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. Multiple great circle arcs on the ball surface define six-sided spherical surface hexagons on axially opposite polar zones. Smaller dimples within each such hexagons are grouped in clusters of four, symmetrically about an axis of the ball centrally intersecting the hexagons.

The geodesic lines intersect to form six like isosceles spherical triangles respectively adjacent the six sides of each hexagon, and there re additional dimples confined by the triangles, with all dimples confined by each triangle being completely with each triangle. Each geodesic line has a length between its opposite ends which is at least 20% of its surface circumference of the golf ball. The golf ball has an equatorial region everywhere spaced from the spherical hexagons and the dimple density per unit area at the equatorial region is greater than the dimple density per unit area in the spherical hexagons.
