On Sunday morning, rowers and fans alike trooped out to the Thames River in New London, Conn., by foot, by car and by train to witness the 149th anniversary of America’s oldest intercollegiate athletic event.

Featuring a marathon among crew races, a showdown between ancient rivals and an end to some collegiate rowing careers, the Harvard-Yale regatta promised competition of the highest level.

And, indeed, it proved to be a regatta of the highest sort—for Harvard anyway.

In grand fashion, the Harvard heavyweight crew finished its season with a sweep over Yale in the 136th racing of the Harvard-Yale regatta.

In all three of the races, Harvard dominated completely, taking control of the races with shockingly large leads.

The Harvard varsity boat (6-1) raced the four-mile upstream course in the sixth- fastest time in the history of the regatta and the fourth-fastest time upstream.

Senior coxswain Jon Cahill, aware of Yale’s (4-3) penchant for early leads, got the Crimson off to a fast start, with an early eight-seat lead.

Harvard’s advantage increased to almost two lengths at the half-mile mark, giving the Crimson enough padding to withstand a port-side crab at the three-quarters-mile mark.
