© 2018, Annales Academiæ Scientiarum Fennicæ Mathematica. We study the chord-arc Jordan curves that satisfy the Cotlar-type inequality T*(f) ≲ M2(T f), where T is the Cauchy transform, T* is the maximal Cauchy transform and M is the Hardy-Littlewood maximal function. Under the background assumption of asymptotic conformality we find a characterization of such curves in terms of the smoothness of a parametrization of the curve.
