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. 1 Select Settings > My Vessel > Vessel Type. 2 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 The start line guidance window is added to the Sail Racing combination screen by default. 1 From the Sail Racing combination screen, select Menu > 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. Sailing Features • To switch the position of the port and starboard marks after you have set them, select Swap Port & Starbd.. 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. 1 Mark the starting line (Setting the Starting Line, page 23). 2 From the Sail Racing combination screen, select Menu > Start Line Guidance > Target Speed, and select your target speed when crossing the starting line. 3 Select Target Time, and select the target time to cross the starting line. 4 Select Back. 5 Start the racing timer (Starting the Race Timer, page 23). Starting the Race Timer The race timer is added to the Sail Racing combination screen by default. 1 From the Sail Racing combination screen, select Start. NOTE: You can also access this from the Sailing SmartMode screen and the navigation chart. 2 When necessary, select Sync to synchronize with the official race timer. 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. 1 From a navigation chart, select Menu > Sailing > Start Line > GPS Bow Offset. 2 Enter the distance. 3 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 5), you can display laylines on the navigation chart. Laylines can be very helpful when racing. From the navigation chart, select Menu > Layers > My Vessel > Laylines > Setup. 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. 23
