<p>A practice sporting or recreational ball, particularly a golf ball, arranged to be impelled through the air includes a ball body (10) and a drag member (20). The drag member (20) may be in the form of a tail member (22) secured to the body (10) by a stiff cord (24) so as to trail behind the body (10) and impart spin from the body (10) to the tail member (22). The cord end(s) may be embedded in the body (10) or may be secured to a loop (50) in the casing of the body (10). Alternatively, the drag member (20) may include a pocket which receives a conventional ball. The tail member (22) has a fabric body (23) made of a non-wettable or hydrophobic material such as dacron sail cloth.</p> |
