Patent ID: 7261651

Claim:
A golf ball comprising a spherical surface with numerous dimples thereon, the ball being characterized in that the dimples have a diameter of 2 to 6 mm and number in all from 250 to 330, of which at least 60% are large dimples having a diameter of at least 4.5 mm, and in that the volume of space in a dimple below a planar surface circumscribed by an edge of the dimple, summed for all the dimples on the surface of the ball, is from 320 to 360 mm 3 , wherein the value obtained when the volume of space in the dimple below the planar surface circumscribed by the dimple edge is divided by the volume of a cylinder whose base is the planar surface and whose height is the maximum depth of the dimple from the base, averaged for all the dimples, is from 0.40 to 0.49.
