Abstract
A golf ball includes a core and a cover surrounding the core. The cover includes a first hemispherical half and a second hemispherical half that define a seam line therebetween and along an outer surface of the cover. The seam line is non-planar and includes a repeating trapezoidal wave having a first portion disposed at a first latitude, a second portion disposed at a second latitude, and a linear ramping transition between the first portion and the second portion. The seam line further includes a first curvilinear wave superposed within the first portion of the trapezoidal wave, and a second curvilinear wave superposed within the second portion of the trapezoidal wave.
