An invitation event for women's eights was added in 1998. In 2000, this was replaced by an open women's eights event under the same rules as the Grand Challenge Cup. In 2002, the Remenham Challenge Cup was donated by Remenham Club as the trophy for this event. At the 2001 Regatta, an open event for Women's Quadruple Sculls was introduced. In 2003, this event became known as the Princess Grace Challenge Cup in memory of Princess Grace of Monaco. Her father, John B. Kelly Sr., had been controversially excluded from the Diamond Sculls in 1920 because of the regattas rules on amateurism; her brother, John B. Kelly Jr. had won the Diamonds Sculls in 1947 and in 1949. Princess Grace was the Regatta prizegiver in 1981.
