Start Line - IB-Sailing Software

The app can present start line data and have it also on the GPS track.

Start Line Fields

Line Dist At Gun -> Distance to the start line at the gun. Negative values mean that the boat was over the line.

Line Time -> time when the boat crosses the line. Positive numbers are after the gun, and negative before

Pos At Start -> Position where the line was crossed. 0% would be at the RC and 100% at the pin end

Bias Used -> how much of possible bias was used when crossing the line

DT Lead -> upwind distance to leader at the gun and at the time set

SOG gun -> speed over ground at the gun
