By using GPS trace, I have been able to calculate tacking angle. Best I have achieved so far with my D13 is 58 degrees. But question is, what is the optimum tacking angle in relation to VMG?

Does it exist any polar plots for the D13?
If not, does anyone know how to make one?

Polar plots for the D13 did not do, but I t hink that he should go no worse than 50 degrees.
