My attention was drawn to the app foil run for measuring upwind and down wind performance. Below is an example of where my Vmg seems to consistently top out using my Toyota PW.
i have some Ferrari’ in the form of an orbit and a afterburner to see how much better they are at going up wind for me
7 effective VMG Prv2 but I have seen others with obviously more skill than me push the same wing to 7.6 kt vmg.
it would be great if some of you could upload your gpx files to foil run and we can compare some of these PW’s
