In 1922 he won the Stewards’ with Eton Vikings and the Visitors’ with Third Trinity and, the following year, he again won the Visitors’, this time with Third Trinity, and rowed for Eton Vikings in the Grand. His finest year was probably 1924. He began as a member of the Cambridge crew that scored an upset victory over Oxford in the Boat Race, at Henley he won the Goblets partnering Maxwell Eley and the Stewards’ with Third Trinity and finished the year on a winning note when the Third Trinity crew won the coxless fours at the 1924 Olympic Games.
