Abstract
A golf ball having an outside surface with a plurality of dimples formed thereon. The dimples on the ball have a cross-sectional profiles formed by a catenary curve. Shape constants in the catenary curve are used to vary the ball flight performance according to ball spin characteristics and player swing speed.
