind angle to get maximum thrust from a given trim of the sails.

WIND True’ is selected when you only want to steer to true wind. When sailing in closed waters, the apparent wind angle may change temporarily due to wind gusts. It may then be preferred to sail to the true wind.

VMG Optimizing

The VMG (to wind) parameter can only be enabled or disabled when ‘Wind setup’ is set to ‘RACING’. It is disabled in the ‘NORMAL’ sub-mode.

When enabled, the VMG optimizing will be active for 5 – 10 minutes after a new wind angle has been set. It will only be activated when beating.

‘VMG’ will be displayed in the lower left corner when the VMG optimizing feature is active.

Range: Enabled/Disabled

Default: Disabled

Layline Steering

‘Layline steering’ can only be enabled or disabled when ‘Wind setup’ is set to ‘RACING’. It is enabled in the ‘NORMAL’ sub-mode.

Layline steering is useful when navigating. It will use the Cross Track Error (XTE) from the navigator to keep the boat on the track line. If the XTE from the navigator exceeds 0.15 nm, the autopilot will calculate its own layline towards the waypoint and follow that. Layline steering is not active when turning, tacking or gybing.

‘XTE’ will be displayed in the lower left corner when layline steering is active.

Range: Enabled/Disabled

Default: Enabled
