A golf ball with a plurality of recessed dimples having a shape in accordance with a certain mathematical ratio on the surface thereof is disclosed. The value of the spatial volume of each dimple below a plane defined by an edge of the dimple divided by the volume of a cylinder, wherein the bottom of the cylinder is defined by the plane and the height is determined by the maximum depth of the dimple from the plane, is within the range of 0.35 to 0.43. The dimples having such a shape represent at least 90 percent of the total number of dimples on the golf ball. The maximum diameter of the dimple can be within the range of 2 to 4 mm and the maximum depth of the dimple can be within the range of 0.1 to 0.4 mm. This configuration results in a golf ball having an increased carry.
A golf ball having a plurality of recessed dimples on the surface thereof, wherein said dimples have a shape wherein the value of the spatial volume of each dimple below a plane defined by an edge of the dimple divided by the volume of a cylinder wherein the bottom of said cylinder is defined by said plane and the height is determined by the maximum depth of the dimple from said plane, is within the range from 0.35 to 0.43, wherein the maximum diameter of the dimple is within the range of 2-4 mm and the maximum depth of the dimple is within the range of 0.1-0.4 mm, said dimples representing at least 90 percent of the total number of dimples on said golf ball.
A golf ball having a plurality of recessed dimples which in plan view have a circular shape, wherein the value of V.sub.0 of said dimples ranges from 0.35 to 0.43, wherein V.sub.0 is determined by the method comprising the steps of:
