The Dad Vail Regatta is the largest regular intercollegiate rowing event in the United States, drawing over a hundred colleges and universities from North America. The regatta has been held annually on the Schuylkill River in Philadelphia, Pennsylvania, since 1953. It was renamed the Jefferson Dad Vail Regatta in 2019 for new sponsor Thomas Jefferson University, a private university in Philadelphia, Pennsylvania, formed in 2017 through the merger of Philadelphia University and Thomas Jefferson University. It was renamed the Aberdeen Dad Vail Regatta in 2010 for sponsor Aberdeen Asset Management, a Scottish investment firm whose U.S. operations are headquartered in Center City Philadelphia.

Vail's passion for rowing helped form the modern-day Dad Vail Regatta and motivate the multitudes of colleges to come compete.

Marietta College, coached by Ellis MacDonald won the first leg on the new trophy by finishing second to a Penn sub-varsity boat, which was an added entry. Rutgers, coached by Ned Ten Eyck, was third and Manhattan College, coached by "Skippy" Walz was fourth. The race in 1935 was at Marietta.
