8.14 Race Start Line (SmartStart) and Race Timer

The Race Start Line and Race Timer features can help you achieve a better racing start. The features
assist you in approaching the race start line at the optimum speed, angle and time.
The basic concept of an effective race start is to guide your vessel and tune the sail configuration in
an optimum way to ensure you are approaching the start line at the very last moment with full power.
In race sailing, the countdown to this last moment is known as "Time to Burn".
The race start line features help you to do this by providing a visual indication of the position of the
race line on the Chart, as well as key data, including race timer, distance to start line, line bias, and
Time to Burn. These features can also be used in conjunction with Laylines to further assist you in
optimizing your approach to the start line. When the Race Start Line, Race Timer and Laylines are
active, Laylines will visually protrude from the race start line's port and starboard ends to help guide
your vessel on an optimum course to the start line.
For more information on Laylines, refer to:
