Abstract
A golf ball having improved aerodynamic efficiency is characterized by the arrangement of a plurality of modified tear-drop shaped dimples arranged on the surface thereof. The ball has a dimple-free equator which divides the ball into two identical hemispheres, each of which is broken into equal quadrants by two great circles passing through the poles of the ball. Each quadrant has a maximum circular area filled with a first plurality of tear-drop shaped dimples. A second plurality of tear-drop shaped dimples is arranged between the circular areas so that the dimple coverage on the ball is maximized.
