ComNav Commander P2 Installation & Operation
For example, assume that you have defined a Close Reach as 60° and a Beam Reach as 90°
to the apparent wind. You are in WIND mode and the autopilot is steering to the wind at an
apparent wind angle of 94° on a port tack.
When you press the AUTO button to bring up the Alternate WIND mode, the autopilot will
change the commanded wind angle to 90°, because the current angle of 94° is closest to the
Beam Reach definition of 90°. The display will show a solid arrow indicating the approximate
wind direction at 90°. The autopilot will steer the boat from the present wind angle of 94° to
the commanded wind angle of 90°.
Now let's say you turn the COURSE CHANGE knob one click counter-clockwise. The
commanded wind angle changes to 60° and an outline arrow appears on the screen to show
that the wind will be coming from 60° once the autopilot brings the vessel onto the new
commanded wind angle. The boat will turn to port and as the apparent wind angle
approaches 60°, and the outline arrow will be replaced with a solid one.
The Commander P2 will not allow you to Tack or Gybe using the COURSE CHANGE knob,
when the alternative wind display is shown.
To tack you must bring the vessel to the Close Haul Def Point, and then use the TURN button
to perform the tack. See the section on, above, as well as Special Turns later in this chapter
for more information.
To gybe, use the COURSE CHANGE knob to bring the vessel to the Gybe Hold Point, and
then use the TURN button to perform the Gybe. See the section on Gybing, above, as well
as Special Turns later in this chapter for more information.
