Operation Manual

Stopping the Race Timer
From the Sail Racing combination screen, select Stop.
Setting the Distance between the Bow and the GPS
Antenna
You can enter the distance between the bow of your boat and
the location of your GPS antenna. This helps ensure the bow of
your boat crosses the starting line at the precise start time.
1
From a navigation chart, select Menu > Sailing > Start Line
> GPS Bow Offset.
2
Enter the distance.
3
Select
Done.
Laylines Settings
To use the laylines features, you must connect a wind sensor to
the chartplotter.
When in sailing mode (
Setting the Vessel Type, page 4), you
can display laylines on the navigation chart. Laylines can be
very helpful when racing.
From the navigation chart, select Menu
> Sailing > Laylines
.
Display: Sets how the laylines and vessel appear on the chart,
and sets the length of the laylines.
Sailing Ang.: Allows you to select how the device calculates
laylines. The
Actual option calculates the laylines using the
measured wind angle from the wind sensor. The Manual
option calculates the laylines using manually entered
windward and leeward angles.
Windward Ang.: Allows you to set a layline based on the
windward sailing angle.
Leeward Ang.: Allows you to set a layline based on the leeward
sailing angle.
Tide Correction: Corrects the laylines based on the tide.
Layline Filter: Filters the layline data based on the time interval
entered. For a smoother layline that filters out some of the
changes in the boat's heading or true wind angle, enter a
higher number. For laylines that display a higher sensitivity to
changes in the boat's heading or true wind angle, enter a
lower number.
Setting the Keel Offset
You can enter a keel offset to compensate the surface reading
for the depth of a keel, making it possible to measure depth from
the bottom of the keel instead of from the transducer location.
Enter a positive number to offset for a keel. You can enter a
negative number to compensate for a large vessel that may
draw several feet of water.
1
Complete an action, based on the location of the transducer:
• If the transducer is installed at the water line
À
, measure
the distance from the transducer location to the keel of the
boat. Enter this value in steps 3 and 4 as a positive
number.
• If the transducer is installed at the bottom of the keel
Á
,
measure the distance from the transducer to the water
line. Enter this value in steps 3 and 4 as a negative
number.
2
Select Settings > My Vessel > Depth and Anchoring >
Keel Offset.
3
Select or based on the location of the transducer.
4
Enter the distance measured in step 1.
Sailboat Autopilot Operation
CAUTION
When engaged, the autopilot controls only the rudder. You and
your crew remain responsible for the sails while the autopilot is
engaged.
In addition to heading hold, you can use the autopilot to maintain
a wind hold. You can also use the autopilot to control the rudder
while tacking and gybing.
Wind Hold
You can set the autopilot to maintain a specific bearing relative
to the current wind angle. Your device must be connected to a
NMEA 2000
or NMEA
®
0183 compatible wind sensor to perform
a wind hold or a wind-based tack or gybe.
Setting the Wind Hold Type
Before you can enable the wind hold type, you must connect a
NMEA 2000
or NMEA 0183 wind sensor to the autopilot.
For advanced autopilot configuration, see the installation
instructions included with your autopilot.
1
From the autopilot screen, select Menu > Autopilot Setup >
Wind Hold Type.
2
Select Apparent
or True.
Engaging Wind Hold
Before you can enable the wind hold type, you must connect a
NMEA 2000 or
NMEA 0183 wind sensor to the autopilot.
When the autopilot is in standby mode, select Wind Hold.
Engaging Wind Hold from Heading Hold
Before you can enable the wind hold type, you must connect a
NMEA 2000 or
NMEA 0183 wind sensor to the autopilot.
With heading hold engaged, select
Menu >
Wind Hold
.
Adjusting the Wind Hold Angle with the Autopilot
You can adjust the wind hold angle on the autopilot when wind
hold is engaged.
• To adjust the wind hold angle in increments of 1°, select or
.
• To adjust the wind hold angle in increments of 10°, hold or
.
Tack and Gybe
You can set the autopilot to perform a tack or gybe while
heading hold or wind hold is engaged.
