ABSTRACT:
A spherical golf ball (10) is provided with at least 500 dimples and 30 bald patches symmetrically disposed over the surface of the ball, the disposition of the dimples being substantially the same in each of twelve regions (11) of the surface of the sphere which are defined by projecting on to the surface the edges of a regular dodecahedron. At the mid point of each edge of the dodecahedron there is a bald patch (20, 21, 22, 23, 24). Each bald patch has the shape of a spherical rectangular dumbbell, a surface area of from 1.0 to 2.5 times the mean dimple area and does not enclose any dimple or part thereof.
