Sailing Features

Setting the Vessel Type

You can select your boat type to configure the chartplotter

settings and to use features customized for your boat type.

Select Settings > My Vessel > Vessel Type.

Select an option.

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

From the starting line guidance gauge, select MENU > Start

Line.

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.

• To switch the position of the port and starboard marks

after you have set them, select Swap Port & Starbd.

Marks.

Using the Starting Line Guidance

You can use the starting line guidance feature to help get you

cross the start line, at the optimal speed during a sailing race.

Mark the starting line (Setting the Starting Line, page 22).

From the Start Line Guidance gauge, select MENU > Target

Speed, and select your target speed when crossing the

starting line.

Select Target Time, and select the target time to cross the

starting line.

Select BACK.

Start the racing timer (Using the Race Timer, page 22).

Using the Race Timer

From the starting line guidance gauge, select or to set

the timer.

Select SELECT to start and stop the timer.

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.

From the starting line guidance gauge, select MENU > Start

Line > GPS Bow Offset.

Enter the distance.

Select SELECT.

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 2), you

can display laylines on the navigation chart. Laylines can be

very helpful when racing.

From the navigation chart, select MENU > 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.

Tide Correction: Corrects the laylines based on the tide.

Filter Time Constant: 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
