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.
1 From the Sail Racing combination screen, select Options > Start Line Guidance > Start Line.
2 Select an option:
• To mark the port and starboard starting line marks as you sail past them, select Ping Marks.
• To mark the port and starboard starting line marks by entering their coordinates, select Enter Coordinates.
