GOLFbal

GOLFbal is a small spherical object used in the sport of golf. In official play, conforming golf balls must have a diameter no less than 1.680 inches (42.67 mm) and a mass not exceeding 1.620 ounces (45.93 g). Modern golfbal designs employ dimples on the surface to optimize flight, stability, and distance.

Construction and varieties

Golfbal constructions vary by number of layers. Two-piece balls typically feature a solid core with a durable cover and are favored for distance and durability. Three-piece and four-piece balls add mantle layers between the core and cover to adjust spin, feel, and control around greens. Cover materials include ionomer polymers (such as Surlyn) for durability and urethane for enhanced feel and spin potential. Dimple patterns and surface textures differ across models, influencing aerodynamics, lift, and descent angles.

Regulation and conformity

Governing bodies, notably the USGA and The R&A, regulate golfbal specifications to ensure conformity in competition. Balls sold for play must meet established size, weight, and performance standards. Manufacturers test conforming balls for accuracy, durability, and consistency, while players select models based on preferred spin, distance, and feel characteristics.

History and development

Early golfbal history features leather-infused balls and gutta-percha balls, with the latter becoming widespread in the 19th century. The introduction of dimpled surfaces in the 20th century significantly improved distance and stability. Since then, golfbal design has evolved with multi-layer cores, refined mantles, and advanced cover materials to balance speed, spin, and control for various playing styles and conditions.

Usage and market

Golfbal are produced by numerous brands and varieties, catering to different skill levels and courses. Players choose models based on performance attributes, feel, and durability, contributing to a diverse market of options for practice and competition.
