ABSTRACT:
In a golf ball, dimples are arranged in its spherical surface such that a great circle which does not intersect with the dimples is not drawable on the ball surface, thereby preventing any drop of symmetry caused by the presence of a seam line. The dimples are further arranged such that a percent dimple volume VR given as (B/A).times.100% is in the range: 0.6%<VR<1.5% wherein a phantom sphere given on the assumption that the spherical surface of the ball is free of dimples has a volume of A mm.sup.3 and the sum of the volumes of dimples distributed throughout the ball is B mm.sup.3, thereby optimizing the percent dimple volume to ensure a longer carry.
