ComNav Commander P2 Installation & Operation

Wind Shift (Wind Shift Alarm)

Wind Shift Delay

The Commander P2 can warn you if the wind shifts significantly. For example, if the Wind
Shift alarm is set to 10 and the Wind Shift Delay is set to 0.5, then if the wind shifts by more
than 10 degrees for 0.5 minutes, the Wind Shift Alarm will sound.
The Wind Shift Alarm can be disabled by selecting Wind Shift in the menu and rotating the
COURSE CHANGE counter-clockwise until the value reads "Off".

Preset Tack Angle

When the Vessel Type is set to "Sail" (in the Dockside Setup menu), the Commander P2
includes "Pretack" (Preset-Tack) in the list of possible Special Turns. The Preset Tack Angle
allows the user to customize the number of degrees that the boat will turn through when a
Preset-Tack Special Turn is executed.

Close Haul Def

Close Reach Def

Beam Reach Def

Broad Reach Def

Gybe Hold Point

The Commander P2 stores a definition for Close Haul, Close Reach, Beam Reach, Broad
Reach, and Gybe Hold Point. Each of these points of sail is defined by the angle of the wind
relative to the boat on either port or starboard tack. In the Alternate WIND mode, the
autopilot will steer the boat so as to maintain the wind angle at one of these points. Moving
the COURSE CHANGE knob one "click" will change from one of these points of sail to the
next.

These parameters should not be used. They are for a mode (NAV WIND mode) which was
available on some versions of the Commander P2. Use of NAV WIND mode is no longer
recommended or supported.
