Settings • 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. 18 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. GHC 10 Owner's Manual
