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.

From a navigation chart, select Menu > Sailing > Start Line

> GPS Bow Offset.

Enter the distance.

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.

Complete an action, based on the location of the transducer:

• If the transducer is installed at the water line

, 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

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 > Depth and Anchoring >

Keel Offset.

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.

From the autopilot screen, select Menu > Autopilot Setup >

Wind Hold Type.

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.
