The tournament was sponsored by Royal Dutch Shell, with matches played from 22 January to 23 April 1971.
Five teams contested the competition – Barbados, the Combined Islands, Guyana, Jamaica, and Trinidad and Tobago. Trinidad and Tobago and Jamaica both won two and drew two of their four matches, but Trinidad and Tobago finished with more points, winning a second consecutive title. Trinidadian batsman Joey Carew led the tournament in runs for a second consecutive season, while Jamaican fast bowler Uton Dowe was the leading wicket-taker.
