3 Advanced Operation
The ST4000+ will then adjust the boat’s heading to maintain the
locked apparent wind angle.
Exiting Wind Vane mode
You can return to Auto or Standby mode from Wind Vane mode by:
• pressing auto to return to Auto mode
• pressing standby to steer manually in Standby mode
Adjusting the locked wind angle
You can adjust the locked wind angle by using the -1, +1, -10 and +10
keys to change course. For example, to bear away by 10° when the
boat is on a starboard tack:
•press -10 to turn the boat 10° to port – the locked apparent wind
angle and locked heading will both change by 10°
• the autopilot will then adjust the locked heading as required to
maintain the new apparent wind angle
Note: Because turning the boat affects the relationship between the
true and apparent wind angles, you should only use this method to
make minor adjustments to the apparent wind angle. For major
changes, return to Standby mode, steer onto the new heading, then
reselect Wind Vane mode.
Note:
Dodges in Wind Vane mode
When the autopilot is in Wind Vane mode you still have full control
from the keypad.
