1, Rounding to Port or Stbd
2, Did black gain the overlap from behind
3, Had either of you tacked recently
4, I'm assuming you were both sailing close-hauled on proper coure
5, There have not been any wind shifts in the last few seconds

1. Rounding to Port
2. Look at the image, we were both in clear air, and the overlap was NOT gained from behind. We both sailed on port tack to the layline and tacked to starboard (both at the same time) our positions did not change. Positions do not change in tacticat unless you seriously mess up your controls.
3. No
4. Yes both close hauled on proper course.
