Abstract
A golf ball having a plurality of dimples formed on its outer surface, the outer surface of the golf ball being divided into plural areas with dimples such that the golf ball is spherically symmetrical as defined by the United States Golf Association (USGA) Symmetry Rules, the plural areas configured such that the golf ball exhibits a lift coefficient (CL) of less than about 0.230 over a range of Reynolds Number (Re) from about 120,000 to about 180,000 and at a spin rate of about 3,500 rpm.
Claims22
A golf ball having a plurality of dimples formed on its outer surface, the outer surface of the golf ball being divided into plural areas with dimples such that the golf ball is spherically symmetrical as defined by the United States Golf Association (USGA) Symmetry Rules, the plural areas comprise at least first areas containing a plurality of first dimples and second areas containing a plurality of second dimples, the first dimples and the second dimples each being of at least two different sizes, the first dimples all being of smaller radius than the second dimples, and the first and second dimples being of different depths, the plural areas configured such that the golf ball exhibits a lift coefficient (CL) of less than about 0.230 over a range of Reynolds Number (Re) from about 120,000 to about 180,000 and at a spin rate of about 3,500 rpm.
