Abstract
This invention provides for a racquetball racquet combining enhanced ball acceleration, high precision, and comfort. These optimum characteristics are achieved though a racquetball racquet having, in combination, an overall length of between 500 mm and 580 mm, an unstrung weight of between 140 g and 195 g, a head weight of between 52% and 65% of the overall racquet weight, and a center of gravity located between 25 mm relative to the racquet head handle end and 75 mm relative to the distal head end, measured along the longitudinal axis of the racket. The longitudinal strings of the racquetball racquet extend from the racquet head handle end to the racket head distal end are arranged so as to diverge to form a V-configuration. Two neighboring longitudinal strings are each led to a common location on the racquet head handle end.
