Good starts are all about time and distance. If you sail in a class that allows pinging the line, you ping the line. Did you know that your GPS records all those button presses? The right software can show you exactly where the line was and your boat in relation to the line.
With accurate mark positions, you can then measure your distance to the start line and how long it took you to reach the line.
ChartedSails does all of the above, is compatible with all popular GPS devices and synchronizes tracks from multiple boats for maximum bragging pleasure.
