Wind Vane Mode (Sailing Boats Only) - Raymarine p70 Installation And Operation Instructions Manual

Caution: Cross track error
correction
When returning to TRACK mode the autopilot will
correct the XTE in order to keep to the defined
track leg. The direction of turn may not coincide
with the bearing to waypoint and may be different
from that expected.
Route completion
The autopilot displays the Route Complete warning when you
have reached the last waypoint on a route.
Note: The 'Route Complete' alarm only sounds and displays
in conjunction with a multifunction display.
Leaving track mode
To leave Track mode:
1. Press AUTO to return to Auto mode (autopilot control), or.
2. Press STANDBY to return to Standby mode (manual
steering).

9.6 Wind vane mode (Sailing boats
only)
When the autopilot is in Wind Vane mode it uses the wind angle
as the primary heading reference. As changes in the true or
apparent wind angle occur, it adjusts the locked heading to
maintain the original wind angle.

You can only select Wind Vane mode if the autopilot is receiving
suitable SeaTalk, SeaTalk ng
Autopilots can maintain a course relative to either an apparent
or true wind angle in Wind Vane mode. The default setting is
Apparent wind. If required, you can change this to True wind
in the Sail Boat Settings menu: Menu > Set-up > Autopilot
Calibration > Sail Boat Settings > Wind Type.
Using wind vane mode
You can select Wind vane mode from either STANDBY or
AUTO mode:
1. Steady the vessel onto the required wind angle.
2. Select Wind vane mode:
i. Wind vane mode can be selected by pressing the Auto
and Standby buttons together, or
ii. selecting Wind vane mode from the modes menu: Menu
> Mode > Wind vane.
This will enable Wind vane mode and lock the current wind
angle. The display shows the locked heading (e.g. 128°)
and the wind angle (e.g. WIND 145P indicates a wind angle
of 145° to port).
3. The autopilot will then adjust the vessel's heading to maintain
the locked wind angle.
Adjusting the locked wind angle
1. You can adjust the locked wind angle by using the -1, +1,
-10 and +10 buttons, or the ROTARY controller to change
course. For example, to bear away by 10° when the boat
is on a starboard tack:
i. press -10 to turn the boat 10° to port – the locked wind
angle and locked heading will both change by 10°.
ii. the autopilot will then adjust the locked heading as
required to maintain the new wind angle.
Note: Because turning the vessel affects the relationship
between the true and apparent wind angles, you should only
use this method to make minor adjustments to the wind angle.
For major changes, return to STANDBY mode, steer onto the
new heading, then reselect Wind Vane mode. Refer to the
p70 pilot controller installation instruction for the procedure for
changing the wind reference between True and Apparent.
