Abstract
A golf ball has a generally spherical surface and a plurality of dimples separated by a land area formed on the surface. The plurality of dimples includes a plurality of non-spherical dimples each having a non-axially symmetric plan shape, a varying edge angle, and a geometric centroid of the non-axially symmetric plan shape (GC). Each dimple cross-section of each non-spherical dimple consists of two arcs, each arc extending from a defined point of maximum dimple depth to a point at the land area of the golf ball. Each non-spherical dimple is oriented at an orientation angle, α, relative to a reference line. The orientation angle α is dependent on the position of the GC on the surface of the golf ball.

A golf ball having a generally spherical surface and comprising a plurality of dimples separated by a land area formed on the surface, wherein the plurality of dimples includes a plurality of non-spherical dimples each having a non-axially symmetric plan shape, a varying edge angle, and a geometric centroid of the non-axially symmetric plan shape (GC), wherein:
- each dimple cross-section of each non-spherical dimple consists of two arcs, each arc extending from a defined point of maximum dimple depth to a point at the land area of the golf ball;
- wherein each non-spherical dimple is oriented at an orientation angle, α, relative to a reference line, and
- wherein the orientation angle α is dependent on the position of the GC on the surface of the golf ball.
