Abstract

The multiple dimpled golf ball has 78% or more of its surface covered with dimples. For a golf ball with a total of 414 dimples, 144 dimples have a diameter of 0.14 inches and 270 dimples have a diameter of 0.15 inches. If no dimples are removed from the poles, then the golf ball has 422 dimples.

Claims

1. A golf ball having dimples comprising at least 78% of the surface area of the golf ball covered by said dimples, said dimples being divided into at least two sets of dimples, a first set of dimples having an identical nominal dimple diameter and a second set of dimples having an identical nominal dimple diameter, the first set of dimples having a diameter smaller than the diameter of the second set of dimples, the golf ball being selected from the group of golf balls having a total number of dimples consisting of:

414 and 422.

2. A golf ball having 414 dimples said 414 dimples being divided into two sets of dimples comprising a first set of dimples wherein each dimple has a nominal dimple diameter of 0.140 inches and a second set of dimples wherein each dimple has a nominal dimple diameter of 0.150 inches.

3. The golf ball of claim 2 wherein the total number of dimples is about 422.
