A restricted trajectory golf ball which resembles a U.S.G.A. approved regulation long range golf ball. The ball construction comprises a spherical coherent impact damping mass operative in dissipating golf club impact energy such that limited rebound energy is available for ball propulsion. The surface contouring disposed upon the damping mass function to provide advantageous aerodynamic effects and may take the form of standard dimples or dimples which are deeper than standard. That is if surface dimples are used, the dimple depth can be adjusted to assist toward providing a ball having the required restricted trajectory. Due to physical and structural characteristics, the ball is characterized as being firm, substantially durable, exhibiting a "click" sound when hit, and having a flight range of approximately one-half to one-quarter the range of regulation balls when hit with a No. 1 Wood in the same manner and under the same weather conditions. Since the flight range of the invented ball is intermediate long range regulation and short range practice balls, it is ideal for use within small indoor and outdoor driving ranges or on short golf courses of the Par-3 type. When used on Par-3 courses, the courses can be converted to operate on a par rating basis equivalent to those of U.S.G.A. approved regulation golf courses so that attained scores can be considered representative of scores a golfer should attain on a regulation course of similar complexity. |
