• Wind Hold Type—(sailboats only) autopilot steers to apparent wind
or true wind when wind hold is engaged. For both true and apparent
wind, wind angle is calculated in reference to the bow of the boat, and is
represented in degrees to port or starboard.
NoTe: The option to switch between wind-hold types is only available
if your boat is equipped with both a wind sensor and a water speed
sensor.
◦ Apparent wind speed reflects the flow of air actually experienced
while on a boat. Apparent is the only available wind hold option if
your boat is equipped with a wind sensor and no water speed sensor.
◦ True wind data reflects the flow of air experienced with reference
to the speed of the boat. Select True or Apparent if your boat is
equipped with a wind sensor and a water speed sensor.
• Wind Limiter—(sailboats only) during a gybe, the wind limiter slows
the rate of turn as the wind direction approaches the stern. If the rate of
turn is too slow, decrease the wind limiter value. If the rate of turn is too
fast, increase the wind limiter value.
Power Mode
You can enable a power mode to help reduce rudder activity.
Changing the Power Mode
1. From the heading screen, select Menu > Setup > User Autopilot
Configuration.
2. Select an option:
• Select Power Mode > economy to enable economy power mode.
• Select Power Mode > Normal to return to normal operation.
Customizing the Power Mode
You can adjust the level of rudder activity while in economy power mode.
1. From the heading screen, select Menu > Setup > User Autopilot
Configuration > Power Saver.
2. Select a percentage and select Done.
A higher percentage setting will reduce rudder activity at the expense of
heading performance. Therefore, the higher you set the percentage, the
more your course will deviate before the autopilot corrects it.
TIP: In choppy conditions at low speeds, increasing the Power Saver
percentage will reduce rudder activity and reduce wear on the autopilot
system.
