ABSTRACT:
A golf ball characterized by enhanced flight distance and enhanced aerodynamic symmetry, the ball having a generally spherical surface with dimple patterns thereon, the improvement comprising between about 75% and 85% of the ball spherical surface occupied by the dimples; there being smaller and larger dimples, all of which have diameters within the range of about 0.110 to 0.150 inches. There are dimple-free multiple great circle arcs on the ball surface, which define n-sided spherical surface polygons associated with opposite polar zones, with n.sup.2 -2n of the smaller dimples within each polygon. The ball also has an equator, and great circle arcs also defining multiple spherical surface triangles with legs on the equator, there being n.sup.2 +2n of the smaller dimples within each triangle.
