Golf ball

Abstract

The invention provides a golf ball having a solid core, a cover of at least one layer, and a plurality of dimples on a surface of an outermost layer of the cover. The dimples have a volume ratio (VR) of from 1.0 to 1.4%. The ball has an initial velocity, as measured using an initial velocity measuring apparatus of the same type as a USGA drum rotation-type initial velocity instrument, of from 75.5 to 77.7 m/s, and a ratio of total distance traveled when struck at a head speed of 54 m/s to total distance traveled when struck at a head speed of 35 m/s (HS54/HS35) of from 1.30 to 1.50. This golf ball is able to substantially reduce the distance traveled by the ball when struck at a high head speed, while at the same time holding down the decrease in distance when struck at a low head speed.

1 . A golf ball comprising a solid core, a cover of at least one layer, and a plurality of dimples on a surface of an outermost layer of the cover, wherein the dimples have a volume ratio (VR) of from 1.0 to 1.4% and the ball has an initial velocity, as measured using an initial velocity measuring apparatus of the same type as a USGA drum rotation-type initial velocity instrument, of from 75.5 to 77.7 m/s and a ratio of total distance traveled when struck at a head speed of 54 m/s to total distance traveled when struck at a head speed of 35 m/s (HS54/HS35) of from 1.30 to 1.50.
