Let us explain how raceQs works:
– on upwind legs the tool shows VMC – the speed toward the wind direction.
– on downwind and reaching legs the tool shows VMG – the speed toward the mark direction.
The upwind leg is defined as any destination point you can’t reach w/o at least one tack. This logic work works fine for most of the cases except two rear exception.
– Upwind leg when the boat on or above lay line – you are not supposed to hit the corners.
– Off wind leg if you went a wrong way and need to tack to reach the mark.
Looks like we need to add a switch when the user can chose VMG vs. VMC . Please provide your comments.
