In the 1970s, Parker's Harvard crews continued to be successful. They did not win the Sprints in the years 1971–1973, but the losses were close. Then came the 1974 and 1975 Harvard varsities which are considered to be among the greatest in the history of the sport. They swept the collegiate competition, including dual races each year against the undefeated west coast champions Washington. Numerous team members went on to row for the national team. Post-season, the 1975 crew went to England to race at the Henley Royal Regatta. They finished second in the premier event of the regatta, the Grand Challenge Cup, losing to the British national team by two lengths.
