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.

By default, the start line guidance window and the race timer window appear in the Sail Racing combination screen.

Before you can view the starting line guidance information, you must define the port and starboard points of the start line (Setting the Starting Line).

1

Start line indicator. This line is defined by the port and starboard points you specify.
2

Port and starboard laylines.

The solid lines show the laylines in relation to each start point.
3

Predictor line. This appears after you define the port and starboard pins, the target speed and time, and you start the race timer.

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.
4

Desired speed when crossing the start line or Target Speed from the polar table.
5

Start line bias information. This indicates which end of the start line, port or starboard, you should try to target when approaching so you can cross the starting line at the fastest speed based on present wind and other conditions.

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).
  2. From the Sail Racing combination screen, select Options > Start Line Guidance > Target Speed, and select your target speed when crossing the starting line.
    TIP: You do not have to set your target speed if you have loaded a polar table ( Polar Tables).
  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).
