Synchronizing User Data Across the Garmin
Marine Network
Before you synchronize the user data across the network, you
should backup your user data to prevent possible data loss. See
Backing Up Data to a Computer, page
You can share waypoints, tracks, and routes with all compatible
devices connected to the Garmin Marine Network (Ethernet)
automatically.
NOTE: This feature is not available on all models.
Select Settings > Preferences > User Data Sharing > On.
If a change is made to a waypoint, track, or route on one
chartplotter, that data is synchronized automatically across all
chartplotters on the Ethernet network.

You can select your boat type to configure the chartplotter
settings and to use features customized for your boat type.

Sail Racing

You can use the device to increase the likelihood that your boat
will cross the start line of a race exactly when the race begins.
When you synchronize the race timer with the official race
countdown timer, you are alerted at one-minute intervals as the
race start approaches. When you combine the race timer with
the virtual start line, the device measures your speed, bearing,
and remaining time on the countdown timer. The device uses
this data to indicate whether your boat will cross the start line
before, after, or at the correct time to start the race.

Starting Line Guidance

Sailing start line guidance is a visual representation of the
information you need to cross the start line at the optimal time
and speed.
After you set the starboard and port start line pins, and the
target speed and time, and after you start the race timer, a
predictor line appears. The predictor line extends from your
current location toward the start line and the laylines that extend
from each pin.
The end point and color of the predictor line indicate where the
boat will be when the timer expires, based on your current boat
speed.
When the end point is before the start line, the line is white. This
indicates the boat must increase speed to reach the start line on
time.
When the end point is past the start line, the line is red. This
indicates the boat must reduce speed to avoid a penalty for
reaching the start line before the timer expires.
When the end point is on the start line, the line is white. This
indicates the boat is moving at an optimal speed to reach the
start line when the timer expires.
By default, the start line guidance window and the race timer
window appear in the Sail Racing combination screen.

Setting the Starting Line

The start line guidance window is added to the Sail Racing
combination screen by default.
