ABSTRACT:
A golf ball (10) has a plurality of dimples in its outer surface. At least 10% of the dimples are so disposed relative to one another that any two adjacemt dimples overlap. The region of each overlap may have a maximum width of from 1% to 20% of the diameter of the larger of any two overlapping dimples. Preferably, the dimples are arranged in a repeating pattern over the whole surface of the ball. The pattern may be defined by projecting on to the ball the edges of a regular dodecahedron (11, 12, 13, 14, 15, 16, 17, 18, 19 and 20) so that the ball is notionally divided into twelve regular pentagons (one shown - 21).
