For example, to bear away by 10° when theboat is on a starboard tack:• press -10 to turn the boat 10° to port – the locked apparent windangle and locked heading will both change by 10°• the autopilot will then adjust the locked heading as required tomaintain the new apparent wind angleNote: Because turning the boat affects the relationship between thetrue and apparent wind angles, you should only use this method tomake minor adjustments to the apparent wind angle. For majorchanges, return to Standby mode, steer onto the new heading, thenreselect Wind Vane mode.Returning to the previous apparent wind angle(LAST WND)If you have steered the boat away from the selected apparent windangle for any reason (such as a dodge maneuver or selecting Standbymode), you can return to the previous locked wind angle:1.
