Garmin GPSMAP 8000 Marine GPS System User Manual


 
Display: Sets how the laylines and vessel are shown 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.
Tide Correction: Corrects the laylines based on the tide.
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.

Select Settings > My Vessel > Keel Offset.
3
Select or based on the location of the transducer.

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 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.
Tacking and Gybing from Heading Hold
1
Engage heading hold (Engaging the Autopilot).
2
Select Menu > Autopilot Menu > Tack Gybe.
3
Select a direction.
The autopilot steers your boat through a tack or gybe.
Tacking and Gybing from Wind Hold
Before you can engage wind hold, you must have a wind sensor
installed.
1
Engage wind hold (Engaging Wind Hold).
2
Select Menu > Tack Gybe.
3
Select Tack or Gybe.
The autopilot steers your boat through a tack or gybe, and
information about the progress of the tack or gybe appears
on the screen.
Setting a Tack and Gybe Delay
The tack and gybe delay allows you to delay steering a tack and
gybe after you initiate the maneuver.
1
From the autopilot screen, select Menu > Autopilot Menu >
Autopilot Setup > Sailing Setup > Tack Delay.
2
Select the length of the delay.
3
If necessary, select Done.
Enabling the Gybe Inhibitor
NOTE: The gybe inhibitor does not prevent you from manually
performing a gybe using the helm or step steering.
The gybe inhibitor prevents the autopilot from performing a
gybe.
1
Select Menu > Autopilot Menu > Autopilot Setup > Sailing
Setup > Gybe Inhibitor.
